Krell is a great match for Thiels. I had a recently re-capped FPB 300 matched with Thiel 2.4's and was very pleased with how the Krell took over those 2.4's. Pronounced bass, good separation, just absolute control of the speaker. The 300 wasn't quite enough for the extremely demanding cs5's, but I really think you would be in good shape with the FPB 300 and the 3/6's, as they have a tough load, but not approching the cs5's.
I sold the Krell & replaced it with a CAT 600.2, a beast with 1200 wpc into 4 ohms; it brought out the bass, but doesn't have the defined middle and highs of the Krell.
Just my experience!
