Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
Like 'truckfighters' and 'SoftWireEngineer', I too once recently had a problem with my SB3 that was fixed by unplugging/replugging the power source. When turning on the stereo system, a low-level but mid-to-high tone whining sound was coming through the speakers. I didn't know at first what component it was coming from, and at that time I was using the analog-outs of the SB3. During my troubleshooting steps, I noticed that when I unplugged the network cable from the SB3, the sound stopped after about 5-10 seconds (as the SB3 ultimately reacted to losing the network connection). Since the sound did persist for that 5-10 second period after unplugging the network cable, and since no other cable but the power was connected to the SB3 at the time, the sound was clearly coming from the SB3 itself and through its analog-outs. Finally, unplugging/replugging the power connection at the SB3 got rid of the whine sound - and fortunately it hasn't returned (although I am running digital-out to a DAC now, so even if the issue did occur again, it might not be as noticeable again). -- NewBuyer NewBuyer's Profile: http://forums.slimdevices.com/member.php?userid=7862 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Not reproducible off-site, given known data, and not reproducible at all are two different things. Funny you should mention cars! My swedish made car from some years ago, who's brand shall remain name-less, but starts with an "S", had a scary brake problem that only I experienced, and I was unable to reproduce at will. S**B tested the car and replaced various parts. The never found any problem, but they never hinted that I might be imagining things. Later the MOT (annual test) guys discovered that a brake hose had a flaw in the wall that allowed a rubber balloon to form outside the hose at certain pressures -thus instantly reducing hydralic pressure to zero.

I don't know if you have noticed, but today Windows gathers local information about the problem on the actual computer where the problem occurs. Recreating the massive amount of possible permutations of end user configurations in the lab is too time consuming just to see if there actually is a bug.

The DT-Passthrough ability pretty well removes oddities like that from the digital outputs. If there was such a problem, encoded material would sound not just subtly off, but like noise. (The SB and Transporter are both dumb: they just decode flac and put it on the output... they don't bother with transforming it in any way...) No one has complained that playing DTS encoded flacs makes the second track go to white noise until you pause/play it.

As a user I have no real insight into what is going on in there. Are there not possibilities of processes misbehaving -CPU hogging, for example, screwing up (to some degree) real-time demands? Perhaps looking into the more advanced debugging options could be a possibility to see if things are problematic? Can Slimserver alter play back quality on the fly (or after pause) if bandwidth is decided to be too low? Or is the transcoding option a static function only? (I haven't used this feature much.)

I'm not sure why Logitech seem to base all responses on the assumption that their product is flawless? I have never heard of a body of code that is bug-free. Also, end-users can't be expected to roll out a full-fledged digital and EE test environment. Not even if they are "positive" they can hear a problem. I agree that placebo is the most likely casuse here, but the initial discovery is less likely to be a placebo effect since it seems like one of those unexpected findings. -- P Floding No, I didn't ABX it.

Possible but I seriously doubt that. Personally, I run english versions of virtually all software including SlimServer and OS so I can't test for this. I find it weird that some SW still can't be 8-bit clean for characters, it used to be a problem back in the 80s and early 90s when you needed to use separate libs to use 8-bit char sets. That really should be a problems of the past. That said, it would of course be possible that some mismatch between characters could cause a pointer errror some where causing really weird errors but those kind of programming errors and/or bugs in libs, etc. almost never causes and reproducable misbehauvious, instead they cause the software to crash at random times and places in the SW. -- johann johann's Profile: http://forums.slimdevices.com/member.php?userid=10177 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

