Best amp for Proac response 2.5


I need some advise, I'm using a Classe CA-100 ss now to drive the Proacs. It does just fine but I need more resolution. Any ideas without spending an arm and a leg? I would buy demo or used if in excellent cond. Thanks

I have them and run them with a pass aleph 3. widely considered one of the best amps made. It is small but drives them very well. Smooth sound, but plenty of bass punch! Highly recommended! Can probly pick one up used for $1000.00. Or even a aleph 5. It is the same amp just 60 watts instead of 30.
I use the Jeff Rowland Concentra Intergrated Amplifier with my ProAc 2.5 speakers. I suggest you listen and judge for your self. cheers.
