IMHO the problem is nothing to do with the OP's hardware. This is obviously the case since he has no problems except with M4a files.
Also this is nothing to do with the SB volume/gain controls - you don't get "hiss" by reducing the bit depth - you get a grungy sound at very very low volumes. I would check that these files are not encoded with SoundCheck (Apple replaygain). Also check that replaygain is turned off in SC (settings - players - audio. An example file would be helpful...how did you rip/encode these m4a files? -- Phil Leigh You want to see the signal path BEFORE it gets onto a CD/vinyl...it ain't what you'd call minimal...SB3+Stontronics PSU - Altmann JISCO/UPCI - TACT RCS 2.2X with Good Vibrations S/W - MF X-DAC V3/X-PSU/X-10 buffer (Audiocomm full mods)- Linn 5103 - Linn Aktiv 5.1 system (6x LK140's, ESPEK/TRIKAN/KATAN/SEIZMIK 10.5), Townsend Supertweeters, Kimber & Chord cables ------------------------------------------------------------------------ Phil Leigh's Profile: http://forums.slimdevices.com/member.php?userid=85 View this thread: http://forums.slimdevices.com/showthread.php?t=48877 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/discuss
