Re: [SlimDevices: Audiophiles] An interesting article on vinyl vs digital.
Indeed, I agree, overall a nice article. I like that little embedded video talking about the limitations of vinyl mastering. Indeed that RIAA curve is nasty and the old LP technology is full of compromises we have taken for granted with the freedom of digital. (Makes issues like jitter laughable!) I think the main message about reminding the vinyl lovers that -LPs are less accurate- than a -good -CD is an important one that is quite clearly based in fact. Even though I do not own a turntable any more, a number of friends have bought TT's in the last 3 years and I've had the pleasure to listen to some excellent vinyl rigs as a result. They can sound very good and obviously the experience of the physical object, playback ritual, and large artwork can certainly provide a different (and some would argue richer) experience.

Surely you know we would try our best to keep the identity of the tracks hidden as best we could without invalidating the test altogether - fine line there but I think we did a good job... Therefore, indeed, it is possible for the null test to show unexpected results but that depends alot on other factors. Great to see the responses so far!

JJZolx wrote: Most audiophiles think ABX testing is worthless. Why would they want to ABX these samples? It's like telling an atheist to try praying to some god or another and seeing if they get any results. I'm also not sure what exactly the point would be of encoding them both at 24/96 when many people think that the 96 kHz encoding itself is detrimental to sound quality. That includes many audiophiles who prefer 44.1 kHz. Good luck with this test. I imagine you'll get quite a few people who are already convinced that hi-res audio is a scam and will come back and confirm to you there's absolutely no difference. Wow... When did many audiophiles prefer 44.1kHz and think 96kHz would be detrimental!? Monty's well known page about 192kHz makes sense and certainly you can get some intermodulation distortion with that much overhead; but I think most reasonable audiophiles / engineers would consider 96kHz about the sweet spot for maintaining high quality and reasonable file size. The reason to keep at 96kHz is precisely because that is the sweet spot IMO and most DACs measure exceptionally well with that sample rate these days plus the effects of digital filtering is reduced compared to 44/48kHz given that extra octave. Well, as Wombat states, I do have a little more faith in humanity :-). My interest is *not* as a proof to the audiophiles. To be honest, the faithful are a small percentage and as you indicate, unlikely to change (granted I know I've converted a few of them to the dark objective side in the last year!). However, my sense is that those guys are diminishing as a group. Each year that goes by, I think their influence will diminish for many reasons I won't go into here. I'm more interested in opening up a discussion and an opportunity to the folks just starting to get into audio and the whole idea of high-resolution. For now, the ship has sailed. The test has begun, and it's great to see the detailed responses people have entered already. I hope this provides an opportunity for those who are not as technical to experience the difference for themselves and contribute to a body of data which can at least try to answer whether larger file size, and higher expense would be audibly beneficial. --- Yes, the reason I would not do an Internet 44kHz vs. 96kHz test is that it's way too easy to spot the difference. I have some faith in humanity; but not *that* much :-). The only way to try something like that is with controlled testing in one's home / listening room with test subjects.

Re: [SlimDevices: Audiophiles] TAS Reviews new Sony HAP-Z1ES player
Great discussion guys... I agree with Mnyb around the topic of measurements. Diffmaker comparisons which null out pretty much tells us if there's any difference at all. As for the idea of needing more and fancy tests, well, of course there could be things to try... For example, on my blog there's a suggestion to try 2fs (ie. 96kHz) jitter tests as opposed to the standard 24-bit/48kHz one I'm using currently. Hey, I'm sure that will show significant differences between DACs at 24kHz! Maybe a dog/cat can appreciate jitter up at that frequency... The poster suggests that this makes an audible difference with 24/96 music. I already have the test signal to do this but have not tried yet so will withhold judgment. Ultimately, it boils down to audiophiles (and the press) accepting that if we're really going to get anywhere, double blind listening tests are essential. Yet no magazine does this. If anything, audiophiles look for every possible angle to debunk or invalidate testing which is acceptable to every other scientific discipline I know of that deals with human perception or biological effect. Show me double blind test results where listeners are able to discern differences between DACs, cables, etc... AND where standard measurements cannot explain these differences. Then we can at least consider what other tests need to be devised because then we can say with some certainty that we're missing something. --- Ralph: I think you're right about the assessment on JA. While I appreciate his work on objective measurements, there is at times a clear bias as to how he interprets the results. Mediocre results from an inexpensive / not well regarded brand will get used to explain inadequacies. Mediocre results of expensive / well regarded brand / well advertised products often gets tossed aside as I can't explain why Mr. Subjective loved the sound... Perhaps it's exactly because it measures like this! (For an example, have a look at his conclusion of Audio Note's CD-4.1x CD player - awful noise floor, waveform reproduction, even terrible jitter.)

