amp for vandersteens

I run my Treo's with Atma MA-1's, albeit with crossovers and Vandy subs.
I bet a pair of M 60's would be capable of driving the Vandy 2's, even without the subs. Unless you want to reproduce a rock concert.

I use Ayre with my Vandy 5A's ..  Im happy

Steve Mccormark mentioned before in the forums that people who own Vandersteen speakers report that the Mccormack amps can make them sing and perform as if they were made for each other. However they are increasingly becoming hard to find, but not impossible, especially ones with the upgrades.

Second the post above - Audio Research tube amp should be strongly considered.  Buy the best newest one you can afford.  Older ones are fine too if you are on a tight budget.  Vandy's need a little 'waking up' in my experience as they are voiced on the smoother side of the spectrum.  ARC amps will give you the tube magic but don't roll off much at the high end.
