Eh.. I'm sure you are about to tell me? Anyway, the distortion figures will be a combination of crossover distortion (dominant for very small signals) and other non-linearities. The curve doesn't represent a single distortion mechanism. -- 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 [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
