Mac 252, 353, 402?

HI -- I've been mulling over these amps and was just wondering if someone out there has had experience with all three. They will be driving a set of Harbeth Monitor 30s (not the most efficient things in the world).

I was initially driven toward a MA-2275 (that's what started the whole mac madness) but, alas, with little children around, my house is not the most tube-friendly environment.

Ideas, thoughts?
