We've had several customers using our MA-2s. To use them with the speaker, you need a small ZOBEL network in parallel with the speaker but that is easy to do.
IMO/IME the speaker is not really all that hard to drive. The fact that it is omnidirectional means that the measurements on it don't show its true efficiency.
As a result most 200-watt tube amps will do fine in an average size room.
