I use a McIntosh MX123 pre-amp / surround processor with a BAT VK6200 amplifier. The processor selects the outputs according to the source and number of channels input. When I watch movies it’s surround sound, when I listen to music the system works in stereo. The BAT amplifier is really six, 180 watt, individual, independent, single-channel amplifiers in a card cage chassis. But, I’m satisfied with a mid-fi system. If you don’t need to play the extreme end of the audio world games, you can find a quite satisfying middle ground that will work for both video and music without needing separate systems. I know, on this website it’s total heresy...but someone had to inject a bit of sanity into the all-or-nothing approach to audio...
