I'm not sure about 0.02 Volts RMS into mine.. I had about 0.5 volts peek-to-peek. But if you don't get much mid-range at low levels it sounds like some non-linearity in the mid-driver's suspension. A hysteris-effect. My Yams keep amazingly consistent sound when lowering listening levels. Yeah, we are not getting much further with guesswork. My point was just that something 60-70 dB below maximum listening level may well spoil low level listening. (I'm listening right at the cut-off limit of the SB3's built in volume control, which I believe is 50dB below the max level. In addition I dialed in another 5 dB attenuation in the "preamp level".) Thanks for the discussion. -- 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
