Got a little antsy, so I dragged out my variable AC power supply and dialed it into about 50V AC to test the amps. I will say this... IT GETS LOUD! The sound seems about the same as the AVR-3806, but its hard to say because I'm just running one VP150 at a time. I hit 104db (@ 1m) constant output with the iPhone turned all the way up, and was pulling about 50W. Amp IC temp hovered around 56C (that's the actual chip, not the heatsink which was only warm to the touch). But just as I was typing this mail, the toroid arrived! Will be away for a bit doing some rewiring, but looking real good so far. Pix attached:

Toroid!
