Preamp suggestions needed

I am trying to decide on a preamp to go with my Conrad Johnson MF-2200 amp. I also have an Adcom 3 channel pre/pro/amp to run center and rears fot HT. If I understand correctly, I need a preamp with a processor loop, which is what I now have(Adcom GTP-450). I have been so impressed with CJ amp that I would like to have the CJ PFR pre mainly because it is set up with a video loop. However I don't know if I can afford it. Have also considered the Adcom GFP-750. A used one is more in my price range and also has a processor loop. What are some other alternatives for under $1000.00. Would also like a phono stage if possible. Though I don't have a real high end turntable it might be fun to listen to some of those RCA "Living Stereo" albums through a great amp and preamp. As always your advice is appreciated.
One more question: If I get rid of the 3 channel pre/pro/amp and get a 5 ch HT receiver how can I arrange it so I can use my main speakers for the fronts and for stereo also? Is that done through a speaker selector or do I still need a processor loop and just run 3 ch of the receiver for center and rears? Thanks again