Re: [SlimDevices: Audiophiles] TAS Reviews new Sony HAP-Z1ES player
Good discussion boys and I don't think there is a need to fight over this either... Whatever works is fine. High-res formats are already capable of retaining accuracy enough for anyone's needs and the limitations of the recording studio. The issue here is nothing even close to measurable and audible differences between digital vs. vinyl! I agree with keeping the original modulation technique - Channel Classics albums started life as DSD with minimal studio manipulation I am told, so I'm happy to keep a copy as DSD files in my archives since that's the best they get. Based on objective measures though, I feel no harm was done when converted to 24/88 for the DACs that cannot handle DSD so I have that version on my LMS server as well (the PCM version also has the benefit of digital room correction). I think Mnyb has a point with too many formats though... It just fragments the market, confuses the consumer, and creates unnecessary disappointment. Despite the advertising push into high-res HRA, I truly feel that there's just not going to be much of a market because the average consumer will not hear a difference and move along... This is *nothing* like the obvious benefits of DVD vs. Blu-Ray if people are searching for an analogy. With a small consumer base (ie. obsessive audiophiles who want the best version of their favourite album), it makes sense to aim for standardization.

I don't know if I am going to actually have 192/24 music -- right now I only have one album here. Since the difference between 192/24 and 96/24 is ultrasonic, I don't see a need here. What I was really surprised about was the measurements of the Analog RCA Connects: http://archimago.blogspot.ca/2013/05/measurements-analogue-rca-interconnects.html I figured there would be an audible difference and maybe to some it would, but based this, I imagine that for most, there isn't an audible difference. Overall, I am very happy to know scientifically that as long as you have a shielded cable, that's all you really need and thus no need to waste money on cables. Much appreciated the advise to read Archimago's measurements. A pleasure, dhallag. Many moons ago, I was very much influenced by purely subjective reviews and suggestions. I remember being entranced by the green CD pen, captivated by the theories around Peter Belt's remarkable foil, and all manner of audiophile tweaks... Yes, including the various cables; making and testing many of my own. But I did take to heart the suggestion to find out yourself during one of these forum debates - but of course not as the guy suggested (ie. spending ridiculous $$$ on buying and listening to crazy expensive power cables, USB cables, and the like to gather experience with the esoterica - that would never settle anything!). The blog in many ways is a personal testimony of that journey out of a purely subjective mindset using what I had around the house (an unused E-MU0404 as ADC) and software freely available on the Internet. While I don't claim authority in definite answers based on just the tests, I do insist during discussions and debates that the other side show me what evidence they have beyond vague impressions. I try to keep my mind open and am totally willing to change my viewpoint if there is reason and evidence. Now as for the Touch - yes, amazing technology for the price! Bar none the best value for the money I have spent on audio gear. The thing that really blew me away was when I tested that TosLink output with EDO firmware and discovered it worked with my ASUS Essence One DAC at *24/192*... I had never come across this before and I think this speaks to the quality of the parts and the design. Enjoy the hobby!