We each hear with our own ears, in our own rooms, though our own minds etc. Unfortunately that sort of philosophy doesn't help us all get together to fix something, because if there is a fault to fix it must be reproducible and observable by more than Omega. The reason why he is taking some flack is because - read the title - he claimed this second playing effect was a DESIGN MISS (implied = FAULT) in the slim devices product. It might be, but if it is a design fault, then it is *repeatable for different observers*. Different observers were unable to repeat it. Omega might still have a sample fault, in which case it will be repeatable - but for him. It will be independently observable, hopefully on test gear, but for his particular box only. Or, perhaps, because his buddy observed it too, for the Swedish version of slimserver, or the SB running on Swedish mains, whatever. It the very least it must be independently observable outside his subjective perception. That means other people must observe it in a controlled setting (= not warmed up by Omega as in "here, this thing sounds much better the second time than the first, don'tcha agree?"), or measurement should indicate a difference. The particular program advocated for measurement is junk IMO - the Audio Critic guy seems to be just as bad as the hard nut subjectivists, just in the other way IMO - but I can only say that *after* I have tried the program and found the results non-reproducible, compared to the advertised operation. The only people who have been able to reproduce this 'design miss' are Omega and his buddies AFAICS - and there is enough unusual behaviour associated with one of those buddies that there is a strong suspicion they are one and the same person. Omega may have a point - perhaps there is something screwy about how his SB works on his server. But he hasn't gone about trying to get independent confirmation of his results, simply raised the stridency of his claims. Dragging in logically unrelated red herrings like how people failed to realise jitter was an issue in the early days of CD etc doesn't actually strengthen his case. How are Slim Devices meant to fix his problem if a) it hasn't been confirmed to be a problem outside his signal path, and b) neither test equipment nor other *independent* listeners can reproduce his results? He has not in any way *proven* that this is a problem for other SB users. And he hasn't gone about getting independent confirmation that it is a problem with his (or even th Swedish) SB in a particularly organized way that could be used to chase it down. The fault he claims to have clearly is not one that affects other SB users outside his circle of friends in a significant way. -- ermine ermine's Profile: http://forums.slimdevices.com/member.php?userid=12613 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
In the late 80´s One Hifi magazine here in sweden did a listening test on Digtal transports (CD players) to a External DAC. The CD players sounded much difference from each other, They fought this difference was because of the transports reading capabilities, more stable CD mechanism etc. Then they measured the "Digital stream" from the Cdplayers to see witch CDplayer was the "best reader" But during the measure all CD players had identical bitstream, all was Equal good ! This made the testers really confused, Why did they sound different ? They couldnt explain why there was a difference. Jitter... Note, i am not claming the SB3 to have high jitter or anything regaring this litte story. I think there is a more to learn in the future regarding "digital audio". we maybe not have discovered all the things affecting the Sound. When the CD was new in the 80´s it was "perfect sound forever" -Mark Lanctot This thing about streaming "flac as Wave". I don´t think Wave "sounds better" than Flac, They are bit identical. But i think streaming "flac as Wave" sounds better than streaming "FLAC as FLAC". My only guess regaring this is: 1.The Slimservers Flac Codec is better "Unpaking" the Flacfiles? 2.The CPU in the SB3 gets more stressed "Unpaking" flac vs Wave, and more increased load causing extra EMI & Jitter? And the "Wireless vs Wire". I think this has something with RF affect the digital signal on the SB3? -schatzy I have 2 old fashion isolation transformers for my Stereo. One isolation transformer for the Amp and one isolation transformer for the other (DAC, SB3, ETC) -truckfighters I have tried the "replugging mains 180°" to the SB3, but i can´t hear any difference. But i think the "replugging mains 180°" only works with analog equipment, All my equipment have "the right phase" according to my taste. I have had my new Ultramatch Pro SRC2496 connected a few days, And "is´s a keeper" !! :-) Now the sound is even better ! Wow ! :-) The SRC2496 is connected like this: SB3 Optical out Sp/dif 16/44 -> SRC2496 "use internal clock not SP/dif" & AES/EBU 44/16 -> DAC (Musical fidelity X-Dac v3) I have tried difference settings on the SRC2496 like upsampling, 20-Bit, 24-Bit, use SP/dif clock etc. But I think leaving the signal "untouched" 16/44 and "Only" reclock (use internal clock) and send AES/EBU instead of Sp/dif. sounds best. And the "Pause, power on/Off, Pause" still works...

I didn't say anywhere that omega is wrong, whatever that means. I certainly never questioned whether or not he was hearing something - on the contrary, I defended him against some posts suggesting he was trolling. I simply suggested a simple and effective test which would help isolate where the effect is coming from. The issue here, which seems to have escaped you entirely, was whether (as omega claimed) there is a problem with the SB or with SS or whether it's placebo. It's not very difficult to answer that, and until it's answered it's a waste of time speculating about what might be wrong with the SB.

