I am a big believer in Krell, and thusly believe you would be better with the Krell.
If you are actively bi-amping, my answer might be different.
I would, if you can afford it, see if you could swing for the FPB series. The FPB's are much smoother on the top end.
I use to use the KSA300S to drive my B&W800s then changed briefly to the FPB300. WOW, what a difference. I now use the FPB to drive the mid/highs and the KSA to drive the bass via the Krell KBX electronic crossover. The total improvement although very expensive upgrade, was worth ever penny and then some.
Good luck.
