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
