RE: Not true for async systems

Posted by AstroD on January 6, 2011 at 13:26:23:
We have to define jitter as both a timing issue and a signal quality issue. Based on my experience with AC quality affecting the sound quality, digital signal quality is very important. I haven't tried other high end DACs, but how clean the signal is has to affect the performance of most DACs, since it is an analog electrical signal. This is where digital becomes as tweakable as a vinyl rig...

I just got Ubuntu Studio 9 running last night (10 would hang on install). When the rt kernel would hang playing video, I did a brief test comparing the real time kernel with the stock "low latency" kernel and the stock kernel actually sounded a bit better, but it was very close. It sounds better than my Win7 and Mac systems ever did.

I think Macs already have the timing/prat (macro jitter) issue nailed, but in my experience, the ability to undervolt is key to getting max SQ, and that's where Linux gets you great timing and the ability to undervolt and underclock. Anyone here have a Hackintosh?
