Consider how much slower an optical drive is than an HDD, and yet, PCs do actually, although we don't often admit it (or even actually need it) play music from their CD drives, just fine.

It has nothing to do with interruptions. When you start getting into the deep end of the pool in terms of optimizing a standard PC for audio, the idea is that having HDD I/O during playback is a source of noise, so all music in RAM, less I/O, less noise. That's part of the goal behind JPlay's hibernate mode. Once enabled, all HDD I/O stops, not just the music files, but everything. You can physically disconnect the system drive, and playback will continue.
I don't care to take things that far. VortexBox is good enough for me.
Thad E Ginathom:
I think that there are two possibilities: one is, as you say, something else electrical going on is a source of noise. Some people say that. The other is to do with interrupts, where buffers do not get filled because the machine is doing something else. Hearing the mouse pointer move across the screen, as the system prioritizes video over audio is not nice, and it is noise. DPC latency, if the course is not easily traceable, is an audio nightmare, It's the reason my last PC was thrown out. On a par with a flickering fluorescent light!
Although I love to rant about Windows, my initial forays into Linux audio absolutely needed a rt kernel for un-[literally]-interrupted playback with the interfaces I was using. Then the Low-Latency kernel would do. Now I'm running a generic kernel and there is never a drop out, unless I forget to fix the CPU speed adjusting thingy.
Judeus:
just curious, any early thoughts on the wyrd vs regen anax?
ohhgourami:
Looks like this isn't happening then...
Yuanathan:
Echoing Solderdude comment above, looking at the exceptionally good measurements of GMB and Yggy from Atomicbob, it really makes me wonder how does all the jitter rejection/improvement devices work to improve these dac? Anyway all these does is to pique my interest of Anax's comparison. popcorn popcorn
Deep down of course I hope for all these to be placebo, even with money back guarantee of some of these tweaks, the return shipping to OEM from Asia to USA/Europe alone makes me :-[ :-[
