The 950 includes several processing modes not available on the 1050 (DTS ES, Pro Logic II, DTS:NEO6, ...), more robust bass management (three separate, independently adjustable crossover points rather than one adjustable crossover on the 1050; an analog 80Hz crossover on the 6-channel analog input), stereo bypass on any analog input, and component video switching. It also adds some sonic benefits, partly due to having the amp section removed and partly due to a better design. The 7100 also offers more power than the 1050. With separates, you are able to completely isolate the high-power (and therefore high potential for interference) power amps from the more delicate signals in the preamp. Plus you can replace the preamp when technology jumps ahead while keeping the amp.

Seven speakers is the standard for EX/ES -- it takes the traditional 5.1 layout and adds a pair of surround back speakers. With almost all processing modes currently in use, those two speakers get the same signal, but having two of them provides better imaging and allows for future processing to give them discrete signals.

The 950/7100 will generally sound better than a $1000 mass-market receiver. The separate amp will provide more power and greater headroom for the speakers than a receiver's amplification, particularly with difficult loads like 4ohm speakers. I'd say that the 950/7100 would be a very good match with Adire's speakers.
