Re: [SlimDevices: Audiophiles] MEASUREMENTS: Do Bit-perfect Digital S/PDIF Transports Sound The Same?
Nice try. Wrong subject. Nobody is discussing Aeris DAcs. We're or better I'm discussing your problems and your partially limited view of looking at things. You don't want me to dig out more examples!?! I'd like to add some more stuff to this thread. The OPs attempt of measureing digital software players such as JRMC JPLAY FOOBAR etc. lead to no results or better neglectable differences. You'll find some lengthy blogs about it on his blog page. Why do I bring this up over here. I do see a kind of relation. The OP doesn't understand that his high quality Teac DAC ( I do also have one at hand) tries everything to manipulate the incoming data. Exactly that what a measurements chain shouldn't do. There's a lot of signal recovering, refreshing, reclocking and filtering involved in a DAC device. That signal refreshing is pretty much similar to above WM8805 example. The better it's done the less problems remain on the output. The Teac DAC probaly does an even better job then the the WM8805. The OPs SW player measurements just show that his Teac+EMU (digital-analog-digital-analog ??) maesurments chain is doing such a good job that his EMU is not able to show significant differences. It doesn't say anything about the SW player performance and a potenially relevant USB layer 1 impact. Relevant measurements would have to be conducted on the physical USB interface. Otherwise no reliable results can be expected.

I assume therefore you are the one mistaken. Toslink can exhibit several 100ns of jitter - do you mean ps?

BTW: What's with the To me this (your) exercise is useless and misleading comment? Such an offensive tone is barely constructive in this or really any domain don't you think? Suppose you were correct in your comments above... Don't you think it's still useful to document the (slight) differences between transport devices and encourage others to explore the question since results could vary depending on the SPDIF receivers? Just take a Cirrus CS8416 or a TI DIR 9006 instead of WM8805. They all have similar specs -- on the intrinsic jitter part. The CS8416 is the worst here. The Wolfsons WM8805/4 seem to attenuate jitter best. I'd guess that you'll find one of those three in 95% of all the devices out there. No. I mean Nano Seconds. Have a look at the datasheets or e.g. Phillips TORX Toslink transmitters. Just ONE side exhibits theoretically up to 15ns ( n as in nano) jitter. Now take the airgaps, the 2nd side, the cable asf asf. It's the WM8805 ( or something else ), which gets that SPDIF jitter down. We should not mixup SPDIF jitter specs and I2S jitter specs. On I2S we need pico second jitter. On SPDIF you can have 100ns and the receiver will still lock to it. Besides those transceivers you'll find in quality DACs even more jitter attenuation methods ( FIFO reclockers, ASRCS asf, the Sabre does it inside). All these will mess up your measurement results by improving the digital input signal. Measurement equipment or setups are not allowed to change a signal! Otherwise you'll measure the performance of your source + your measurement equipment performance. You might want to read this 'Wolfson' (http://www.wolfsonmicro.com/documents/uploads/misc/en/Jitter_performance_of_spdif_digital_interface_transceivers.pdf) document.

Which, brings us right back to the point, having read various audiophile forums and publications for years, that the real world experience of touch users you speak of is anecdotal and typically has no control for subjective factors. So sure, these listeners do believe their perceptions, but no one has any idea if that is due to some technical performance aspect of the equipment or whether they are impressed by the appearance, reputation or some other non-audio aspect that influences their opinion. The problem with subjective influences is that what positively influences one person's perception may be a neutral or negative factor for others. Once again, I am fascinated by the consistency with which subjective audiophiles reject the possibility that their perception may have been influenced by subjective factors, refusing to make any control for it whatsoever.

Well, the Touch as transport does perform pretty darn well in comparison to the direct USB input considering the limitations of an SPDIF interface! Sounds very good to me as well in stock form, so why should I disagree? I'm going to fundamentally disagree though that real world experience of hundreds of touch users is: A. A fact... Where's the survey? Who was asked - apparently they missed me and maybe Mynb? Did they ask the average music lover or only card-carrying audiophiles? B. Substantiated... What's inadequate about the Touch as transport? How was the conclusion arrived at by the hundreds? That comment is truly what is misleading - in itself presented as fact when it appears at best as opinion if not just some kind of vague impression. It's like saying that there are hundreds of members in the Flat Earth Society (who knows... there probably are...). Am I supposed to be impressed?
