Recommended 5.1 processor + amp under 10k

Ditto. Keep the amps; get the Foundation.

Thanks for the recommendations. Krell also advised me to keep the amps, maybe get them serviced and upgrade the processor. The Foundation offers more features than I need and I am wary about not licensing Audyssey. Will also look at Anthem and Classe.

Decided to go with NAD separates, bought demo units at a dealer and spend some good money upgrading the cabling system.

Have put the KAV250a and KAV250a/3 up for sale

Onkyo PR-SC5509 without a doubt, the modular chassis beats the Integra counterpart, also for modern features beats anything else. I use it with a Classe CP-700 on the fronts, the 2-channel balanced Marantz UD9004 feeding straight to the CP700, and the 7.1 single ended King Cobras in bypass through the Onkyo, decoded superlatively again in the UD9004. The beauty of the CP700 is that it allows passive biamping of fronts on my PR Signature 8 v2 system, for which the two monoblock construction Sherbourn 5/1500A amps do well. Of course these amps are the weak point, looking to to get Classe 100lb monoblocks for the stereo, but OMFG, I will need speaker switchers, so keeping it simple for now. The CP700 breathes life in all sources as it operates in passive line level mode when the PR-SC5509 is on, further widening and claryfying the front stage in that neutral Classe way that is so great.

I would try out all the ones with room correction software and EQ and buy the one that sounds best.

For example, Audyssey XT32 + dual Sub EQ + Dynamic EQ.

Or Anthem ARC or Trinnov, etc.

I would not buy anything that does not have some kind of advanced EQ. You never know when you need it.

I've been through comparing Direct/Bypass vs. EQ, and EQ won.