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
Hello again, I am not one to normal name names but in this case Opaqueice, it is attitudes like yours that prompted me to write in the first place. Omega could have 100 or even 1000 or more people listen to his system and have the same experience that he has had. Then I or anyone else on this forum could find another 100 or 1000 or more people that do not hear it when listening to Omegas system. You can not and do not have the right to tell these people that do not hear it that they are wrong. They just do not have the ear that can hear it. If we gave them all hearing tests we may find out why they do not hear it but in that case no one can tell them they are wrong because they just do not hear it. He's not saying "I hear this, isn't that nice, let's all be happy." Also Opaqueice, no where in my last post did i say that Omega should just "be happy". I in fact think that he should be posting here to say "I hear a problem". I believe that Omega does hear a difference. I have not noticed and have connected my computer and SB3 to a friends system. This system consists of mostly Mark Levinson equipment. Now you will probably say that Mark Levinson equipment is trash, but there are a lot of people out there that would argue with you. I will not because you have your opinion and i have mine. Neither of us is wrong as far as i am concerned. What should be happening here is trying to figure out a way to solve the problem and not all the bickering from people like you saying he is wrong. No one is wrong here. Some people may hear it and others may not. That does not mean they are wrong. Omega, Have you tried a plain old fashion isolation transformer, not any of the so called power conditioners to try and eliminate any mains interference. Also mentioned here is a mystery surrounding the phase of the mains and why it seems to sound better if all of the equipment is connected in the same phase. Yes here in the US we can not normally change the phase of the mains for each piece of equipment as one side of the power is always connected to ground. In Europe ground is separate from both the voltage lines. Question to sean adams, has all the audio (hi-fi) equipment in your testing lab been connected to 220-240 volts with a truly independent ground (i.e. maybe no ground at all connected), is there a difference of the kind that Omega is stating he hears. Can you reverse the plug on the SB3 (changing the phase) and then is there a difference. How about if the amplifier mains phase is reversed. I do not remember reading if this has been tried. If it has great if it has not can it be tried so that just one more possible cause can be eliminated. I ask the above question because when i worked for Cello Ltd. (search the web if you have not heard of them) we had problems with some transformers not preforming well on mains power that was not grounded (neutral) on one side. This ended up being a problem with one small lot of transformer and the way they were wound. Unfortunately Cello Ltd no longer exists but many of us that worked there very much enjoyed the experience and the quality of the sound reproduction that it produced. I surely hope that through good and non combative discussion that this problem can be solved. Even if it take 124 pages of posts to this thread. Lastly i apologize in advance if i have offended anyone.

I had to reboot the SB3 to take care of a really 'muddy' sound. Also, I upgraded to a dual-core CPU on the PC running Slimserver and reripped most of my collection. Now the sound seems better.

hi there, just found this thread, read almost the 10 first pages and came to the 2 last - the issue still not solved. a whole wile ago I was posting a similar issue I had with the SB3. that was exactly the same thing omega is hearing. the sound is changing and is not "high-end" anymore. it sounds like digitally distorted. I don't know when and whay it happened, but it really did. Also this came up when friends were here visiting my place and my seriously listened to music. since I can remember how things should sound, I quite fast heard the change. so what I always did to bring everything back to normal was simply to unplug the power source of the SB3 and replug it. then the sound was restored to "high-end". I postet this in the end of 2006 and also sean adams replied to it. but we found no solution. I have a transporter now and no issue here. I could believe it has something to that we phase, neutral and ground here in germany (may be in sweden also)? we can plug our devices like we want into the wall sockets. and I also claim that there are sonical diffences by replugging mains 180° of transporter and my amp. but this is not an unknown fact here in germany. a lot of people are aware of the issue and there are even devices out there to detect the correct phase of the mains plug. cheers -- truckfighters | Transporter | REDGUM RGASil OCC Silver Interconnects | REDGUM RGi120ENR AMP | REDGUM LS Cable | B&W Nautilus 802 D | >>> Live musicians at the end of my room! <<< truckfighters's Profile: http://forums.slimdevices.com/member.php?userid=7852 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
schatzy - that's a very good post and yes, it all comes down to personal preferences. But what should be filtered out is the placebo effect. I'm starting to notice that no one on this forum will admit to being affected by the placebo effect. This can't be possible, that's how our brains fundamentally work - expectations can skew results and reinforce themselves. If you believe something is better, your brain will subconsciously change your perception of it until you actually perceive it is better. And it can be passed on to others too - once omega suggested this to his friends they were looking for a difference and they found it (if you're looking for a difference you'll always find one even if there isn't a difference). Subsequent listening tests reinforced this belief. (This is how Q-Ray bracelets are sold.) omega has also admitted that he finds WAV sounds better than FLAC and that wired sounds better than wireless. Both of these assertions have very weak physical explanations but very strong psychological explanations based on expactation (we expect WAV must be better than FLAC because FLAC is 'compressed' and wired must be better than wireless because it's solid, it's physical, we can touch it and has better bandwidth.) This is not to say that omega is crazy or that he isn't hearing this, he is, but his expectations might be overriding reality. This isn't necessarily negative, we're all individuals and some inherently and subconsciously place more emphasis on expectation. Expectation is so real and some of us can be so dramatically affected by it that seemingly non-sensical devices to improve sound (stones, exotic woods, raising cables off the floor, special lacquers, even foil strips or dots) can really alter the -perceived- sound for certain individuals, and the only physical explanation for it is that it alters their expectations. If it does alter the perceived sound, then it's money well-spent for those people. Who are we to judge? However, if those individuals insisted that others would hear the same effects they would have to prove it in a way that would ensure their expectations aren't skewing the results. The SB designer himself cannot see a physical explanation for what omega is hearing. omega is surely hearing it, and in fact his brain is reinforcing this each time he hears it - the SB will probably never sound quite right to him now. In order to fix it though, Sean Adams must find what is wrong, and he can't find an electronic explanation for it. So it won't/can't be fixed because nothing has been discovered to be inherently wrong with every Squeezebox out there. Extraordinary claims demand extraordinary proof and the burden of proof is on omega. Sean and many people here have an immense interest in making the SB sound as good as it can and if a physical defect were to be be found they would be right on it. But a physical defect hasn't been found yet. I'm pleased and slightly surprised that omega is taking this very well and still being civil, but it's also apparent that omega can't admit that maybe it could be placebo. His problem would be fixed if he could prove that it was not. It's great that he's still interested in proving this, because this is the only way to get others to fix it - to show that his expectations are not influencing his reality and that the problem can be readily and repeatedly perceived by anyone. -- Mark Lanctot 'Sean Adams' Response-O-Matic checklist, patent pending!'

