I finally got around to buying this upgrade and installing it. Re-ran Audyssey and confirmed settings with a meter. I typically run with Audyssey enabled, but with R/L bypassed. I still prefer it this way with the upgraded programming. The dynamic volume is way cool, but I’m not sure what the dynamic EQ is supposed to do. This is most likely wishful thinking, but things do sound a bit better to me. Bass seams to be more defined and the mids/highs are more airy.

I don’t think it was worth $100 though. If anyone is on a tight budget, you could find better things to spend $100 on than this upgrade.
