Which amp for Vandersteen 3As?

That leads me toward the B&Ks, especially the 200.7 - it fits that general description to a T. Even though it is a multi-channel amp, it sounds very good in the stereo mode. The 3A Signatures are no doubt a superior speaker, but I am getting these mint condition 3As for only $800, so I can't complain or lust after other higher-performing choices. Thank you for your insight/input....it reinforces some of what I intuitively felt after hearing the 3As.

That leads me toward the B&K 200.7, which even though it is a multi-channel amp, sounds very good in stereo mode. It can seem a little forward at times, but that may be a good thing with the 3As. It definitely has sufficient power to drive them. I really can't complain or lust after higher-performing speakers since I am only paying $900 for the 3As, especially since they are
literally mint condition cosmetically.

At one time, years ago I traded in my Vandersteen 2ci Speakers for the 3A Speakers.  I drove it with the McCormack DNA125 amp And it seemed to be a perfect match.  McCormack is much more high end than B&K or Adcom and is much better sounding as well.  

I ran my 3a sigs with an unmodded Adcom GFA 555, then a McCormack DNA-1.
Both provided a great sound.
The nice thing is that SMc Audio can upgrade the DNA-1's to whatever you want. They converted my DNA-1's to monoblocks, as well.

If you want to get the most from you Vandy's, I suggest going with either Ayre, Belles, or Atma Sphere (tubes). 
Trust me, I tried everything...
Also, when in doubt, PM John Rutan (audioconnection) for the best Vandy information.

Thanks for the tips, Bob.....from the responses so far, it looks like the 3As will sound good with most amps, but will perform best with modded versions. I'll probably look into having the DNA-125 upgraded since that is the best all-round amp I own. I'll try a couple of my amps with the speakers and see how that goes. My opinion is that I can't lose either way, just make things better.
