Looking for a 7 channel power amp to replace Krell showcase 7

I am using Krell showcase 7 now with good result in my HT. But the amp is like a grill during summer, it heats up my basement. There is also some reliability concern about this amp. I am looking for some 7 channel amp that is comparable to Krell to replace my showcase 7, which will not generate that much heat. I am using Krell S-1000 processor in HT setup with B&W 805 speakers. Balance input is preferred but not must. No fan in power amp please.
