Got an Onkyo HT-R591 receiver yesterday as part of the HT-s5500 HTiB. Seemed pretty quiet when I first powered it up. I even wondered if it was on. Sounded OK.
This morning I ran Audyssey 2EQ set up with the mic and all of the sudden ... Noise. When there is no source coming in the system is quite noisy at about 50%. Start turning off Audyssey engaged features (Audyssey, Dynamic EQ, Dynamic volume) and this helps a little, but still have noise.
So does Audyssey introduce that much noise thru the set up changes it makes or is this just a product of a budget amp that i did not notice at first? I am thinking of hitting the Factory Reset. I really did not like what Audyssey did to the settings and setup I had already made.