Re: [SlimDevices: Audiophiles] TAS Reviews new Sony HAP-Z1ES player
Interesting comment Firedog. I have not heard the Sony but will certainly give it a try when I'm next at the dealer. As one who has been buying SACDs since about 2001, ripping my SACDs since 2012, having played with PCM -- DSD conversions like with JRiver upsampling, and have some experience with the whole PCM -- DSD conversion process (see the 'post on my blog this week' (http://archimago.blogspot.ca/2014/04/analysis-comparison-of-dsd-encoders.html)), I personally do not feel DSD adds anything special to sound quality. A well done 24/96 (especially multichannel!) is as good as anything I've heard from DSD over the years... As suggested by the conversion results on the blog post, I'm quite happy with 24/88 conversions of DSD64. Accuracy is excellent so the math is good! In fact, mainly for convenience and space savings, I only bother keeping about 20 of my SACDs as DSD on my server mainly as demos for friends who want to have a listen. The rest I keep as 24/88 for streaming to the Transporter. I suppose one could argue for the high sampling rate of DSD (temporal resolution of things like impulse responses) and filter difference, I'm not one who has experienced or believe that they make much difference ultimately compared to a good upsampling linear phase PCM filter. firedog wrote: ... BTW, if you haven't heard a native DSD recording of acoustic instruments, you might be amazed at how good it sounds. I have a couple of native DSD orchestral recordings that simply are the best sounding recordings I've ever heard of a symphony orchestra. Period.

Plus the songs load faster so I love this change. It's got a 1.6Ghz CPU with 512DDRIII so I believe that is powerful enough, yes? Looking at the QNAP site, it looks like the typical processor they use is something along the lines of Marvell's Feroceon 88F6282 at 1.6 GHz. This is a single core ARM processor. To get a speed comparison, if you look at the Linux BogoMips rating, this processor gets something like 1600. This is equivalent to about a Celeron M @800MHz. As you can imagine, that's not a high level of performance. Good to hear that 24/192 transcoding to the Touch worked ok through the powerline though which is good. However, it looks like there's not much extra headroom for simultaneous streams. You could also try taking out the Receiver and use SqueezePlay on the computer as a simulation of a second Touch to check for dropouts.

Having had some surprisingly immersive 2 channel experiences, it seems multi-channel is the wrong solution to a problem of flat-sounding 2 channel systems. As with everything, YMMV applies. Although a fantastic stereo recording with an excellent system could portray a great surround image, it's certainly not the same experience for me compared to discrete surround. With the latitude for more precise imaging and freedom from being at the sweet spot (and able to move/turn one's head without the 3D imaging collapsing!), I'd say it's a solution that outstrips the capabilities of 2-channel sound. Maybe not ideal, but the best one we have currently... As a practical observation, during demos for friends/family, I don't believe anyone has requested to go back to 2-channel stereo after hearing a good multichannel mix over the years. And of course, there are many multichannel mixes I detest and would prefer the stereo mix (eg. Neil Young's Harvest). Archimago's Musings: (archimago.blogspot.com) A 'more objective' audiophile blog.

Could get expensive depending on media costs! 4. Play off your computer's surround analogue outputs to surround receiver/preamp - sound quality compromised with most motherboard sound but one could buy a better sound card. 5. (Best solution) Play off computer HDMI output to a surround decoder/receiver. This is what I do. foobar and JRiver recognizes my Onkyo receiver over the HDMI cable and will play the multichannel audio natively. I haven't bothered to author DVD or DVD-A for years. Blu-Ray burning would be a waste since even a single layer disk can store 25GB; too much for just audio unless you have something like 10 surround albums you want on 1 disk. The only thing I have not tried is playing multichannel DSD through my receiver which I think is not a good solution since almost all audio processing like bass management happens in PCM so a conversion step from DSD - PCM is almost assured.

Re: [SlimDevices: Audiophiles] Is this some kind of Sony magic?
Guys, I feel like we're in some kind of audio time warp... We rehash PCM 24/192 for the on-line world (DVD-A -- HDTracks) starting ~2009 We rehash DSD64 for the on-line world (SACD -- DSD64 downloads) starting ~2012 We now rehash the *super tweeter* in concert with the hi-res experience in 2014... I have a sneaking suspicion that this will all commercially fail much faster than the 1st time round in the early 2000's. At least back then things *felt* new with the hi-res formats giving genuine excitement and early adopters had a chance to experience it all for themselves. (Maybe Pono will be the poster child come end of year?) The only thing left after this round of push into high-res to squeeze as much as they can from the consumer with old music is to bite the bullet and admit all that really matter is how well music is recorded and mastered in the first place. Maybe then we can get somewhere fresh with truly high quality audio rather than DR7 HDTracks releases in 24/96... Of course I could be totally wrong and by this time next year, everybody and their grandma will be talking about how great Pono is, Neil Young becomes a billionaire, and Blue Coast Records expanding their DSD servers with audiophiles clamouring for more!

