Rob,
Yes, my home theater is separate from my 2-channel systems. I like to optimize things for each application whenever possible. Glad you like my antique "amp-stand" and your point about a tube amp being more appropriate makes sense.
But I just replaced the Klipsch with VMPS RM30 ribbon monitors and they seem to thrive on solid-state power and control. I may end up using solid-state on the bass section and tubes, or hybrid amps on the midrange/treble section. I want to have some fun trying some different gear with these new speakers, which appear to have the potential for greatness. Time, and some experimentation will tell.
In the video system I've replaced the Yamaha mains with Newform Research Module 30 Ribbon hybrids. They are less efficient, and have less bass, but they provide an extremely natural presentation. Still, I was thinking of going to a somewhat more efficient tower speaker with a bit more bass punch.
