All I'm gonna say is the HD800 vs AD2000 is NO comparison in terms of technical quality. The only reason anyone would prefer the AD2000 would be due to sound signature/coloration. IMO the HD800 is just stunning for acoustic (and pretty much anything else). The AD2000 was very good, with technical quality about the same level of the HD650 IMO, but a distinctly different sound signature obviously. The HD650 has a midbass hump which the AD2000 does not have.
In terms of impact, I find the HD800 to have much more bass impact than the AD2000. The HD800 has always impressed me with its bass impact even vs. the HD650 (therefore even more vs. the AD2000), but I typically define bass impact in the sub-bass range. If you like midbass, go for the HD650 -- the AD2000 is great for mids but lacks midbass vs the HD650. If you like flat with a touch of treble, go for the HD800. The AD2000 as I see it is a sort of hybrid between the HD800 and HD650 except that it lacks sub-bass and lacks the detail of the HD800 by a huge margin (again, the AD2000 is about on par with the HD650 in terms of detail, no more).
If I was to chart the sound signatures vs. my ear's interpretation of "flat", I'd put the HD800 at dead neutral except a few dbs more treble, and the AD2000 at neutral but lacking some deep bass (20-40hz) and just slightly less upper treble than what would be optimal.
