I'm not sure this is a strong plus as implemented.

The obvious one is the flexibility of separates - amps are much more stable technology than the processor, and in any case they are logical candidates for decoupling. If you need more amp, no problem. If you want to get newer processing modes or whatever, no problem.

On the minus side, some have commented on the 950 having a less than perfectly polished user interface and set of 'convenience' features, like relabelable inputs, per-mode trims, etc.

I'm not sure what subset of that the competitive receivers would implement though.
