“The power amplifier is, well, a power amplifier. Aside from a large front-panel meter, with some fun color options, it has no special controls. The only practical feature I’d flag is that the amp has XLR inputs only, but few audiophiles today are going to use RCA cables in any case. Like all good power amps, you put it in place, hook it up, turn it on, and forget about it, although you will want to run a mini-cable between the preamp’s 12V trigger output and the power amp’s trigger input so that the amplifier turns on automatically with your preamp.
This is not just an ordinary power amp, however. When D’Agostino uses the word “power,” he is not kidding. The Progression stereo power amp is a 125-pound unit that can deliver 300 watts into 8 ohms and 600 watts into 4 ohms. Its gee-whiz technical features include 42 output transistors, a nearly 3000VA power-supply transformer, and 400,000 microfarads of power-supply storage capacitance, and it can optionally be hooked up to a 240V AC socket.”
