tube integrated for Vandersteen 2's

I agree, there is a way, but tough without some knowhow on how to deal with the issues, I'd rather get a speaker better suited to the space, a high quality monitor from Harbeth or Merlin for example.

I think Ddd1 is right, unless you are planning a different room in the near future, it seems you do not have a optimal room/speaker combo - other than that, Rogue or ARC seem like good recommendations for use with Vandersteen - at least there seems to be a lot of folks happy with that pairing.

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.

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.
