1. About an Emotiva XPA-2 (they're on sale right now), matched with an Onkyo TX-SR706 or a Marantz SR6003?
* When you say Processor, you mean on the Video side or Audio side?
2. If you meant both, then the TX-SR876 is the one. Mate this with the XPA-3 for a dynamite system (always good to give your three front speakers the same power from the same amp for a better overall balance and homogenity from the front soundfield).
3. Or about the new Pre/Pro from Emotiva coming soon, plus the XPA-5, also on sale.
As you can see, you have many options here. And your budget to consider, plus your room dimensions and listening habits.
