What type amp to drive proac response 2.5

Its a tube-friendly speaker. 60 watts is a nice power with them too. We've had lots of customers using 2.5s.

What is your budget?

I am using Quicksilver V4 amps to drive my Proac 2.5 and I am very pleased with the results. You can see my system on Audiogon.

I heard them sound great driven by ARC electronics

Budget right now is around 2k on the used market . But i almost spent 3k on a pair of Atmasphere monoblocks but was too late on making a decision and they sold. In the distant future i plan on getting some ARC gear but not quite in the budget yet .
