I've been given to understand that the Squeezebox duet measured with an output impedance of 593Ohms worst case and my amp input is at 32KOhms. I think I can use a nice Goldpoint 50K. -- sxr71 ------------------------------------------------------------------------ sxr71's Profile: http://forums.slimdevices.com/member.php?userid=18773 View this thread: http://forums.slimdevices.com/showthread.php?t=55246 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
