I an effort to improve upon the performance of my system in stereo, I am looking at inserting a Proceed Pre downstream to the A1SR. The proceed has a loop which then allows passage of the signal for movies through it, but the CDP will be hooked up directly to the Proceed and from there to the power amp. I guess what I'm really asking is whether the two channel performance of a dedicated preamp(in this case the proceed pre) will surpass that of the Denon. Thanks, George. P.S. I really need some help here, as I have come upon a decent priced Proceed PRE.
