I had the 950 for about 6 months. 1st a red dot (equivalent), had hiss; then a blue dot (equivalent), no hiss. Best experience with customer service I've ever had.
So why did I move on?
I set up (the latest version of) my system with Logic 7 in mind from the start. To be honest, I liked the 7.1 CES modes on the Outlaw so much, that I just gosh dern had to have the real thing. So the original plan was a used MC-1 plus a Sony TA-P9000ES 5.1 analog preamp. Talked to my dealer, and some of the differences between the MC-1 and the MC-8, and a good deal also, pushed me in the direction of the MC-8. Have had it about 4 weeks now.
Logic 7 is nice. A little bit more separation in the rear soundstage. But at least for me in my system, it's only really apparent if I'm actively listening for it. But it does add to the overall presentation. And the MC-8 is a whole lot more tweakable than the 950. But if you don't know what you're doing, you can really screw things up too.

The manual I got with the MC-8, is by far, one of the best manuals I've ever gotten with a piece of gear.
But to be honest, when I factor in the cost difference between the 950 and the Lexicon, and the fact that I couldn't really hear any differences in 2 ch audio, I was really surprised by how competitive the performance of the 950 was. *And*, I gave up the tuner in the 950 and analog BM on the 5.1 inputs too... I'll be keeping an eye out for the "big brother" of the 950 when it comes out, that's for sure...
