FWIW, I use my SB3 with the original SM supply, feeding an external DAC/Preamp (TacT). Adding a filtered power strip (it's the only unit on that strip) to isolate the SBs power supply from the rest of the system gave a remarkable improvement in sound quality (very unexpected, as I'm using digital transfer). Given this result I would be surprised if a linera supply didn't also affect the sound. My theory is that it is the SM-supply's connection to the mains that gets better filtering now, hence affecting the TacT less. But is is only a theory. -- P Floding ------------------------------------------------------------------------ P Floding's Profile: http://forums.slimdevices.com/member.php?userid=2932 View this thread: http://forums.slimdevices.com/showthread.php?t=20725 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
