I didn't try other frequencies - I can later. But I don't think that can be the answer, because if the signal beats against something with one polarity, it will beat against it just as much with the other polarity as well, no? I agree it's weird about the change in pitch. I guess it might be that the response of the speaker to bass is quite asymmetric, so the bass is just louder in one than the other (which could be what I heard). That fits with what you're saying, but if that's it I'm surprised it's such a big effect... -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=23759 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
