You're right Kr4, but it doesn't have the by-pass so I'll have to pursue other options. Steuspeed, originally what I had in mind was to reinstall the B&K as a parallel system using a speaker switching panel allowing the fronts to be shared. This would allow me to maintain the two channel integrity of my current system but it further complicates its use for others that I share this setup with.
Coincidentally, I originally had an all ML surround setup including the center, rears and sub, with Odysseys as the fronts. Before I abandoned surround a few years ago, I had replaced the rears with in ceiling speakers and sold the ML center. I still have the sub in storage as well as a Focal Electra center speaker. I traded the Odysseys for the Ethos pair several months ago so I won't have to spend a lot of money on speakers to have, one way or another, a workable surround system again.
The easiest solution would be to ditch the Peachtree gear which I very much like, and purchase a quality HT processor/amp with the capability for high quality music reproduction. This takes me back to the original purpose of this post which is to identify the best surround equipment to satisfy that goal. I will still be using the Nova for music sources.
