I wish I could afford a nice outboard amp, as I do usually have my system pretty loud as I'm frequently in the next room.
Two quick points, though: I think John's note of their inconsistencies aren't surprising in that they DO sell amps.
Secondly, on a less "suspicious" note, they are also in the market for the professional, live sound musician, where the dynamic range can be quite a bit wider than the recordings most would listen to at home. And, as they correctly point out, it's dynamic range that really "hogs the watts".