You are of course right, if Mats perceives a difference, he does infact perceive a difference. But the title of the thread is "Design miss in SB3 digital output?", so there is a claim that others should also be able to hear the difference, and that it might even be a result of some technical error. To make this claim you will have to be able to prove that there is infact a physical difference in frequency and amplitude of soundwaves travelling from the speakers, which could be easily done with a blind-test. /Brjánn -- brjann brjann's Profile: http://forums.slimdevices.com/member.php?userid=12214 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
Let me start by saying that I am new to the forums here. I have found lots of very helpful people post to these forums in all categories, and have made my purchase of two SB3 much more pleasant and easy to deal with. And thanks to all of you. There is one thing that disturbs me though, and that is the negative attitude of some of the posts in this thread. (And I have read all of them). I will not name names but i think most of you will recognize who you are. Now let me put in my 10 cents here. (ok maybe 25 cents with the length of this post) Merriam-Webster Dictionary au·dio·phile Function: noun: a person who is enthusiastic about high-fidelity sound reproduction high fidelity Function: noun the reproduction of an effect (as sound or an image) that is very faithful to the original With the above stated I do not know of any test that can be administered to any one or multiple individuals that will prove if they are an audiophile or not an audiophile. All of the individuals that have contributed to this thread are correct. At least in their own mind an that is the only thing that counts. Being and audiophile can only be self proclaimed. Two of my neighbors are self proclaimed audiophiles as I am myself. One of my neighbors has over $300,000.00 (three hundred thousand dollars) worth of equipment in his home. The other has about $1000.00. I personally have about $4500.00 worth of equipment. Can I hear the difference between the three systems? I will answer that with a resounding YES. Can both my neighbors hear the difference? Again a resounding YES. The only requirement with being a self proclaimed audiophile is that you LOVE music. All the tests in the world that use electronics equipment to judge the True Sound of a audio system are there for the unknowing individual. I mean that an amplifier can boast about its low THD or its Power Output, or a test can show there is no difference in the digital signals, but the reality of the matter is that every one of us that listen to it will hear it differently. I have worked for some of the best known audio equipment manufacturers. I have been in some of the best recording studios in the United States. All of them great experiences. The real test of an audio system is for it to sound as close to the original source material as it can. If that means the recording was done on The Esplinade in Boston, MA, USA, then I had better hear some of the crowd and street noise in the recording. If it was done in the studio then it had better sound just as it did when I was actually there listening to it being recorded. I know of know system that is perfect in reproducing that sound exactly. But I can say this. I have listened to a recording from a time when I was present for the recording on my system and both my neighbors systems. None of them sound truly like standing there in the studio. You may ask which one sounds best? It may be obvious that it sounds closer to the original on the very expensive system. But what really matters is that we all enjoyed the music, the conversation about that time in my life and had a great time listening to music. My neighbors and my self can afford what we have. Yes, two of us are a little envious of the one with the very expensive equipment, but if I had that kind of money I probably would spend it on other things any way. We should all rethink sometimes before we speak or type. If Omega thinks there is a difference between the first track played and the second played and that it makes a difference turning if off and then back on that is his opinion and no one should or has the right to tell him he is wrong. That is how his ears hear it. Maybe mine do not but that does not make omega wrong. One more comment before I go. With the advent of the iPod and other portable music players we have a generation of new music lovers that may never know what it is like to listen to music on a system with Audiophile Quality. And I know most of them will never know what it is like to stand in the studio with the likes of Buddy Guy, Mariah Carey , Sting, Muddy Waters, or many others. But my feeling is if they enjoy what they are listening to great for them. We should all be glad that music is a part of our lives because there are parts of this world we live in where humans do not get to listen to music only the cries of the poor and starving.

