I know that 120VA is overkill, but look at Naim Audio and their power supplies for preamps. Why they are doing it ? Are they so stupid ? Big transformator has lower impedance, than the small one. Good power suplly should have the lowest possible impedance. Thats the reason why i took one 120VA :) -- praganj ------------------------------------------------------------------------ praganj's Profile: http://forums.slimdevices.com/member.php?userid=41091 View this thread: http://forums.slimdevices.com/showthread.php?t=82648 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
