what the best amps run revel salon2 stronger bass

With most music I've been very happy with the bass output from both amps I've used with my Salon 2s (first a Plinius SB-301 stereo amp and now Symphonic Line Kraft 250 monos). On those occasions I crave more bass - maybe 5% of the time - I think about adding subs, not changing amps.

But you do need to provide more information for us to help you. What are your room dimensions? Are there a lot of windows? What amps are you using now? What amps did you try and not find to your liking? Are you still looking for stronger bass response or is there something else you are looking for now?

I've never heard of anyone using Accustic Arts amps with Salon 2s.

Your post suggests you find the McCormack amps too polite so far. I found the same thing when I heard the Salon 2s with Mark Levinson amps. If you are looking for punchy, dynamic sound then I'd follow George's advice and look for amps that output high current and have fast rise times.
