Best tube amp for Wilson Watt/Puppy

The CAT tube amps have tremendous synergy with Wilson speakers. In fact, the guys at Innovative in Manhattan said that the CAT monoblocks paired with X-1's yielded the best sound they have ever gotten out of a two-channel system. That said, and while they are unusually well built, those amps can be quite finnicky, and expensive, to own - they require very carefully vetted output tubes, which CAT charges outrageous prices for, for reliable operation due to the hot-rodded circuit. Both the monoblock and stereo versions of the amp can found for less than $10,000 used. I believe a new stereo amp (the JL-2) goes for +/- $14,000 new.

I think Wilson is voiced and optimized for Audio Research.

I would think about 2.Hand CAT amps

I owned Watt/Puppy VI and the best tube amp for these speakers is Spectron Musician III SE, well under $10k even with upgrades. My friend owns Watt/Puppy VII w/Spectron and sound, overall, is the BEST.
The second choice is used Audio Matiere tube amp - if you can find it.

I agree you would be hard pressed to do better than a CAT JL2.
