[SlimDevices: Audiophiles] LP-Digital Conversion?
So, what's the state of the art today? I'm sure there are some folks here who rip LP's. I'm thinking about dipping my toe in the water, since some of my music interests seem to be increasingly only on LP. I'd prefer to do 24/96. What turntables are good? Are any of the USB turntables decent? I have an iMac. Anyone here have suggestions for that, too? What software do you use? Basically, I am soliciting pretty much any feedback, as I really don't have much of a clue. As some of you may know, I have been primarily a digital-analog guy, not the reverse. -- ezkcdude There are 10 kind of people in the world - those who understand binary and those who don't.

So, the new headless receiver takes an 9V DC supply and has internal linear regulators (makes sense given the 6Vpp analog output + overhead needed for the regs).

Re: [SlimDevices: Audiophiles] Square waves are not very helpful for audio
Sean, I get everything your saying. Obviously, I don't think people should base their decisions on this one type of test...still, it's interesting, at least. And JA doesn't really give rationale for doing these tests - maybe just because he can? However, if you look at the higher end amps they review, and compare with the relatively lo-fi ones, the square waves are typically produced better by the former. This correlation doesn't prove anything, but it does suggest to me, anyway, that the tests could be meaningful. (And he does also do FFTs and all that good stuff.) Maybe I should ask JA himself about these square wave tests over at the Stereophile forum. -- ezkcdude There are 10 kind of people in the world - those who understand binary and those who don't.

Re: [SlimDevices: Audiophiles] Bits vs. Hertz - Bit depth or sampling rate more important for audio?
Thanks, for the responses. You pretty much confirmed what I had been thinking. So far, I'm quite happy with the H2. The (membrane) buttons are a little chintzy, so I hope they hold up. For voice (podcast) recording, I couldn't imagine needing any better. I recorded some thunder the other night, and my girlfriend in the other room was rather surprised when I started playing it back (through my SB3, of course). She actually had to ask me whether it was real or my recording. The next two chances I have for real concert recording are The New Pornographers and Of Montreal in November. I think I'll go with 24/48. BTW, I did a short recording today in 24/44.1 (WAV), and converted the WAV-FLAC. I was able to play back both files through the SB3, and I noticed that SlimServer (if it's still called that) lets me know that the WAV is 24-bit. However, the FLAC info doesn't seem to contain this, so I'm wondering whether it is 24-bit or maybe got truncated to 16-bit. Does anyone know of a program provides this info?

Re: [SlimDevices: Audiophiles] Squeezbox with Word Clock in, AES/EBU etc.?
I think what acoustic wants, and he can correct me, is a Transporter with out the er. IOW, a Transporter minus the output stage. I would also be interested in such a component, perhaps, with only a single display. If that came in around $1000, I'm sure there would be plenty of folks who would want one. I don't know if there would be enough demand for it to make sense financially for SD/Logitech, but all the same, I'm with acoustic on this one.

opaqueice;230035 Wrote: Interesting - thanks for the detailed summary. Have you heard differences with modern jitter-rejecting DACs? The Benchmark DAC1 for example? According to their measurements it's totally immune to input jitter, so if you hear a difference it would have to be for some other reason. To be fair, this is what is written on the Benchmark website: The Benchmark UltraLock#8482; system is nearly 100% jitter immune. The D/A conversion clock is totally isolated from the input digital audio clock in a topology that outperforms two-stage PLL designs. In fact, no jitter-induced artifacts can be detected using an Audio Precision System 2 Cascade test set. Measurement limits include detection of artifacts as low as -140 dBFS, application of jitter amplitudes as high as 12.75 unit intervals (UI) and application of jitter over a frequency range of 2 Hz to 200 kHz. Any signal that can be decoded by the USB or AES/EBU receivers will be reproduced without the addition of any measurable jitter artifacts. The AES/EBU receiver IC has been selected for its ability to accurately recover data in the presence of very high jitter levels. Note it says nearly immune. And in the last paragraph, will be reproduced without the *addition of any measurable jitter artifacts*. That is pretty clever ad writing. It does not say totally immune to jitter or 100% jitter rejection. With the ASRC they are using, that would be impossible. Sure, jitter can be reduced a lot, and while I personally doubt that jitter at these low levels is audible, it is wrong to say there is *no jitter*. -- ezkcdude There are 10 kind of people in the world - those who understand binary and those who don't.