However, I think that identifying the source/method is an unnecessary and overcomplicated step. You simply need to repeatedly be able to detect a difference when there is one, and no difference when there isn't. Identifying which is which is not required to prove that the two cases are different, and trying to do it introduces a whole new set of perceptive errors into the experiment. Once you have established a difference, you can then set about trying to identify what that difference is, and whether one case is an improvement on the other. -- Patrick Dixon www.at-tunes.co.uk Patrick Dixon's Profile: http://forums.slimdevices.com/member.php?userid=90 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
Hi all! First of all I think this a wonderfully interesting thread, and hope I will not be deleted. Reading it I've thought about a few things that I'd like to comment, excuse the length, but here are my 10 cents... Here is an interesting link: http://www.wired.com/science/discoveries/news/2006/02/70179 I think this gives us a pretty good idea about flame wars start. In 80% of the cases, we think that the readers will correctly interpret the tone in our text-based messages, in 50% of the cases they actually, in 90% of the cases believing to be correct. I personally think that both Sean and Mats have been pretty civil throughout the thread, and completely disagree with those claiming that the SD-staff have in any way been exceptionally rude. But, I could of course be misjudging their intended tone... Moving on to the placebo effect. I does seem that Mats hasn't quite understood what that is. The placebo effect in this case is not in any way an effect of fooling yourself that you hear something that you actually don't. It's simply a phenomenon of how the brain processes incoming information, what information is "picked up", and what information is discarded (actually dimensional, not dichotomous). This way of functioning is totally necessery for the brain to be able to distinguish between relevant and non-relevant stimuli. For instance, if you are having a conversation with a friend, while others are talking beside you, you and your friend will actually "not hear" what the others are talking about, that is give their verbal sounds verbal meaning. In this case you would say that the sounds of your friends voice is "clearer" than the sounds of the others speaking. This is a "placebo effect", but no one would say that you are making it up, because you actually can't retell what the others are saying. Another thing with the brain is that is constantly seeking information about that indicates that something "important" is happening. That's basic survival instinct, things that are important should be attended to so that they can be dealt with properly. As things become more important they are also more hightlighted so that attention is more readily focused on them and decisions about what to do can be made quicker. This means that stimuli (like sounds) that _could_ be of the important type, are detected and highlighted so that we can act. If you're expecting a phone call from a girl you would like to date (important!) and listening to music on a high volume, you will constantly be hearing the phone ringing, because sounds in the music that resemble the signal of your phone will be interpreted as such. It's impossible for us to consciously separate real from fake ringing tones, the meaning of the sounds that the brain adds is the only source of information we have! The thing about humans is that we're able to add "importance" to almost any stimuli. If it is important that my new stereo sounds well, any information that can be indicative if this or the opposite will be highlighted and perceived as more audible. So, expecting the sound to be different when you use two different methods of pausing the SB will infact produce different perceptions, your brain will highlight different properties of the sound. To test if Mats experience is a result of selective processing or not, no fancy testing equipment is required. As has been pointed out, he simply has to prove in a blind test that he can more often than chance will accurately say what method of pausing was used. The blind test that Mats performed wasn't that good for a number of reasons (e.g. too small n, dependence between trials), but it's simple to produce one that is. I suggest the following protocol: * Mats is blindfolded, and preferrebly listens to the music with headphones. * A neutral person roles a die, if the result is odd (1,3,5), method 1 us used to pause, otherwise (2,4,6), method 2 is used. * It is important that Mats won't be able to draw conclusions from the time of the pause, therefore the neutral person should press the "play" button at a fixed number of second since pausing the music. * 30 trials are made, and for each trial the number on the die is noted, the method used, and whether Mats correctly identifies the method. Then post these data on the forum, and a simple chi-2 test will reveal to what degree we can be certain if the sound differs or not. Note that being right in only 70% of 30 cases indicates a 97% chance that Mats is correct, so 100% identification is not necessary. I don't think it's unfair to expect Mats to perform this blind trial after all this fuzz, since it is easy and would demand considerably less effort than contacting people with fancy testing equipment. /Brjánn -- brjann brjann's Profile: http://forums.slimdevices.com/member.php?userid=12214 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 __

