Power amp suggestions for Usher BE 718

Help me out here..I have a small room and tend to prefer tube amps but am open to any suggestions..thanks...budget <2000 used.
CJ LP70s at 70wpc was the best (tube) amp that I have heard with Usher Be series. It was actualy better then dealer's prefered Nuforce Reference 9v2 SE amp.
However, it is only my opinion. Besides, price on used market might be way over your budget.
