Get a good transparent pre-amp to put between your processor and front L+R channel amplifiers.
Connect your CD system to one of the inputs, and your processor to another set of the inputs. Then connect the outputs to your front L+R channel amplifiers.
You now have your processor for multichannel sources and a pure two channel system in one.
Only hassle is setting the volume to zero gain when you select the processor input.
