Best amp for Vandersteen 2sig

I also have the Vandy-2sig's and am using a McCormack DNA225, which I find to be a good match. Prior to the McCormack I had a ARC VT-60 (50 tube wpc) which I enjoyed but had limited capability to control the speakers at moderate to high volume levels. At lower levels and with Jazz, female vocals, it was great.

You should consider a Vandy 2WQ Sub, which will improve system performance. I added mine while I had the VT-60 and it was a significant improvement. I lived with that set-up for quite a while and then decided to try the McCormack. I had both amps in my system for about 3 months and ultimately chose the McCormack for it's comparitively effortless control and greater dynamic presentation.

My 2ce Sigs really sing with my ARC VT60 (50wpc). My room is not huge (10 X 25 feet), this amp has plenty of power to play at high volumes.

Avoid any amp that is warm and slow. The already uninvolving Vandersteens will probably lull you to sleep. Look for something with some snap and zip, the McCormack recommendation seems logical.

I have 2cesig and had a adcom 5503 it was ok, I went to quicksilvers v4 wow these are a good match. The speakers handel detal really well so look for a good clean amp and try it I can barly hear the noise floor. Tubes really shine with vandies because they are so transparent. Now I am looking a the 5a so if you are in nj looking for a 6 month old pair of 2 ce sig let me know.

I have buddy the has a pair of the 2ce sigs and drives them with Rouge M150's. It is very nice and will play as loud as you want without losing control.
