You may need an upgraded linear power supply but you definitely do need an external dac to improve the sound. I tried my older SB3 analog out versus into Benchmark Dac 1 a few years ago and the SB3 needed to go into the dac to improve the sound. Linear supply is another matter - the differences with a cheaper power supply are not that great in my experience. -- mr_bill ------------------------------------------------------------------------ mr_bill's Profile: http://forums.slimdevices.com/member.php?userid=6737 View this thread: http://forums.slimdevices.com/showthread.php?t=49041 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
