Just to clarify, static is usually characterized by some slightly random popping or crackling. It could indicate noise getting into the signal from bad cables, loose connections, noisy equipment nearby radiating, maybe even bad power. When radio was more popular, static was often heard in the background of distant stations. Hiss on the other hand is a more constant white noise type sound that is usually generated in the preamp or amp stages in a system (and less likely to be caused by cables or connections). Which of these descriptions sounds more like what you're hearing?
Edit: I'll just add that if your answer is 'Hiss', the place to start would be to turn everything off and disconnect the inputs to the XPA-3, then turn it back on. If you still hear the hiss then your speakers may be sensitive enough to reproduce the low noise floor of the amp. It's also possible that something's wrong with the amp, but if all three channels are the same that's not likely. If the noise goes away then something upstream (like the Denon) is creating the noise.

I tried disconnected the inputs to the Xpa-3 and im still hearing the hiss so i guess its just something im gonna have to live with? |
