what solid state amps for the soundlab u-1

The Innersound ESL-300 works fine with U2's so, I would assume it would work equally well with the U-1's. This is one generation removed and I have not heard the current genertion Innersound amps but, one can only assume they would work equally well, or better. The Parasound JC-1's also are reported to work well with Soundlabs.

Yet when it comes to Soundlabs, in my opinion the Atmasphere amps (especially the MA-1 and 2) reign supreme. You must try one of these when you set up a dedicated listening room.

i was not aware that there was a u-2 the website only lists the u1.

I remember a few years ago when I worked for a Soundlab dealer we were running the Fourier OTL amps with the A1s. I brought my old Krell KSA 250 over and everyone was surprised at how well the Krell did with the Soundlabs especially since they were such a high impedence. Since then the owner of the store has switched over to Krell for his own amp.

Among the amps I'd recommend with your U-1's include models from Parasound (JC-1), Pass Labs, Levinson, Accuphase, Jeff Rowland, Clayton Audio, and Warner Imaging. I'm sure there are others, but I'm limiting my comments here to my own experiences. Disclaimer - I peddle some of these lines (as well as Sound Labs).

If wall juice is indeed a limiting factor, you might want to consider the Model 501's from Jeff Rowland.
