Well, this thread seems to have moved on a bit (towards the same old tedious argument that 99% of threads in this forum eventually arrive at), but seeing as you asked....
*IF* you want to obsess about making sure jitter is minimised, then yes, I agree that in the context of your DAC, an asynchronous USB feed is the correct solution, as it's the only way you can ensure that the DAC's own clock is used as the master. However, the only properly-controlled studies into the effects of jitter on audio playback I have ever seen (Benjamin & Gannon, 1998; and Ashihara et al, 2005) came to the conclusion that really quite high levels of jitter (20nS+) makes no audible difference to normal music programme material. So striving to achieve the lowest possible jitter might be a wild goose chase. You say you've heard better and want to try and get there. But when you heard that, was the system and the listening room the same? Were you in the same frame of mind? What was the weather like? All of these things will affect what you hear far more than the transport and DAC. I have an anecdote that I like to trot out at times like these. Once in my life - just once - I heard a solid, 3D, holographic image of a jazz band in my living room. The kind you can walk up to and put your hand on the trombine player's shoulder. It was when playing a vinyl LP through a pair of speakers well known for their lack of imaging capability (Linn Isobariks). I played the same LP the next day and the effect was gone. I've never heard it again. What you hear is far more to do with what your brain gets up to than the actual soundfield produced by the stereo system. ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=95031 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
