OK, interesting. Re: the A500, I don't have access to the other review, but from the audiocritic data there's no reason to think this is crossover distortion - it doesn't scale the way you say it should - and it's linear over nearly two orders of magnitude in power, so the best prediction is it remains so. Even if your crossover behavior - no scaling with power - takes over right at .1W, you'd still need to go down to about .005W to equal the tube amp distortion, which is still a factor of 5 down from your listening level. Anyway I don't think we're going to convince each other at this point :-) - but thanks for the interesting discussion. FYI my speakers at barely audible level are around .02 VRMS, so you're right, that is very low. Actually they don't sound very good at that level either - no midrange. Not sure if that's due to nonlinearities in the speakers, amp, room, Inguz RC, or my ears though. You have to remember there's a psychoacoustic scaling with level - the same signal reduced in amplitude sounds different, not just quieter, because our sound percetion isn't linear. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 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
