Proceed PAV/PDSD v. AVP-2

I have a Proceed PAV/PDSD combination that I use with Proceed Amp 2 and Amp 3 to drive a pair of KEF 104/2s, a KEF 200 C center channel, and KEF 102/2 surrounds. A Velodyne HGS-15 handles the LFE. I'm very pleased with the sound of this system for both music and movies. It puts up a broad sound stage with precise imaging, and the sub integrates seamlessly with the other speakers.

Nevertheless, I suspect the DACs in the AVP-2 may be superior to those in the PDSD, and the AVP-2 may include other features that are of advantage -- a single chassis for one.

Has anyone out there compared the two, and would it be worthwhile to move from the PAV/PDSD to the AVP-2?

I have owned the Pav/pdsd and the AVP, not version 2. They are probably equal in quality, but the PDSD has identical "top notch available" dacs for all channels. AVP user interface is better.
