Which Amp for B&W N803


Which will be the best Pre/Power goes with my N803.

Current Source:
CDP - EMC1
Cardas golden cross cables

Listing mainly Jazz & Classical. I have been considering the Jeff and Spectral, is it a good match?? Do I need to look for high power amp >200W?

Thanks!

I've heard a BAT system that sounded great with the 803's. VK-30 pre amp and VK-200 power amp.
With the N803's I had used a Mark Levinson No.383, BAT Vk30 pre/Vk200 amp and a Jeff Rowland Concentra II, the Concentra II was the best by far, not even close; furthermore I felt this was a great match.
