Now you didn't ask that question with cost constraints
I can totally see going hybrid in the case of the thiels. In my experience, tubed amps just don't do very well with thiels. Jim Thiel uses the new MF KW integrated at home (big power), which I think says it all. I assume your Thiels are similar.
I don't see anything wrong with going hybrid. Of course, you could sell the Thiels... hehe but that's another day, another battle
