I've replaces the rca's between the 950 and amps already, When I fire the system up with no source selected, there is no hiss. I have no gain controls on my amps, I've already calibrated with the spl meter and all my trims are set at 0. Another thing I noticed last night when my wife turned on the vcr the hiss tripled!! Really loud! Troubleshootings a real pain because the systems in a huge oak wall unit!