JJ77 wrote: ... Just listened to some Flac Masters from Linn /records at 44.1Khz 24bit. Although these are very good, The DSF converted files do sound more detailed and live to me (again they are not the same songs/recordings so very subjective.). I can really see where you have to decide on your own what is the best sound for you. I do like the DSD (DSF) files as you can convert them to any format you want and they sound good. If the conversion software develops to a higher degree, then possibly the DSF conversions themselves in the future will be even better?? Welcome to the forum JJ. As you know, there are many opinions out there in audiophile land. Many variables are of course involved in all of this that it's often difficult to separate the wheat from the chaff as the proverb goes. As a hobby, it's fun to explore the variables and come to one's own conclusion on things... I like keeping things as the paraphrase from Einstein goes as simple as possible, but not simpler. And I personally find that having some objective analysis keeps me honest with myself and what I think I hear. This is especially significant when we're dealing with directions the industry pushes on the consumer especially these days when what is offered as improvements enter into the realm of the most likely imperceptible. In this regard, I would suggest the good ol' rules of thumb in terms of sound quality and what affects it: Good speakers/headphones (hard to tweak these) Good room (potential to tweak or correct for) Good music (what it's all about!) I believe that essentially everything else makes a difference but I would advocate not wasting too much time on it if it takes away from musical enjoyment. Which CD player/DVD/streamer, DAC, amplifier, DSD vs. PCM, sampling rates above 44kHz, 16 vs. 24-bits, cables all have a *very* steep slope of diminishing return (especially those cables!) to the point where there's really no reason to get too excited over the stuff. Standards are high these days such that one doesn't need to have a millionaire's system to feel that you're not missing out. Furthermore, much of this becomes purely subjective at some point as well - for example solid state vs. tubes. Even if one hears a difference, the value of the difference is usually idiosyncratic to the listener - not really worth arguing about unless there's an agreed-upon sense of what is to be achieved. Regarding the DSD sound and conversion. Yes, a good DSD recording sounds good whether native or converted to PCM. There are volume level idiosyncrasies with DSD conversion such that one has to be careful that the conversion does not lead to clipping (this was an issue back in the day with the first batch of SACDs). Along with that is what to do with all that high frequency noise created by noise shaping. Some converters like Weiss Saracon (professional software, expensive) will characteristically filter almost everything 40kHz which means there's no benefit to PCM files over 24/88kHz (a good example is Channel Classics - do not buy the 24/192 files because there's nothing over 40kHz). Other software like the free KORG AudioGate will retain more of the ultrasonic content so 24/176 or 192 will look like there's stuff there, but it's noise. From my experience with JRiver, it's more like AudioGate in this respect. I don't think it matters for the most part unless high-frequency content causes intermodulation distortion with one's speakers or strains the amplifier into oscillation. Most DSD DACs will impose a low pass filter so I do appreciate Saracon for imposing the filter in the software conversion itself. We must remember that there are limits to DSD, just like any other format. Many folks (including myself) feel that there's no point to DSD64 (current typical 2.8MHz sampling rate) simply because technically it isn't significantly better than 24/96 PCM; and is probably less accurate. To convert from DSD64 -- 24/88+ PCM will lead to small rounding type errors. Furthermore, if you have a DSP process in there like room correction filters, these do not function natively in DSD so that conversion to PCM will have to happen. Bottom line is that the purported benefits to DSD don't seem to be significant when compared to the limitations. Companies would like to sell you a new DAC for the DSD feature of course! It's just one of those things that gets argued upon ad nauseum but unlikely anyone ends up feeling satisfied with. The fact that you liked the JRiver conversion without any tweaking is good enough evidence to suggest that the PCM version moves you.

