Hiss noise from speakers


I have a Rotel RC-1070 pre, RB-1070 amp, RCC-1055 changer & B&W804N spealers with an ASW800 sub. I can hear an audible hiss in the B&W tweets but when pre is turned off hiss is gone. Any ideas or solutions? IC are Straightwire Concertos. Thanks.

All electronics have some noise. If you have to put your ear to the tweeter that is normal with the volume turned up or a tube piece.
