No, there aren't any perfect DAC's. Let's see, I said: Now, if there's some DAC that doesn't do a good job of digital to analog conversion, yeah, y'all might see that kind of thing, in which case, fix the blamed convertor, eh?There are, however, DAC's that rebuffer data, and that amount of memory is inconsequential in terms of cost and complexity. The whole idea of the timing of the digital data affecting anything is a complete red herring, and one that needs to die a very quick and final death, unless the device is getting the DAC clock from the data, which is not the case in point here. (If it is, there's a lot more wrong than mere DAC design, let me tell ya.)
Therefore, the questions of:
"The pattern of digital data transitions would be entirely different, so any data related jitter patterns would be different. The lossless coding might have a less 'busy' data stream, but be busier internally due to the decoding. "
can be trivially and completely eliminated. Certainly grounding and elementary analog design constraints remain. I would hope (against hope, it seems) that such is not a problem in the modern world.
Given, of course, design methods that y'all can find in the old TI TTl handbook, of course, your hypothesis is dismissed completely.
Now, y'all can continue to tilt at windmills, or y'all can just get down to hardware design and find out what is (*&&(*ed up, if you hear any difference at all, well, that you can actually reproduce accurately in an unbiased setting, that is.
Finally, it's just plumb rude of you to even suggest that I
"pretend that all audio equipment does it's (sic) job perfectly",
you know. In the article I replied to, I said:
"Now, if there's some DAC that doesn't do a good job of digital to analog conversion, yeah, y'all might see that kind of thing, in which case, fix the blamed convertor, eh?"Which is just opposite of the fib you all tried to put in my mouth.
