I am currently using Levinson 334 amp driven by Levinson 390s Cd/Preamp with Watt/Puppy 6's, but I had the 5.1's before. Both combinations sounded great to me. I tried a BAT VK-75 tube amp and found the general flavor of the sound to be the same but less dynamic so I didn't keep it in. I tried the Rowland Model 12's and while there were several aspects to the sound that I liked there was a harsh glare--perhaps attributable to the Rowland's extended high end bringing out problems with the Wilson speakers' tweeters--that I couldn't live with.
