I agree. First of all, I know nothing about what Gena was talking about...waaay over my head! However, I know what I hear. I had a cheap Sony AVR which was rated with over 3x the power of my first Denon. The sound didn't even compare. Regardless of volume, I couldn't believe the amount of hiss that was removed with the Denon. I didn't even have to put my ear up to the speakers to notice it.