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
AC3 and DTS are compressed buffered formats. Jitter has no part whatsoever in that equation (hint, -buffered-). Think about it, if you change even one byte in a compressed zip-file and then try to uncompress it. What happens? And the term pass-through doesn't really apply here either I think. The files I linked to are in WAV-containers, you can burn them as regular Red Book CDs (of course without a decoder you'll just hear static). -- bosco bosco's Profile: http://forums.slimdevices.com/member.php?userid=12538 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I tried this with three different recording techniques - into my laptop's line-in, into my windows desktop's line-in, and using a Tascam USB microphone interface I have. None of those recordings exhibited the problem you're having - in all cases there was some noise in the difference file, but it was quiet, had a pretty white spectrum, and just sounded like static (except for the Tascam which was introducing some high-frequency crap for some reason). You might try the laptop - even if it's mono you can just record one channel. Not ideal, but might be quieter (for me the laptop made the least noisy recording).

If I understood his post, he IS hearing a difference even when both files are recordings of the same track from his CD player. So there's something wrong with either audiodiffmaker, the recording process, or his CD player. That has to get sorted out first.

However, my ears are what I listen to music with, so that is how I evaluate products related to listening to music. This seems reasonable to me. I often get to a point in an A/B listening session where everything sounds the same, at which time I grab a coffee and chill for a while. If there are differences I can normally hear them, often quickly but sometimes less so, and if, over a few sessions, I really can't tell the difference then I don't get fussed about it, buy the cheap or pretty one. Conversely, with difference testing there is all sorts of analysis you have to do to prove the audibility of differences, and all you do is prove the testing equipment rather than the music experience. If you find any difference, it gives you no indication of what is best, and if you don't find a difference, the equipment might not be as sensitive as your ears. Pointless.

I wonder - do you also find it easier to discern differences with the volume on your amp turned all the way down? Or maybe you listen to your CDs by holding them very close to your ears? After all, the ear is a magical device that's far more accurate than any electronic gear, right? So why not remove the CD player and amp and speakers - they just get in the way. Look - audiodiffmaker is like turning up the volume on the differences and turning down everything else. Once it does that for you, you can USE YOUR EARS to listen to the difference file - and guess what, the differences are easier to hear, just like it's easier to hear louder sounds than softer (at least for normal human beings with non-magical ears), or to hear a quiet sound when there's no loud one to obscure it. And if you want proof it reveals differences that the ear can't hear, that's very easy. Just take two identical files and run one through a filter that distorts phase. Totally inaudible (except in extreme cases), but the difference file will reveal it easily. -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
This test takes two analogue audio signals and subtracts them. The resulting file is an upper bound on any difference - in other words any real difference between the two files will be smaller than the result. You can then listen to the differences without anything masking them. You can turn up the volume, look at the waveform, etc. It's an EXTREMELY sensitive test - much more so than human hearing in an A/B comparison. For example phase differences will show up very clearly in the difference file even when they were totally inaudible in the original sound. If a negative result on this test doesn't convince you, nothing will and there's no point in doing ANY test. It's also far easier to do than a proper blind test. It's off topic, but you claim to have done blind tests for CDs versus CDRs - can you describe the test setup and results in detail? -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I think tests like that will not result in showing a difference. But i dont think that should say that the difference is not there and therefor must be in the mind. Because the difference between that cd and cdr looks like so much simulair to this effect. And, as far as i know, there is also not a technical explanation in difference between cd and cdr. Technicians also say (and honnestly believe) that there IS no difference and all the diffrence should be in the persons head... But with cd an cdr i can prove the difference in blind testing, over and over again... But the technicians still believe it is in my head... But, escuse me for bringing this cd versus cdr back in this topic... It's (probably) not connected to this problem... but as i say again, those test will probably not result in differences, but... still it can be there.

