Amp recommendations for Revel Salon2

Just recently purchased a pair of Salon2's. I've been very happy with these speakers but I know they can sound better with better electronics.

At this point, I'm using Oppo 83SE (CD/BR), Anthem AVM30 (Pre-pro) and MCA 50 (225 w/ch X 5). My plan is to upgrade the amp first and subsequently the pre-pro.

I'm considering the following and, frankly, open to suggestions:

- Audio Research DSI 450
- McIntosh 402 or 303
- Parasound Halo
- Classe

I use the system 70/30 music to video. Therefore, my top priority is musicality.

Appreciate comments/recommendations.

Thanks,
Mike
