McCormack would defintely light up the Vandersteens, with say a Rouge 66 pre. But I personaly would try to find a Classe 100 watt amp if there was one available. It won't be easy as I see very few pass through audiogon.
You didn't mention your source? Tubes can play loud, if you like mid-range you may consider going with a tube pre. If you talk to Richard Vandersteen, he will steer you in the direction of tubes. I remeber a conversation I was having with him in which I told him I was switching from my 60 watt tube amps ( on 3a's ) to a 200 watt SS amp. He was not in favor of the move at all. To the best of my knowledge Vandersteen tests there speakers on Quicksilver Audio amps. I'm sure someone will correct me if I'm wrong.
But still without spending time with your listening experience, it's hard to say from here what will work.......