-JimC Quote: "You've _modified_ a Squeezebox such that you claim to hear a difference, and then call it a "design miss" but go on to state that an unmodified SB3 would probably not exhibit the problem." The only Modifications that i have to my Squeezebox is: 1. A Custom Linear powersupply. (Hammer is still running on the original) 2. A Digital isolation transformer on the Coaxial Digital output on the SB3. (Both me and Hammer have this Modification) When i discovered the problem or "effect" my SB3 was i original state.. Only the Custom Linear powersupply. I still hear the same effect through the unmodified Optical output on the SB3... I only tried the "digital isolation transformer" Modification to se if that fixed the problem... I was "satisfied" with the optical output in the firstplace. When i talked about remove the "isolation transformers" & "power cleaners" i ment the AC current 220V/50 HZ feeding my whole Stereo. Not removing the Digital isolation transformer inside the SB3. I still hear the same effect through the unmodified Optical output on the SB3... And is a External DAC a Modification ? Yes i think i propably not going to hear any differance or have much more difficult to distinguish between "good" and "Bad" sound. Running through the analog outputs on the SB3 and removing the "isolation transformers" & "power cleaners" (AC current 220V/50 HZ) And if i remove my Elac CL 4Pi Plus (A universally applicable omnidirectional tweeter) "Then my problems will ge gone". I just tried to get a point in the previous post. Not all people is running with an External DAC etc and probably and not hearing this effect.

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
To Omega & co First I most tell all, I do not have a SB3 so I not able to hear how it sounds and I not able to verify your clam. But as I see/read it, you and your friend have both a heavy modified SB3. This it self could be a problem as you not able to conclude that is the SB3 that has the fault. You also report that you think that without a isolation transforms, filters and so on you would have difficulty hearing the difference. Please do this test as a blind test for another person the you self/friend, this should be easy. And report back you discovery. In your setup, how can you be sure that there isn't a part of the system that falls, it could be that it just can't stand to have the same piece of music played twice with out a power off. It could be that the DAC have going in saturation/fault mode or soo In the pause situation not power off. The electrons could be jammed in the cables you could try to change them all. To all please don't take this selection very seriously :-) I not a believer Maybe Sean can answer this; during a power off situation are any part/circuits of the SB3 actual power off. I thinking in the non audio part, display control, wireless interface, main cpu and so. and in what state, are these circuits in a pause situation? It could be that something could add noise or change the phase in the music signal after a pause in the audio signal. All test should be blind tests: What happens is the first track played last a fraction of a second how it the next track then perceive? Try during the first good track to power off and on various parts of your soundsystem, DAC, preamp, poweramp. what is the perceive sound like Do you have the possibility to use another source to your extremal DAC like a cd player? Then try the same test. What happens if you use a pure tone instead of music? try both a high and low frequency tone My biggest concern is that you stop/have a break in the music. To my knowledge this alone can be enough for some to report that the heired two sounds (this is in a pure tone test). I can only suggestion you make a recording of the two situations and publish the result to this forum. My last comment please accept, that some people can't hear what you hear. if your not sadified with the SB3 buy another product rebuild it like others have. Maybe this product is just not high-end enough for your ears. regards Daniel -- danielu danielu's Profile: http://forums.slimdevices.com/member.php?userid=12424 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

You can't _measure_ any difference so far but still insist there is a difference. A bunch of people you asked to listen for a problem believe they heard the problem. You don't perform your listening tests in a way that would exclude awareness of the test condition. But there's *no* chance that this is a perceptual problem... it simply has to exist because you heard it. Okey dokey. I'm done...

This will be tricky to "compare" as you'll have to match starting points, but as long as the file contains the same segment of music, it should be straightforward. You could also post them here for other people to help you reveiw. This test tells about the digital output from the SB3. 2. Using any analog recording mechanism (with reasonable fidelity and dynamic range), record the "good" and the "bad" audio, again using the same section of music. Use AUDIODIFF to compare these. This second test is for THE REST of your system. In other words, if test 1 shows no difference, but test 2 *does* show a difference, the problem is occurring somewhere in the process of digital-to-analog conversion and/or turning the analog signal into audible frequencies. > Hammer and I are not so good in the "Digital Domain" > We need help from someone who has the "know-how" and the measuring > tools for this.

