Yes, I know the 33's and 33H's well. They are exceptional amps that would mate extremely well with the MAXX 2's, as would a cornucopia of amplifier types, from single-ended to high-current solid-state.
I did not infer that you have to have tubes with any Wilson's to successfully match them within a system. However, my opinion is that the original MAXX's had a slightly more definable "character"-- cooler and less complete, less robust--less neutral than the more chameleon-like MAXX 2's-- again, referring only to tonal balance.
All speakers and components at this level should be carefully matched to the listener and his/her preference. The MAXX 2's performance simplifies such a process, as they should at their price. If you have the opportunity, I highly recommend seeking out a trial.