JohnSwenson wrote: I was actually IR laser light, this is a very important distinction. CD players (NOT DVD players) used IR light to read the pits, the particular green ink had a strong absorption to the IR wavelength used by the laser, which did cut down on some leakage coming out of the edge of the CD. That DID allow some CD mechanisms to track better, cutting down on the electrical noise generated by the tracking circuits. Note that in order for this to work it had to be the right ink that had good absorption to IR, not just any old marker pen. Many tests were done with the wrong ink. Now fast forward to DVD players used to play CDs (which is now predominantly the case). The light is now red, not IR, the absorption characteristic of the ink is different to red than IR and the whole optical system and tracking mechanism is VERY different. I won't going into all the gory details but the upshot is that most DVD mechanisms have a very different response to edge painting than the original CD mechanisms did. Not that there is NO response, but it is different. The spectrum of the noise is quite a bit different due to the very different tracking systems. The upshot is that edge painting can still cut down on noise with DVD players, but how much is fairly variable depending on the specifics of the mechanism. In addition the noise that is being affected is quite different, which means it will most likely be detectable by different people in different ways than was the noise from the CD only player. So trying the same treated CD in a modern DVD based player is going to give very different results than the same CD in an older CD only player. Because of the different tracking mechanism for DVD players, there are others things that make a much bigger difference than edge painting, primarily vibrations in certain frequency ranges, if you want to tweak DVD players playing CDs, THIS is the area to (pardon the pun) focus on. I don't know whether Blue-Ray players have the same issues or not, I haven't studied them in this regard. (I just got my first Blue-Ray player a couple months ago) John S. Indeed you're right about the IR with CD, John... However, I have never read anywhere that this actually worked to reduce errors.

True, the presentation is different, but I've always been much more successful picking out details with a good pair of headphones. Without the room effects to contend with, consistency of sound is also maintained when I bring my pair of headphones over to hear a friend's DAC for example.

[SlimDevices: Audiophiles] MUSINGS: High-Resolution Audio Expectations...
Alright guys... Time to just put this out there now that it has been a few years since relative widespread availability of high-resolution audio in the form of HDTracks and such. The recent Beck album is an important example of concerns around the wastefulness of these high bitrate files being sold. But IMO, likely of no audible benefit at all.

Re: [SlimDevices: Audiophiles] Audiophile Buzzwords, Fads, Crazes, Hypes and other Quantum Matters
Greening the edge of CD's was all the rage around the time I first got some $$$ to buy audio stuff.

Green supposed to absorb it. Buzz kill: These things never die, right?

Re: [SlimDevices: Audiophiles] What Would You Replace a Transporter With?
It will be a sad day when my Transporter dies :-( In late 2012 after the announcement that the Squeezebox was discontinued, I managed to buy a used Touch. This is the unit I did all the tests on last year. Well, I put the Touch away back in its box in storage yesterday since I still have my old SB3 for general streaming in my living room... I figure, when the time comes, it'll be the Touch -- DAC (maybe my TEAC UD-501).

IMO dynamic compression is not welcome at the mastering stage, it's different to reality ... but that doesn't mean it's -unpleasant- per se. A well sorted system should be informative, yes, but part of informing is the listener taking an interest - think infotainment! Also, taking modern recordings as a whole, Daft Punk's RAM isn't the harshest by any means? Yes, I do agree that dynamic compression itself doesn't necessarily lead to fatigue, but my feeling is that it is in general something that contributes to the sensation. My feeling has always been that a good system be neutral tonally and transparent enough to convey the lowest audible detail. I do believe the Nautilus system was able to do this. However, the music is what it is! Tracks like the disco-tinged Give Life Back to Music off RAM has a lot of high end energy and when mixed with those synthetically sharpened auto-tuned vocals, adds to the perception of fatigue for me in whatever system I listen to. While a DR9 isn't bad for the track (or for modern pop productions), I can't help but feel that the squashing of dynamics just adds to the treble overload. Sure, those sizzling trebles sound great in my car and cheap headphones, but on a superb system... Not so much IMO. Don't get me wrong though... I love Daft Punk. I would not necessarily change the production. Just that I find it more tolerable for longer term listening when I roll off the highs with an EQ from about 10kHz in the main system :-). And in the context of the Nautilus, I wonder if those trebles excite ringing in the aluminium tweeters... Archimago's Musings: (archimago.blogspot.com) A 'more objective' audiophile blog.

It seems to me that revealing systems do exactly that: they *reveal* how bad the mastering is. Examples: Some years ago I noticed that Coldplay's XY sounded pretty ropey on our main system, but acceptable on an iPod. And recently my wife bought Night Visions by Imagine Dragons - it sounds absolutely *horrendous* on a decent system, but when I put it on my laptop to investigate why, I noticed that it sounded much less objectionable via cheap headphones through the laptop's on-board sound. I loved the band 'They Might Be Giants' in university. One of the most horrendous uses of compression I came across was back in 2001 when they released the single to Boss Of Me (theme from Malcolm In The Middle). I was horrified by how unlistenable that was with some decent Denon headphones I had back then... Of course it was only years later that I figured what was going on.

Remember that some people think that the best speaker in history *ever* is the original Quad ESL - which came out in 1957. Regarding your comment about those thin speaker cables - 16AWG is perfectly adequate for audio signals. Audiophile fashions come and go. While today's dogma is for massive think cables, I can recall back in the 1980s when there was a faction who reckoned that speakers should be connected with very thin single-core cables. (And I'm sure we all remember that crazy period when Litz wire was de rigueur for hooking up speakers). Hmmm, I'll have to look for one of those Quad ESL's to have a listen :-). That's exactly why I took a picture of the speaker cable connection. Extreme bigger is better cables are unnecessary other than the bling factor. I noticed folks poking around afterwards surprised by how thin those cables looked; I'm sure thinking if bigger gauge may have improved the sound!

However, I really don't know how reasonable it would be to extrapolate those monotonic cascade of harmonics with these DACs which as you indicate are down in the -100dB and below range! Tube amps have 2nd order harmonics at something like -40dB which is orders of magnitude louder in comparison... Furthermore, those graphs in Stereophile are with input impedances of 600-ohms off the DAC. This is of course way lower than the typical preamp in the tens of k-ohms. I'd love to see DBTs demonstrating ability for people to differentiate decent DACs when volume controlled.

As I said in the article, the system can detect the slightest differences like the minimal phase filtering effects (eg. TEAC DAC filter settings)... I personally cannot hear significant differences between say the default settings of SoX filtering options for minimal vs. linear phase upsampling. I believe the system is significantly more sensitive to change in signal than my threshold for hearing (male, 42 years old, little very loud concerts in life, office job). Since people have different hearing acuity, I cannot of course prove it does or does not sound different to any specific person; as much as I cannot *prove* whether the guy I ran into yesterday was actually abducted by aliens as he claimed... What I can say is that within the limits of the system, there's not electrical change from the DAC and that lack of difference correlates to my (and my friend's) experience in listening to these cables (and with other tests I have done over the year).

As you see, there's a peak at 60Hz correlated to the AC mains hum (maybe also things like the Touch's screen refresh rate). That's down at -115dB. When the program reports dynamic range it will base the limits of the hardware off that even though for some (most) frequencies the noise floor is lower... That's why I also post the graphs rather than just the numbers so we can look at which parts of the spectrum is affected.

I guess it's best to say that so long as there's adequate shielding from noise in a non-galvanically isolated digital interface and bit perfection is achieved, there should be no differences... As a reminder, even though the cheap RCA cable demonstrated higher noise floor, the difference was really small and can be bettered with just a decent inexpensive generic coaxial cable!

