New amp? Thiel...

Bought a pair of Thiel CS2.4's about 6 months ago and they are just as amazing as the reviews say. I'm driving them with a Krell KAV-250a, which has plenty of power but somehow I'm wondering if there's not a better amp for the Thiels...

The rest of the system includes a Krell HTS7.1 (need to maintain the HT/2-ch in one room, so not much of an option there... besides the analog pre of the HTS7.1 is pretty darn good), a Clearaudio Champion with Benz Silver MC, Graham Slee phono stage, Oppo BDP-95 (xlr analog) and all Cardas cables. The room is pretty much a concrete bunker... basement with carpeted concrete floor, concrete walls with drapes on the walls (basically thickish cotton/synthetic blackout curtains), so it's a pretty bright room. I know I need to add some acoustic panels to it, that's on the list.

I've heard the Thiel CS2.4's with a very large (and out of my price range) McIntosh (MC1.2k) and that's an amazing combination.

I would sell my Krell (seems to go for $1100-1600 depending on condition lately) and I would add another $500-1000 to that...

Any recommendations where to start looking?
