The ARC amps make a lot more power than the ML2.2 and would suit a much wider range of loudspeakers. But if you have the right sort of speaker, there is something pretty magical to the sound of the ML2.1 (which I own), and I assume the ML2.2 is cut from the same cloth.
What speakers were you going to pair with the amps?