My thinking is this reading is the best the EMU can perform at, no? If so, how can it show my Touch testings @ -130db as it does? Is it a guess work on the EMUs part? Should I only be satisfied with tests on gears no better than -112db? Yes, that -112dB is essentially the limits of the EMU. Remember though that this is through the whole 20-20kHz range and that the device is better (probably about -120dB) from 100Hz-10kHz which covers the frequencies our ears are most sensitive to as per Fletcher-Munson data. Should we be satisfied with -112dB noise floor? IMO... Yeah :-). I'd love to hear a piece of recorded music needing 100dB dynamic range, and none of my friends seem to listen in their home anechoic chamber! You should try running that Touch measurement again. No way it can do -130dB from 20-20kHz. If you're measuring the analogue output, you should be getting about -105dB with 24-bit audio. This correlates nicely with what John Atkinson got in the Stereophile measurements using much more expensive pro equipment.

darrenyeats wrote: Right but a reasonably intelligent and well educated person finding something -implausible- does not constitute fact! Not long ago, it was a fact that digital transports and cables couldn't make a difference for DACs, until Archimago got his measuring stick out. Just a note to clarify what the results show: 1. Yes, transports do make a difference. Small changes can be found between the Squeezebox units and laptops mainly in the extreme high frequencies... I suspect this is the result of timing differences with the -synchronous- SPDIF interface and my old adaptive isochronous USB DAC. This effect goes away with asynchronous USB DACs (ASUS Essence One, TEAC UD-501). 2. Digital cables -by themselves- do not seem to make any difference - TosLink, coaxial, USB, HDMI all measure the same for me (obviously so long as the digital data isn't being corrupted). Theoretically, extremely long cables could cause timing errors but I haven't seen this with a 12-foot length of plastic TosLink (2x6' connected with plastic optocoupler) or 25-foot poor quality coaxial SPDIF. Of course, my billionaire playboy friend Keaton Goulden-Eyre III subjectively heard differences ;-).

If not accurate to these low levels does it make wrong the results? Merci. This has been accurate in my testing. The noise floor varies depending on the frequency and usually, what I have seen is that the EMU's ADC noise floor is excellent from 100Hz to 10kHz ~-130dB with some noise susceptibility lower down and above. Less susceptible to noise as expected with the use of balanced cables and equipment. For example, no problem at all measuring the LSB of a 16-bit signal as demonstrated here: http://archimago.blogspot.ca/2013/07/measurements-dac-waveform-peeping-903db.html Easily measure below -96dB... I estimate that within the 20Hz-20kHz range, the EMU's limit is around -110dB with reasonable confidence. This is the level the Transporter and TEAC UD-501 measure using balanced interconnects. All the best with your testing Kellen! I encourage everyone with a decent ADC to give testing a try :-).

The ADC hardware seems quite capable and it's not difficult at all to get reliable results when used in testing. I'm sure there's a bit of variability as well... A quick note if you give it a try. For my unit, I notice the right channel is slightly more noisy than the left 10kHz (below -100dB so IMO still very good) so I tend to use the left channel more or average the results if possible - especially for those jitter spectral analyses.

Shutting down processes / lowering CPU utilization may reduce noise from the computer so that could be a good thing. However, it's better to find a hardware solution or shield the audio devices from the computer, fix ground loops, etc. if this is a problem!

I have yet to find a single person who I can verify as passing an ABX between 320kbps and lossless WAV/FLAC when the music is encoded with a good encoder like a newer version of LAME (I've tested about 10 audiophiles using combination of headphones or speakers)... Looking at the audiophile sites, one gets the impression as if this is some common feat! When I did the online MP3 test on my blog earlier this year, I know that some very outspoken members of other forums got the result wrong so I know for a -fact -that they're unjustifiably confident and just plain -wrong -about their self assessment. Of course this is not to say nobody can tell a difference, just that I think it's extremely -rare-. Knowing this fact for oneself is a sign of honesty and integrity IMO. I agree, no need to chase after overkill. As I've expressed in the past, I'm happy to have 24/96 as the limit of what I would bother to download (even if I buy 24/192, it's almost always converted down to 24/96). At 24/96, there's really ZERO possible audio information missing for human ears assuming one is even concerned about brickwall issues with 44kHz sampling. As for DSD, I see it as an interesting toy. I've written about it including PCM -- DSD128 upsampling and I find it sounds different, but the effect is like any DSP that can add some euphonia / body to the sound IMO. Still can't get myself to honestly believe there's anything special with DSD that cannot be captured with good PCM. I'm still unhappy about the DSD file format - useless old DSF DFF - poor tagging and compression capabilities; what a waste of storage.

