The least expensive way to do what you want is to get a surround sound receiver that has preamp output jacks.
Use the front left and right preamp output jacks on the surround sound receiver to send a signal to a set of line level inputs to your present receiver (CD, tape, aux, etc. inputs). For surround sound use, the receiver is in control. Your stereo receiver is just being used to power the front L & R speakers.
For regular two channel application, use your setup as it is now.
If you have more money to spend, a 950 and a multi channel amp would be killer!
