I got a M30 for my wife: she liked the PSB Alpha B speakers so that's what we got her.

The UD-M30 puts out 20w/chanel so both the M3 and M22 should be suitable as their min wattage is stated at ten. The M2 has a min wattage req of 15 watts so might be a little more problematical. When auditioning the system the shop was running it with Axiom M3's back when they still had a retail presence. Sounded awesome to me.

P.S. Long time lurker first time poster. We use M22's coupled to a cheap Technics SA-DX750 for our living room system: works great.

P.S.S. Thanks for all the great advice that I've read here over the last couple years.