[SlimDevices: Audiophiles] Are you a videophile, too?
Having visited AVS forums on several occasions, but never lingering for too long (knowing that would cause me never to buy another tv again), I noticed videophiles tend to be very different from audiophiles. Videophiles seem to obsess about measurements, while audiophiles seem to shun them. I hypothesize that this is simply due to the fact that video is easier to measure and calibrate - heck I can calibrate my tv with a $30 DVD any time I want. Audio is much more difficult. With video, you can readily see issues that come up - pixelization, rainbows, banding, digital artifacts, staircase, the list goes on. At the same time, even though many of us can obviously see the differences between monitors (with our own eyes) - I would argue much more obvious differences than we can hear with our audio systems - paying thousands extra for slightly sharper picture, albeit noticeably sharper, isn't usually worth it. I guess it's because with video you can really know what you're getting with that money. With audio and audiophiles, everything seems so much more subtle and unknown (and unmeasurable). How many threads have we had about jitter - debating whether it's even audible? I sometimes wonder if audio measurements and observations were as obvious as with video, would there be as many audiophiles? Who knows? Maybe there would be more because people could point to actual differences (and pay for them, too). For myself, I think I would probably have the opposite reaction. If I can judge the differences clearly - like I do with video - then I know what I'm willing to pay for. Would I pay $3000 for a Sony LCD, when the $1000 LCD at Costco is pretty much the same - heck no. How many audiophiles routinely *do* pay thousands more for components that seem pretty much the same to most people? Would they *still* pay thousands more if there were rigorous standard measurements that told them the more expensive component was only marginally better? At least with video, one typically knows what one is paying for. -- ezkcdude There are 10 kind of people in the world - those who understand binary and those who don't.

However, I think the professional market is quite large, and it would make sense to me to target them with a product as useful as the Squeezebox, but with professional features (eg AES/EBU, wordclock). In fact, it may not even be as much about the sound, but simply that most professional gear already has these connections - and much of it doesn't even have consumer SPDIF (RCA), for example, try finding coaxial SPDIF output on professional souncards. So, if *I* were making a professional version of the Squezebox, of course, I would add AES, word clock, etc. Otherwise, no pro would even think about buying it for *professional* use. Even if true, that still wouldn't answer what I was interested in knowing: whether the additional appeal it may or may not have to audiophiles who -can/could- use its AES/EBU and WC options is justified. I'm sure you realise by now I wasn't interested in theoretical considerations as to why it may or may not be, but first hand experience. I think it would be overkill for most consumer applications. Maybe if you had 10m or more of cable, it would make a difference. And maybe there is a small segment of the audiophile market that is really clamoring for these professional features.

Re: [SlimDevices: Audiophiles] Squeezbox with Word Clock in, AES/EBU etc.?
So, I went to the Stereophile archives to look for JA's DAC measurements. I found some very interesting things. First, both the Squeezebox and Transporter perform very well compared to even the best gear, in terms of p-p jitter. The Squeezebox is around 300 ps, while the Transporter is around 200 or so. Interestingly, the dCS Verona Master Clock clocks in with a jitter measurement slightly higher than the Squeezebox. Also, JA found that with the Nagra DAC (supposedly a modern DAC that rejects jitter): Driving the Nagra DAC with S/PDIF data from a PS Audio Lambda CD transport gave a measured jitter level of just 140 picoseconds peak-peak, which is superbly low. with almost all of that jitter data-related (red numeric markers). Changing the data source to my PC playing a WAV file and connected via a TosLink cable increased the jitter level to 333ps, with the increase due to low-frequency sidebands (not shown). While this is still very low in absolute terms, the difference between its electrical and optical performance suggests that the Nagra is not totally immune to data interface issues. Compare that with a claim from the Nagra website (my bold): The DAC features an ATF (Adaptive Time Filtering) module that increases the quality of all signals just before the conversion stage by *eliminating the jitter*. I didn't read whether JA heard any difference between the two interfaces, but it does show that simply the difference b/w two interfaces (well a different transport, too) on even a very high-end DAC can produce very different levels of jitter. It also makes one question the marketing claims. -- ezkcdude There are 10 kind of people in the world - those who understand binary and those who don't.

You said you heard differences when you did blind testing - but not with SB3 or Transporter. Ok, I can believe that. No problem. Difference between SPDIF and AES/EBU? I can think of at least one reason there could theoretically be a difference: noise. AES/EBU should be transformer coupled (either on the output of the transport or input of the DAC). The galvanic isolation could provide a reduction in noise - which could affect things, at least, in theory. These differences could be even greater if the cable length is very long (10 meters, let's say). So, while I don't believe jitter is a major concern with the SB3 or Transporter - I could imagine that noise is a concern that could be audible. BTW, my ezDAC (a DIY DAC I have designed) is transformer-coupled on the input, so you know I'm not just saying this for no reason. One last question - which may help all of us. Do you have any recollections from your testing of what qualities could be detected between these formats/transports? For example, was it as obvious as more/less noise? Or was it more subtle, like stereo imaging/separation/etc?

Ok, I think I understand now. I brought up jitter, because isn't jitter the only variable between different transports, if the signal is being sent to an external DAC? If you are not concerned with jitter generated by the transport, then why do you want a Squeezebox with word clock, etc? What other transport issues are there that one should care about other than jitter (assuming bits are transmitted without errors in the first place, of course)? It seems to me that only timing is the issue, and the way to quantify differences in timing is really the definition of jitter.

