I think I know the answer to this but wanted to double check. Other than being routed through the receiver's volume control, is the R-972's 7.1 channel analog input essentially a pass-through connection with no other processing or "molesting" done to the signal? I know that Trinnov processing is not available on that particular input, but was wondering if the unit does anything else to the signal that would have a negative effect on it? I'd like to be able to use the multi-channel analog input to directly connect a source with better quality DAC's for music listening, but if the R-972's circuitry on that input is then going to turn around and degrade or dirty up the signal somehow, it's kind of pointless. Thanks.
