Pairing surround processor with tube power amp

Does anybody here has experience pairing surround sound processor, such as Krell or McIntosh with tube power amps? I am currently using CJ Premier 12 monoblocks with JM Lab speakers. In stead of connect a HT multichannel amp bypassing the stereo pre-amp, I am wondering what will happen if I just use the surround processor?

Thank you!
Thank you guys.

Seems there are always two ways to look at this. I probably shall get some equipments from dealers and try them.

Any body tried Krell?
Hi. I had a pair of Cary/AES EL34 monoblocks powering my front speakers, fed from an Anthem D2 processor. Worked great, sounded great.
Thank you goatwuss. I am also thinking I might get something out from the DAC in a good processor. I probably will try a Krell this weekend.
