Worth Upgrading?

[GAWD]

I've got a Pioneer ELite VSX-01. I don't use the amp section since I've got an Emotiva amp running my speakers. My question is this, is there any benefit in upgrading the receiver say to a SC-07 or Marantz AV proc or an INTEGRA DHC-40.1?

I have all the HDMI inputs I need. I don't use any of the video processing AND I'll be buying a DVDO product in the future.

I've read all I can on MCACC vs Audessy and it seems like they both do the same thing, and i've got my subs EQd already.

Besides being able to set the crossover on each speaker in some of the newer units, am I missing anything in going to another unit?

Maybe even a UMC-1?
