Amplifiers and Dynaudio C2 signatures

I'd get a better pre. I think Pass goes with either a Pass pre XP 20 at least or a tube pre like Cary SLP 05 or ARC Ref 5 SE at least.

I`d have to sell my pre also. Its like new, maybe 50 hours at most. 

I will see if I can sell it first, I bought it new with the arc from Anthem. I have read good things about the Moon 860A and pre740A? I will also check out the IA. I want to have the current and power to push these if I want. I`m not sure the IA will do that, or I`m lacking knowledge of them. Let me know your thoughts. 

The other brand that works quite well with Dyn's is Karan Acoustics.

Gives a very musical full bodied sound and holographic imaging.
