Deleted? I don't think so... did you find a broken link to a discussion or something? You will find many threads here on the subject. In particular, look for discussions about digital volume control where we've talked about SNR and how to set the volume levels at the source and the preamp. To answer your question no, changing the external PSU will not materially affect the noise floor. -- seanadams ------------------------------------------------------------------------ seanadams's Profile: http://forums.slimdevices.com/member.php?userid=3 View this thread: http://forums.slimdevices.com/showthread.php?t=28397 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
