Thiel 2.2, whats a good amp for them?

I have a pair of Thiel 2.2s that I like quite a bit. I have a Sonograph SA250 on them now, and have an amp upgrade bug. What's a good match?
Krell KAV 250a at least or if you can afford the FPB series that will be better.
happy hunting
I used a Mark Levinson No. 331 with 2.2s with outstanding results. I have never heard a pair of 2.2s sound better.
any good tube amp rated at 60-100 watts the thiels seem tohave tendency towards brightness in the 7k region and tubes wil tone it down a bit
