Obviously, IIx only becomes a factor if you are running seven channels (which I've now been doing for a few months). I personally don't feel that I'm losing out by using Cirrus Extra Surround in lieu of Pro Logic IIx -- CES does a pretty respectable job with the surround soundstage. Even with seven channels, I think the effectiveness of Cirrus Extra Surround along with the 950's price tag makes it difficult to recommend choosing one of the newer Pro Logic IIx pre/pros (at roughly double the price) over a 950 purely based on that feature.
