tube integrated for Vandersteen 2's

I'm not sure the problem is simply room reflections and bass traps, I'm not sure the room is big enough for driver integration. John Rutan from Audio Connection in New Jersey would probably be the best person to ask, I suspect he has sold more VS speakers than anyone in the country. The room/speaker interface is so much more important than the amp in terms of priority, that I would not spend a dime on an amp till I was sure the I got that part of the equation right first.

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.

Sorry, I was away. I'm using a YBA 2 pre/power. I have a SOTA Stsr/ SME V Grado Master. I use a Mac Mini Wavelength Coscecant Dac for digital. The room is much larger 12x 26 but the listening area is only 12 x 8. The speakers are on the long wall 2 feet in and the listening position is 6 feet from the speakers. Tapestry on wall behind the listening position. Can't listen loud NYC co-op. I'm happy with the speakers in general the question was about trying tubes over my SS YBA stuff for a change not changing speaker or room treatments that will have me living in Central Park after my wife throws me out.

Ah, Well then, Rogue or ARC integrated would be good choices - 50-60 watts should more than adequate power. The Rogue gear appears to be particularly good value, and I don't like the look of the ARC integrates (I like knobs to control functions) but that is a matter of taste.
