AVR in a HT Bypass setup

A while back I separated my HT & 2-channel setup after discovering HT Bypass.  I have a Parasound Hint6 powering Kef LS50s for Left/Right/Sub channels only and the AVR doing the rest of the 5 channels (Center, rear surround, L/R ambiance channels).  

My Pioneer 1120K is a bit long in the tooth and I want to upgrade to something with better calibration - especially for 2 subwoofers.  

Thoughts on where to look?
