So it looks like the HD850 does not do SACD/DVDA, and doesn't offer DVI output.
Also interesting, the HD950 is now a black over brushed aluminum look. I did a search for estimate prices, the 950 was just under $400, which is more than twice the HD841, so it better be improved (though the price will go down alot eventually)
I was thinking of just picking up the HD841 on clearance
