Moto Man
I have done this for years. I have the stereo outs from the processor go into a tube preamp. The tube preamp has two sets of outputs, one connected to the multichannel amp and one connected to tube mono blocks. The preamp is set to unity gain when listening to surround sound. When I listen to stereo you do have to switch speaker cables from the surround sound amp to the tube mono blocks and make sure the surround sound amp is turned off as my speakers do not have two sets of connectors. To some people this may be a pain in the rear but works for me.
I really do not have another choice as the room is too small to have two separate setups.
