Best match with Proac Response Series

Thank you very much guys for your responses.
I finally bought the Audio Research Integreted CA 50.

THANKS AGAIN

Awesome Dominic! Have fun!

As you may gather from the foregoing, ProAcs will change depending on what you feed them. I have found them sweet with Pass Labs Aleph 3's, aggressive with ARC VT 100 II's, lite 'n' livley with C-J Premier 12A's, delicious and holographic with Blue Circle BC 2's. And with Cary 805's they are alleged to have gotten into some folks' pants. How do you like your eggs?

I heard Audio Research electronics an Tara cables with the 2.5s, and it was amazing. Forget the subwoofer, and keep it as simple as possible. I understand that the designer of Proac speakers voices them with Audio Research tube electronics, so I would imagine it is a good match, as my ears confirmed for me.

I own the 2.5's and the absolute sweetest sound I've ever heard was the 2.5's coupled with a Cary 300SEI and synergistic cables throughout. Currently Im using Cary Monoblocs but the 300SEI is an absolute musical experience with these speakers. all 11 watts of it.
