Im not interested in 2 channel audio Just yet , im interested in adding a dac just to play music over center channel music mode , I just dont know what the receiver does with this analog finished signal once it processes it , would it be better in any way or is a Dac like the Denafrips ares2 reserved just for 2 channel. I called crutchfeild they said yes it would help but he didn't sound to sure of himself . Im asking this because in the Ares the ladder dac has a ladder for each channel so the left and right RCA gets amplified as is , but if Im asking an AVR to process this signal thru 1 channel in music mode , Im looking for an improvement or is it a total waste of time?
