The fact that they don't stop dead but roll off was an implicit part of my point, the ultrasonics are there, even if they are increasingly down, and we don't yet fully understand their effects - I think that we are in serious agreement here!

I think that it was a good (and at the time the only available) product engineering choice but I don't think that it was a good sound/music engineering choice ... :-O Mike -- reeve_mike ------------------------------------------------------------------------ reeve_mike's Profile: http://forums.slimdevices.com/member.php?userid=995 View this thread: http://forums.slimdevices.com/showthread.php?t=26685 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
