The preamp was the Phasemation CM-2200. This is a passive preamp. It has both balanced and SE inputs. Despite it being a passive preamp it also has a switch in the back that allows for an additional 6dB of gain if needed. We did not use this at AXPONA.
Hello, We used the MA-1500's in the UnoSD room at AXPONA. It will fully drive the UnoSD. I also used the MA-1500 on my pair of DuoGT's and it worked without any issues. As the bass is fully driven by the built i amplifier there is very little stress on the partnering amplifier.
I should note that I did not listen to both the MA1500 and the MA2000 driving the Uno SD so I can't really comment on the sonic performance differences. The MA-1500 did have a sweetness that I liked at AXPONA. Both are going to drive the speaker. I just can't tell you which you might like better.

...I heard these Mezzo Duo G3s (think I have that right) in Singapore last week, and wow were they terrific. This was a used pair for sale. Sadly, the Trios were not being run, and as a visitor, I couldn't really ask how about it?! But man did I want to hear them!
