The Jeff Rowland Model 12 is definitely the way to go with the B&W N802s. Likewise I thought the Model 12s were one of the finest amplifier I had audition, althought at that time I couldn't afford them. The levinson is a little on the dark side, slow and sluggish with the B&W. The Rowland is exactly the opposite, it's fast and clear, not to mention a little sweet. The close amplifier I can think of that similiar to the Rowland Model 12 is the Spectral DMA-360.
