Good power amps either block DC at the input using a capacitor, or have a DC servo (better) that removes any DC component of the signal. Assuming that speakers are as good as you assume seems like one assumption too far. The whole point was that it was a possible explanation to hearing polarity reversal. And it was a good point too -not to be dismissed. -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=22118 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
