Despite coming from an engineering background and being firmly of the opinion that it couldn't possibly matter, my opinion on the audible impact of clock jitter was changed forever when I sold my early, expensive DVD player and replaced it with a cheap recorder.
I figured that 'bits is bits', and that as long as both managed to deliver a correct SPDIF output, both would sound identical through the same external DAC. (The one in my Yamaha DSP-A1, in this case). I was wrong. It took me a couple of weeks to fully realise it, but my music sounded flat and two-dimensional. The soundstage had become fuzzy and indistinct. On a couple of occasions it was so annoying that I had to just switch it off. Yet, in a quick back-to-back test, I very much doubt I'd be able to tell the difference. I ended up having to buy a new player, and sure enough, that cleared up the problem immediately. On the technical side: typical accuracy for a quartz crystal is around +/- 50 parts per million, with higher precision available at exponentially increasing cost. So, if the source and DAC were mismatched by that amount, the DAC would have to interpolate or drop 2.2 samples per second. Audible? Probably not. Good for marketing? Unlikely. -- AndyC_772 ------------------------------------------------------------------------ AndyC_772's Profile: http://forums.slimdevices.com/member.php?userid=10472 View this thread: http://forums.slimdevices.com/showthread.php?t=33146 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
