If your budget will permit, I'd try the Berning ZH270. It will drive your speakers very well and has the some of the best sonics at any price. Your Vandersteen 3A's will literally sing like songbirds!!

Good Luck,

While I have never owned the 3's, I have owned 2 pairs of the model 2 speakers.
I did once drive them with a 30 watt tube amp, but this was in a small (12x15) room. When I moved them into a 12x26 room, the amp did not have enough power. Bass and highs were rolled off and when I push the amp too hard, the sound would distort and soundstage would collapse.
That said, the 3's need more power than the 2's. If you want tubes and they sound good with tubes, I suggest a pair of the Quicksilver Silver 90 monoblocks. You will have to hunt or wait for these to come up for sale, but you will see them from time to time.
i used a small 20-30 watt amp with a pair of Vandersteen 1-b's and it sounded pretty good at low volumes. Then one day i had it cranked...sounded great. Then the amp clipped and it sounded expensive. get a bigger amp
Also agree with Todd Philefreak: low power amps have caused an awful lot of blown tweeters - while going the other way (more than rated power) rarely results in problems when applied judiciously.
