Magnaplanar is 30 minutes from our front door. Over the last 30 years we've had a lot of experience with them. In fact, our first prototypes were used immediately on Maggies as that was one of the speakers we were using for reference (Tympani 1Us -that was a long time ago...). Jim Winey has made a point of telling me a number of times that the best he ever heard one of their speakers (MG-20) was with our MA-2s.
I've seen people with our amps have the tubes last a long time. One guy here in town has had the same set for the last 8 years. If using M-60s, most everyone also uses a set of ZEROs. The amps then make 80 watts and run cooler, with greater authority and transparency, and the tubes last longer too.
Its true that if you put a powerhouse 600 watt amp on a speaker like this it will play a little louder, but you will find that at higher volumes the dynamics are compressed due to the phenomena I mentioned earlier. BTW this is not true of the push-pull speakers! I regard the 20.1 as one of the better bargains in high end audio, but this thread is with specific regard to the MG-2.
