What gonk said about the "double bass" issue on the 950 vs the 1066.

Also, I had a 950 for 6 months. Liked it a lot. But I liked the CES modes so much, that it pushed me over the edge for getting a Lexicon MC-8 and Logic 7.
Here's the interesting part:
2 ch listening: to me, not much difference. I do slightly prefer the AKM DACs in the Lexicon to the Cirrus DACs in the 950. But maybe it's more of a "difference" than one being better or worse than the other.
As far as for movies, I do prefer Logic 7, but you really have to listen before the differences in the rear soundstage and spatialization become apparent. The MC-8 is a lot more tweakible. Kind of fun to play around with all the settings when you first set it up, but then even still just like the 950, you "set it and forget it" and just enjoy.
Don't forget that the 950 gives you an unconditional 30 day money back guarentee. Most Rotel dealers will not do that. And, you get the *transferrable* 5 year warranty too.
