most decently-built solidstate amps usually has no hiss at listening volume. some better ones even when volume maxxed out exhibit no hiss.
whatever the case hum should never be present at all in any volume. there are many causes of hum, from the imperfectly-filtered power supply unit leaking into the amplification stage (nothing much u can do about it, since it is inherent) another source of hum is the improper connections of the RCA, due to oxidation of the terminals or loose connections, creating ground loops. determine where the hum is coming from by disconnecting all the RCA inputs & using shorting RCA plugs. if it is absent, there is a good chance that the problem does not lie with the amp. -- musicexpression ------------------------------------------------------------------------ musicexpression's Profile: http://forums.slimdevices.com/member.php?userid=28861 View this thread: http://forums.slimdevices.com/showthread.php?t=62723 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
