Cool, I thought had noticed this difference between my AVR630 a higher end Sony, and the DPR1001 but wasnt sure if its because the recording was bad. This is not something I am too familiar with (if amp signal to noise is causing hiss or if its the recording). I am certainly interested in keeping this to a minimum as there is audible hiss at my preferred listening level of around -10 to-5 from reference level. The 7125 should therefore theoreticaly lower this over the AVR amps.
