tube integrated for Vandersteen 2's

I know I'm taking this conversation even more off-track...

While I agree that, in general and without knowing more about your system, room and preferences the Vandersteens are too much speaker for your room (I went with Green Mountain Audio speakers over a set of Vandersteen 2ce Sig IIs for this exact reason) you may want to think about acoustical treatments before getting on the equipment merry-go-round.

Acoustical Solutions

A set of 2' x 4' x 2" panel at the first reflection point, a 4' x 6' x 2" panel behind the seating position, and 2 (4 if you can do it) corner-mounted bass traps can do wonders for a small room.

I promise you...this will be a far better $1000 upgrade than any equipment purchase. No, it ain't sexy, but it's *soooo* worth it. If you've done this already...you already know what I'm talking about.

What are you using now as an amp / pre-amp / integrated?

I believe the 2ce Sig IIs will integrate at a 7' to 8' listening distance. Sufficient absorption behind the listening position will (effectively) increase the size of the room, and will allow you to sit closer to the wall (assuming you've also managed the low-end frequencies).

Assuming the speakers are positioned along the 8' wall, are out 2' from the rear wall, and the listening position effectively places the listener out 1' from the rear wall, you can just make it work.

However, your point is taken, and again, is part of the reason why I personally went with 2-way Green Mountain Audio speakers, and augmented the low-end with 2 subs.