Re: [SlimDevices: Audiophiles] Sb4 ?
After almost two years with my SB3, I'm not convinced that an SB4 could really offer much substantial improvement. Sure, the power supply could be made linear, or the DAC stage could be upgraded, but most people who care about such things will inevitably, if not invariably, purchase an external DAC,anyway. The only feature I still would like to see is support for external plugin drives (USB, flash, etc), but that seems to be out of the question, due to architectural issues. -- ezkcdude There are 10 kind of people in the world - those who understand binary and those who don't.

The fundamental problem with CD (or vinyl or any other format over the past 100 years) is that the playback mechanism was somehow dependent on the physical format. What the SqueezeBox (or generally the PC) does that is revolutionary IMO is separate the data from the physical carrier. Thus, we no longer need to debate pit spacing or green pens for that matter.

can find a true 5V linear psu.-

That said, if your going to be stubborn about this...It depends how the
regulation is performed on the SB3. If there is onboard regulation,
which I think is the case, it may be safer to feed the higher voltage
(6V) than a lower voltage. In the case of going with lower voltage, you
run the risk of voltage dropout, which could damage the chips. The
higher voltage would be no problem in this case (except generating a
little more heat, but I wouldn't think that is a major problem.) Of
course, the best thing to do is use a 5V source, as a I said above.

No doubt, but if you don't care about subtle differences, 99% of audiophilia might as well be tossed out the window. My point in even starting this thread is really that there may be an alternative to A/B/X testing for audiophiles who don't like A/B/X testing (you know who you are already). It seems to me that hearing differences that can't be heard with A/B/X (by some listeners, anyway) is important, and would go a long way to actually validate some of the claims that the flat-earthers as you guys call them are routinely chastized for.

Re: [SlimDevices: Audiophiles] TP: Upsample any source up to 96 kHz in slimserver?
Here's a practical difference between the two terms, at least in DAC design: upsampling occurs before the DAC chip, typically with an ASRC, while oversampling occurs in the DAC chip, itself, right before the analog output stage. Of course, DAC's can have both upsampling and oversampling. I believe the Transporter does not upsample, meaning only that the frequency of the signal sent to the DAC is 44.1. OTOH, an upsampling DAC, such as my own DIY design, upsamples to 96 kHz (i.e. the input to the DAC chip is 96 kHz). The DAC then also has oversampling (which is essentially non-defeatable in PCM1794), and a soft rolloff filter. -- ezkcdude DIY projects page: http://www.ezdiyaudio.com System: SB3-EZDAC-MIT Terminator 2 interconnects-Endler Audio 24-step Attenuators (RCA-direct)-Parasound Halo A23 125W/ch amplifier-Speltz anti-cables-DIY 2-ways + Dayton Titanic 10 subwoofer He's not hi-fi, he's my stereo. ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=32940 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

I wonder if we could create a survey that would help us understand the demographics of this argument. -- ezkcdude DIY projects page: http://www.ezdiyaudio.com System: SB3-EZDAC-MIT Terminator 2 interconnects-Endler Audio 24-step Attenuators (RCA-direct)-Parasound Halo A23 125W/ch amplifier-Speltz anti-cables-DIY 2-ways + Dayton Titanic 10 subwoofer He's not hi-fi, he's my stereo. ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=32352 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

So much for that distinction. Not true, of course. Let me give two very contemporary examples. We have incomplete knowledge of climate change, yet the IPCC recently reported that it is very likely (90%) human activity is causing it, at least, to a large extent. I would say the argument that climate change is caused by man is plausible, wouldn't you? We also have incomplete knowledge of how evolution works, but, to say the very least, it is obviously plausible as a scientific theory. For you to say that we must have complete knowledge of a phenomenon before we can create a plausible operational theory is just plain stubborn, if not ignorant. -- ezkcdude DIY projects page: http://www.ezdiyaudio.com System: SB3-EZDAC-MIT Terminator 2 interconnects-Endler Audio 24-step Attenuators (RCA-direct)-Parasound Halo A23 125W/ch amplifier-Speltz anti-cables-DIY 2-ways + Dayton Titanic 10 subwoofer He's not hi-fi, he's my stereo. ezkcdude's Profile: http://forums.slimdevices.com/member.php?userid=2545 View this thread: http://forums.slimdevices.com/showthread.php?t=32352 ___ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles

My point was that the concensus can and will change, and it doesn't follow that reality has actually changed because of that. Ergo: Concensus doesn't imply truth. No, you're missing my point. Who should make the consensus? Scientists or dabblers? What we are continually being told by climate change skeptics, almost all of whom are outside the scientific community, is that there is a robust debate going on. There isn't. One only need go back to the 80's and follow what happened with AIDS. Sure, there was an initial hysteria, and some bad science. But long after the disease of AIDS had been figured out (i.e. symptoms, population, retrovirus), there were skeptics who either a) thought AIDS was created by our government, as a result of biological weapons reasearch or b) AIDS was a punishment from God for deviant behaviors. I would suggest we are in this phase with climate change. In 10 years this will look like a silly debate.
