I'm amazed that this relatively small amplifier can output such an amount of power without breaking a sweat, it doesn't even get hot to the touch! Class D is the way forward for amplifiers, no doubt. Completely transparent sound, no distortion or coloration.
A few small nitpicks: the feet of the amp slide around quite a bit, they are not rubber-coated. The rear panel is quite cramped, making it difficult to swap cables. This is a side effect of the small size of the amp, so it's understandable.
