Keep the receiver, buy seperates (or an integrated amp) with HT bypass. Connect your CD player to the new pre/integrated, connect yout HT source to the receiver, power your mains from the new 2-channel rig, and Power your center, surrounds and HT sub. from the receiver.
I use this setup (Arcam Alpha 10 integrated/Denon AVR-3300 receiver) and it works great. You can do this without an HT bypass by just running the L&R-front pre-outs from your receiver into an unused line level input of the new pre-amp. You will have to use a "pre-defined" volume setting on the pre-amp.(maybe Top dead center?). It will work fine that way, but isn't as "elegant" as using an HT bypass.
