Well, I can't find out much about the O/Ps Tact 2.1. But the Tact 2.2 claims to have "immeasurable" distortion and noise when used with digital inputs and outputs. They also claim that their sample rate converters give "extreme jitter attenuation" and the input signal is resampled (and therefore presumably reclocked) to 192khz. So, my original point stands. If the Tact (for example) can't treat two digitally identical inputs the same, then it is either useless or broken.
I am not suggesting that in the O/Ps case, the Tact is causing the differences he hears - I did in fact suggest he try listening to both sources with out it - I am trying to raise the possibility that if you buy Stereophiles claims that a hard disc drive sounds better driving a given DAC it follows that the DAC isn't really very good or it is defective. I would make the same argument about (say) speaker cables. If an amplifier and speakers sound different when connected by two different speaker cables, then either the amp is useless or broken, or the speakers are. If your amp can't get a signal down a piece of wire what chance has it got getting it through the vastly more complex load that a speaker presents?! Instead of spending a fortune on different speaker cables, and issues of Stereophile, buy a decent amp that is untroubled by a few feet of wire. -- JezA ------------------------------------------------------------------------ JezA's Profile: http://forums.slimdevices.com/member.php?userid=21219 View this thread: http://forums.slimdevices.com/showthread.php?t=57173 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
