You could save a bit and try the Revel F30, or the F50 for more slam. The B&W's hot tweeters are probably NOT a good match with Krells, I concur. The Aeriel 7b, 8 and 10t are all good bets, but I prefer the smoother mids of the Revel.
Take a peek at room treatment to reduce low-treble fatigue, too. Have fun.
