Tubes On Top Without Getting Ridiculous

The more I read about biamping Tympanis the more I am convinced I must be missing out.

One of the thing that bothers me, however, is the idea of some quirky, overpriced, expensive tube eating amp for the mids and highs.

So without

- going through hell for that last elusive bit of magic,
- without raising the temperature of my room by about 20 degrees, and

- without having to ship hundreds of pounds of fragile gear in for servicing blah blah blah -

- oh and one more thing without spending a zillion dollars....

What tube amps might I consider for workhorse performance, when using perhaps Bryston 7 monoblocks on the bottom with a Marchand or Audio Research crossover.

Thanks for any ideas.
