Help My Krell amp is too big.

I am building a new home which will have a stereo cabinet to house my components. My Krell FPB 600 2 channel amp is too long to fit in my 22" deep cabinet. Even though I love the amp, I now need to sell it. I'm thinking about two smaller monoblocks to replace it. I don't want to go backwards on quality. Suggestions? I would like to spend less than 10K. Speakers are B&W Nautilus 801's and preamp is Krell HTS 7.1. Thanks!