In fact, it was better than coaxial and about equivalent to TosLink using the little CM6631A device for USB-to-SPDIF conversion. This is a bit of a surprise since the asynchronous USB CM6631A is usually quite adequate and relatively low in jitter as in previous measurements. Of course the jitter spectrum isn't as good as with the Transporter or TEAC stereo DAC, but it's quite reasonable and miles better than something like the distortion one sees with NOS DACs when doing the J-Test. Not to mention tube gear which would likely just drown out the signal with noise. I wrote a bit on HDMI and jitter in that post as well...

As you know the new audiophile standard for listening to computer based audio is the Mac Mini - USB - tube based asynchronous USB DAC - tube pre-amp - tube power amp, at least according to the golden eared gods at both TAS and Stereophile. Now the Mac Mini does have a HDMI port so clearly the the Quantum HDMI Squeezer + ULTRA Cable set up would be ideal except that so few audiophile DAC's presently have HDMI inputs. So my two fold question is a) what DAC's presently feature HDMI input and b) are there any plans to bring the groundbreaking technology of the Quantum HDMI Squeezer + ULTRA Cable to a USB cable?? Please, please, pretty please!! Thank you Ralph for your inquiry. 1. The gods are correct. TAS and Stereophile are written by gentlemen of distinction who are genetically devoid of earwax and hearing loss. I of course run a custom HDMI DAC because I'm worth it and could afford to hire one of the chief digital consultants at Integra, Meridian and Esoteric to design the circuitry and Nodko-san to have his boutique Japanese workshop to realize the device with point-to-point soldering using fine silver wire and hand selected/individually heard components. The gods are aware that HDMI is best, just that we in the upper crust will not release this Truth yet. In a couple years, when asynchronous USB becomes -pass�-, TAS and Stereophile will surely speak more about HDMI when the general populace is ready. Consider my article a peek of what is to come. For now, everyone else will need to use their low-end HDMI receivers or something pedestrian like the NAD M51: http://www.stereophile.com/content/nad-m51-direct-digital-da-converter 2. As in my interview, those quantum resonances are unique to small connectors and especially micro-HDMI. In recent E-mail exchanges with QuantaVibes, I do believe they will be -trying -to recalculate the equations for micro-USB! It looks like USB users could very well be in for some fun ;).

Apparently something cutting edge he's supposedly working on... Should be good. I'll post a notice here when the blog post goes up.

[SlimDevices: Audiophiles] MEASUREMENTS: PCM-to-DSD Realtime Upsampling/Conversion Effects...
Hey guys, Been away for awhile on vacation and general summer merriment :cool: Anyhow, life's busy but found some time to have a look/listen to the realtime PCM-to-DSD conversion process found in JRiver MC19. As usual, details on my blog... 'PCM-to-DSD Upsampling Effects (JRiver MC19 Beta) ' (http://archimago.blogspot.ca/2013/09/measurements-pcm-to-dsd-upsampling.html) Cheers!

Re: [SlimDevices: Audiophiles] MEASUREMENTS: Some Squeezebox numbers to consider...
Haven't been through the forums much... Lots to do over the summer to worry about audio! However, I managed to borrow one of these units from my brother-in-law to check out. So... For those who may have wondered what a current low end digital streamer measures like in terms of analogue out and as TosLink transport, this one's for you: http://archimago.blogspot.ca/2013/08/measurements-wd-tv-live-look-at-and.html Archimago's Musings: (archimago.blogspot.com) A 'more objective' audiophile blog.

Hello guys... Been away for a little while. In any case, managed to put something up from some measurements I did a few weeks back. Thought I'd try out one of Stereophile's digital tests which they've been doing for ages! http://archimago.blogspot.com/2013/07/measurements-dac-waveform-peeping-903db.html Still on vacation ;-) Hope everyone having a good July!
