Best amp for Vandersteen 2sig


Hi, I am starting over with my system. I am considering going with Vandersteen 2sig. I have heard these at a dealer was very impressed with their sound and value. The goal is a very enjoyable stereo system without spending as much as new car would cost! I already have a Rega planet 2000, VTL 2.5 pre amp, Transparent interconnects and speaker cables, and Richard Gray 400 power conditioner. I am cosidering a VTL ST85 (about 80w per ch) because this really fits the budget. But is this amp enough tube power to drive these speakers? I like to listen to Jazz and Rock, not A/C D/C at 120db but more like Steely Dan at low to moderate levels.
Thank you for your suggestions.

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.
I think you will find a lot of consistent advice regardign ARC, Quicksilver, and McCormack running with Vandersteen. I storngly secong the 2Wq recommendation, especially with the tubed units.
