Very interesting, Eric. I also have those three ambience processing modes available and in the past have investigated them comparatively, but in a much more casual manner than what you did. The result was that I use the DPLII nearly all the time for everything, but do make some adjustments on the center width and dimension parameters. You didn't comment on those, so I wonder if they were part of your DPLII analysis.
Your report re Neo:6 and solo instruments probably will inspire me to check out that particular combination more closely. I listen to a lot of solo piano, and I'll fire up my favorite Albeniz Iberia and some Debussy Images when I get a little time.
