I too own a B&K reference 200.2 amp and Reference 5 S2 preamp. I just swapped out the preamp for tubes, as I wanted a little bit sweeter and smoother sound. I would rule out the Rotel. I have heard it in a setup and although it sounds pretty good, it lacks the bass extension and the dynamics of the B&K gear. The B&K gear is made in the USA, has a very solid build quality and never even gets warm even when I push it with 6 ohm speakers. I have changed everything in my system except for the amp if that tells you anything. I like it that much. The only thing I would consider above my amp is amps costing about $3500 and up. These would be the Mcintosh, Lass Labs, Krell and Mark Levinson
