It is a beautiful powerful beast. The company did not give away 10 devices to 10 people who know jack squat but that prevented a hype train. I am now driving the train happily. It is very powerful, has a huge screen and the sound is superb. Am still getting used to the Senn. The bass boost is subtle. Well done. With the bass dial all the way down they are pretty much studio cans it seems The ARM2 is the real deal. Love it.
