How many tube watts for Vandersteen 2's?

I also heard the Vandy's at AudioConnection in Verona played by John Rutan! One of the best sounds in a dealer showroom I have EVER heard. Played a Terry Evans CD that just sounded so alive.

I used one of these 25 wpc in a room bigger than yours:

It's really more important that you have some current behind those watts. For example, you could use a pair of Dyna MKIII's but you won't like the way the bottom end sounds. Sixty tube watts is sufficient if you don't play your music loud. Just use a tube amp that has some decent energy storage. Most of the ARC amps do. Roger's amps do as well i.e. RAM Labs/ Music Reference. Just remember, current controls the bottom end on dynamic speakers.

Yes the VTL IT-85 is sufficient.

I am using 2cesigs with a Music Reference rm9 mkll and I couldn't ask for better. The bass is as much as I could ask for. The Rm9 is the only component I never think about changing.
