Your figures about tube amps are just plain wrong. How did you arrive at them? Also, it is the nature of the distortion that decides if it is pleasant or awful, not just the level. "A couple of watts" are in fact quite a lot. If listening at low levels you might only use 1/10 of a watt or less. In such situations any crossover distortion will suddenly be very dominant. THD should be measured at very low levels to unveil this kind of problem, but crossover distortion is so 70's that people just don't even look for it much any more (but distortion getting lower with increasing power should have triggered alarm bells). -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=31843 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
