Speakers that are matched well with Krell

I am looking for new speakers. My system is as follows. A Krell KRC-HR for a preamp, KAV250a for the amp, a KAV 300cd for my cd player, Nordost Red Dawn interconnects and Nordost Blue Heaven for my speaker wire. I am using Sonus Grand Piano speakers now. These speakers are from my dedicated home theater and I want to keep them there. Any opinions would be welcome.
