I think it's a matter of semantics. Even with the piston example that you have, you can say the speaker piston is in effect a DAC, in a broad sense, since it converts digital signals to analog sounds via pistons. In a traditional DAC sense, you won't see any literature on Digital amps say that they have a DAC in their amps. -- khewa ------------------------------------------------------------------------ khewa's Profile: http://forums.slimdevices.com/member.php?userid=4751 View this thread: http://forums.slimdevices.com/showthread.php?t=22502 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
