With volume control on the TAD, there should be no problem in matching the amps. Put the SS amp on the bass and the tube amp on the highs, adjust the volume for a balanced sound (use familiar music to do this) and voila, you should be done.
Check out my system page - I do the same thing with my JM Lab Electra 926 and I love it. My tube amp has never sounded better!
The TAD will have plenty of power for 800Hz on up. No problem. My 40Wpc tube amp can rock the house and it powers 200Hz on up. As for a good SS amp for the low end, I would highly recommend a McIntosh. It should mate well with the sound of the TAD. The MC7100 is a cheap bargain and has amazing bass with two-settings for input sensitivity - might be a great feature for you. If you can afford more, get a MC162. These are my recommendations.
However, 800Hz is a very high crossover for technically-accurate horizontal biamping. But you might get lucky and have good quality sound anyway. Try it and see.
