How do ARC's latest amps stack up to Lamm?

I own the M2.2 LAMM rated at 220WPC. Stereophile measure the real power
on a bench test at 300WPC .So honestly this model got "balls"
and was driving effortless my former ANDRA 3 speakers and actually my
SONUS FABER EVOLUTION. From what i heard with ARC product i do think
that the LAMM products offer a more delicate sound by a good notch. My
humble opinion..... + the M2.2 are not full tube but hybrid design offering the
best of both world: GRIP and FINESSE

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?
