Morty74,
I second Dbphd's suggestion that you sell your Marantz 7705 and run all Oppo outputs direct to your Rotel. I found I liked the sound of my system better, for both ht and 2-ch music, once I eliminated both my Parasound AV2500 preamp/processor and my VTL 2-ch preamp. I use the 'Dedicated Stereo' xlr outputs to go direct to my front L+R front channel amp and the rca surround outputs direct to my surround amps.
If you're unsure, just try your system with and without the 7705 and let your ears decide. The direct method will be very neutral and without coloration which may or may not be to your liking.
The only reason you may not want to use this method is if you have multiple sources since the Oppo has very limited inputs.
Typically in audio the simplest, shortest and most direct signal chain is preferred and will tend to sound the best.
