For Processor, I would go with either the Denon X3300 ($599) or the X4300 for $799 brand new from Amazon Prime.
Best Buy could also price match Amazon.
For amps, there are many choices - Outlaw, Emotiva, Monolith, ATI, etc.
However, I think you should just use the AVR alone first. If you hear any distortion, then you can always add the amp later.
