This is probably not the advice you want to hear, but if you have 2K to invest I would move out the Vandersteens which are unsuitable for a room this small rather than invest the money on an amp specific for them. They are classic speakers but need a big room.
tube integrated for Vandersteen 2's
I've been looking at the Rogue Cronus Magnum and the Cary SLI-80 for the Vandersteens. In a small room 8 x 10 with mostly jazz. any other ones in the $2K price point to consider?
