As usual, a deflection. The question was for reliable reports of cases where asych made an improvement. Furthermore most of those kinds of problems happen on PCs with other discernable and correctible software and hardware problems. Making them go away without hardware upgrades or asynch DACs is a common topic of discussion which often leads to success. > > If you want to deny this reality then it will not surprise me.

I think there is actually one Blog article that admits that there are some problems it can't help, but even then it quibbles. > > > If any of you care to look (but beware, it takes a bit of understanding) > there is an empirical analysis of this issue by Jim LeSurf (a lecturer > in Physics & electronics) of the beloved Benchmark DACMagic Vs a > DACMagic with a Halide Bridge in front of it. See if you agree with his > conclusions & if not, why not. > http://www.audiomisc.co.uk/Linux/Sound3/TimeForChange.html I agree with his numerical results and then see that most of his charts are labelled in parts per Billion, not dB. Quick conversion chart Thousand: = -60 dB, Million: = -120 dB Billion = -180 db. I know this guy from way back and he is very careful about his claims for audibility. He seems to make none in this article. Yet another case like yesterday (the upsampled ABX) where jkeny brings in evidence that actually hurts his general position because he does not understand the data. Methinks understanding measurements would be a big help to him. That would be a life change, no? ;-) ------------------------------------------------------------------------ arnyk's Profile: http://forums.slimdevices.com/member.php?userid=64365 View this thread: http://forums.slimdevices.com/showthread.php?t=103684 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
