My CD player (sherwood newcastle CD980) has a variable output. I plug this straight into the power amp RCA's on a NAD 3150. This way I can use the remote volume control etc. But doing this i assume that i'm using the pre-amp in the CDP.
Of course the alternatitive is to use the fixed outputs form the CDP and use the Nad's pre-amp (i'm starting to lean this way now).

What would you do?