While it would be good to verify that the digital stream out of the SB is the same in both cases, that's not what audiodiffmaker does. It compares two recordings of the *analogue* output of something, say your DAC. And I'm pretty sure that just about all soundcards have an input - otherwise you couldn't use a microphone, for example. -- opaqueice opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
ganjastone, Thanks, I appreciate your perspective, and I agree that I personally need to strive to set an example for level headed discussion in this forum. However, I respectfully believe that you have misinterpreted my position on this. I accused Omega of trolling because of the _manner_, not the subject of his post. Wikipedia defines a troll as: -In Internet terminology, a troll is someone who intentionally posts derogatory or otherwise inflammatory messages about sensitive topics in an established online community such as an online discussion forum to bait users into responding- If you think I made the wrong call, then we shall have to agree to disagree, because I stand by that assessment based on the deliberately inflammatory language that Omega has used throughout this thread. If you think that it was wrong of me to merely _say so_, even if it _was_ a deliberate troll, then again I disagree. The S/N ratio in this forum is not going to improve if we all tolerate (and even encourage!) trolling. As respects the actual claims that were made: please read my posts on pages 6, 7, and 8 where I really did my best to address Omega's claims and to suggest a constructive course of action. You will see that I did in fact suggest some very simple tests that Omega could have easily performed which would have helped to elucidate the problem. _He_ refused. What else can I do? I could not reproduce his problem, I have already tested the product extensively, and I could think of no theory that would support his claim. As several others have pointed out, I would be the first to devote my full attention to solving such a bug. But first we need to identify what we want to fix. Finally, I believe that a disproportionate share of the dismissive/mean language in this thread is being attributed to me after the fact. I encourage you to re-read ONLY my posts from the beginning of this thread, and to separate the trolling issue from my analysis of his actual claims. I did not question his claims because I thought he was trolling. I questioned them because I believed him to be mistaken.

Actually, Sean's done a great deal of testing, both simple and complex, on the SB3 and the Transporter. He's never once observed the problem Omega spoke of... since it hasn't been seen before, some repeatable, measurable tests were proposed. None of them have been tried yet, or at least no data has been provided from the tests. Instead of measureable, repeatable data, we got a lot of "all of my friends hear it too!" responses. Interestingly, the results from the measurements Omega had made externally showed no difference. Here's his quote: omega;213761 Wrote: > Hi Craig! > > We only used Inguz "pink noise" source during the measure. > I am not using Inguz DSP plugin. > > I got the result from the measurement, but this shows "nothing". > This measure not measuring "Phase" etc. Early on, Sean suggested a placebo effect as one possible cause, which immediately started to reduce the signal-to-noise ratio on the thread. It shouldn't have, since the placebo effect has been proved over-and-over in a number of disciplines. In fact, even groups of people can suffer from it (a severe form being mass hysteria). At this point, since no one has provided measurable differences of audio before and after, and the external measurements showed no delta, I think the safe hypothesis is just as Sean orginally proposed: "placebo effect". If there's repeatable evidence to the contrary, I'm sure Sean would dig into it and try to identify the cause with an eye toward solving the problem. > Your attitude might even cause me to run a stupid on/off pausing test > :) > > I btw, am not a troll, but a true real happy SB user from Israel I tried it, too.

Re: [SlimDevices: Audiophiles] Design miss in SB3 digital output? or Slimserver problem ?
Dear CEO, I truely admire your products and have 4 SB and planning on buying a Transporter soon. Being a "heavy" SB user and audiophile I am sure Omega and co. are doing something wrong. Said that, I totally agree with adamslim and I think your attitude is both insulting your users and even suspicious. I, as a former R&D manager and currently as a Director of a Product, have a lot of interaction with customers. I would never ever think of answering a paying customer or even someone that I suspect is trolling my forums in the same manner you did with Omega (especially not in a public forum, even though I hope this was cinical). Not only you're not suggesting any help solving his so called problem, you accuse him with different accusations. You don't even think of running a simple test, instead you suggest he provides "scientific" proof (my words not yours). Your attitude might even cause me to run a stupid on/off pausing test :) I btw, am not a troll, but a true real happy SB user from Israel -- ganjastone ganjastone's Profile: http://forums.slimdevices.com/member.php?userid=3122 View this thread: http://forums.slimdevices.com/showthread.php?t=36503 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

Out of context? Agreed! However, I do think that, as CEO of Slim (or whatever nowadays!), you need to rise above how people phrase what they say, for two reasons: 1 - some are foreign and do not express themselves well in English 2 - these are people who have paid money to you. Don't be sycophantic, but do default to validating their position (not necessarily their claim - i.e. see how this would make them unhappy as paying customers if they were right, not that they are actually being reasonable or correct) And yes, it is clearly unreasonable to expect them to perform extensive testing prior to posting here. Part of the point of a forum is to be able to wave about completely illogical and unsubstantiable opinions - some people like that. Encourage them to do the test in a more controlled fashion. Why not offer people a free Squeezebox if they can find an acoustic flaw that results in a change to SlimServer or the firmware? Rather than denigrate them for not doing rigorous scientific testing, why not bribe them to do so? It'd be cheaper than doing it yourself!

The original post was not a mere inquiry or observation. It was a (very successful) troll.
