Ray:
I had a pair of B&W Nautilus 805. A few recommendations I can think of would be top of the line amps from Creek and Musical Fidelity (can't remember the model numbers), but they would be about $1,500 new, and about $1,100 used. These British amps would likely be a good fit for the Nautilus line. Also, you could try a Bryston B60. I had great results with the Nautilus 805 by moving up from Arcam amp to Bryston 3bst & BP20 - the separates are likely too expensive for your budget but the integrated B60 will get you much of the way there. Good luck.
