Using an oversized transformer for the demands of the circuit is not just a waste of money but also BAD for your circuit. The larger the transformer the MORE emf it generates which is one of the big noise generators in audio. Also an oversized transformer will produce higher voltage than needed for the circuit and cause your voltage regulators to work harder and produce more heat. Unless you are connecting your amps directly to the transformers secondaries they they will NEVER see the "lower impedance" of the transformer. That should be handle by the PSU not the transformer. -- m1abrams ------------------------------------------------------------------------ m1abrams's Profile: http://forums.slimdevices.com/member.php?userid=850 View this thread: http://forums.slimdevices.com/showthread.php?t=82648
