How to access power amp section of integrated amp

Hello experts,

Is it possible to connect a surround processor's pre-outs to the power amp section of an integrated amp? If possible, could you recommend some integrated amps for a pair of Vandersteen 2Ce Sigs?

My goal is this:

For 2 channel music, connect CD player ==> Intgrated ==> Speakers. No other sources will be connected to the integrated amp.

For movies and home theater stuff, connect DVD Player (or other sources) ==> surround processor (use preouts)==> power amp section of integrated ==> Speakers.

Thanks,
Dustin
