I had a friend whos had a nice system that started out with 200 watt monos on each side. He then got another pair of 200 watt monos, sent all 4 amps back to the factory to be "calibrated". The speakers dropped to 3 Ohms and were 91 db sensitive. It wasn't just an increase in volume and power, it was amazing how the speakers bloomed, the soundstage became more holographic and took on an effortless ease with the extra pair of amps. 1200 watts per side @ 3 Ohms into 91 db speakers. For the life of me I can't explain the gains in improvement. Perhaps the amps stayed in class A longer before sitching over to class AB?

Two of the three amps I ordered for my multichannel setup arrived today so I had to do a quick checkout driving the MG1.6 fronts and center. WOW. Everything you have heard about these amps is true. Perhaps, as others have said, they are particularly well suited to Maggies.
I did have a slight hum, as others have experienced, but activating the "ground lift" switch totally eliminated it. The amp is set up for balanced line input, and I suspect that the hum problem happens when you use a single ended input signal. (Not really a problem because the ground lift switch fixes it). The fan noise would be anoying if you can't put the amp in the cellar as I do. It is reported that in home audio applications you can disconnect the fan without overheating the amp. There is also a mod offered which replaces the fan with one that is much more quiet.
