You have been clear that it is solid-state that you want, but is this because you envision buying an inefficient speaker like the mbl's? I ask because there is one tube amp that works particularly well with the big mbl 101, the CAT JL-3 (or the predecessor to that amp, the JL-1).
It is a very unusual design that was designed around the mbl 101 and that competes very favorably with massive solid-state amps. Here are a couple of links if you are interested:
