Jdub,
Analog Direct kills the digital cross-over and directs all bass to the main speakers. The Pure Audio (sic?) mode kills all video DSP. The idea is to re-create a minimalist 2 channel high-end system.
I found that it works pretty well. However, your main speakers must have sufficiently wide bandwidth (or your preferred program material must have sufficiently limited bandwidth) to justify killing the subwoofers or this mode will probably make little sense (to me anyway). If the bottom octaves don't matter - for either of those reasons - then it comes down to Audyssey or no Audyssey. I like the former in most every set-up that I've heard, but YMMV.
When I was comparing more expensive and less expensive pre-pros, I suspect that the performance of the DSP software dominated my own evaluation of the listening experience. I preferred Audyssey XT32 to "lesser" Audyssey versions, but not dramatically. The Meridian and Anthem alternatives did sound a bit different from high-end Audyssey equipped models, but in both cases, I found the delta pretty subtle.
My take-away: spend up for the XT-32, but not more than that.
As always, YMMV.
