Well, there's nothing wrong with talking about quantum voltages, quantum currents, etc. - that just means the number of electrons involved is small, so quantization effects come into play. However the number of electrons flowing through an audio circuit is of the order of 10^18 (1 with 18 zeros after it). Furthermore there's no such thing as "quantum noise energy", except maybe as a strange way to refer to quantum contributions to the energy of vacuum (and please don't anyone tell me the cosmological constant matters to audiophiles!). Anyway, we're at risk of falling very far off topic... -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=26332 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
