+1 That guy is clearly wrong he do not understand Nyquist :) in fact all the reasoning you cited (cant find that post ) is clearly the usual spiel from someone who actually don't understand the sample theorem and is influnced by audiophile beliefs . They usually miss that the signal is reconstructed by the fillter and that it is bandwidth limited ,they usually don't get that sampling can catch everything about a signal 1/2 the Nyquist frequency including the temporal information yes the time domain is intact there is no loss of timing accuracy. The usual audiophile myths is that time resolving is limited to 1/44.1 for CD this is not true ,just look at the reconstructed analogue signal it looks continues to me and will be identical to to the original -bandwidth limited- signal . So yet again you can only benfit from higher fs in the source material if can hear above 22.05 kHZ (if no gremlins are involved ) and a bandwith limit is functionally the same regardless if it is done digitally or by analogue means . Don't confuse with practical solutions there are all kinds of good reason to have dacs and adc oversampling to very high rates and dito to actually record stuff in 24/192 in the studio but consumer playback is another thing . ------------------------------------------------------------------------ Mnyb's Profile: http://forums.slimdevices.com/member.php?userid=4143 View this thread: http://forums.slimdevices.com/showthread.php?t=69882 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
