Linear Tube Audio- Any feedback on their amps/ Preamp?

The Lawrence Audio speakers are an incredible match for the Linear Tube separates. See Terry London's review in Home Theater Review. He uses this combo.

Demoing the MicroZOTL 2 as a preamp and it is fantastic! I have had Audio Research Reference 5 and CJ Art 3. This gives up nothing to these far more expensive pieces! 

I did get the Linear power supply with remote and extra input. I have some great  6sn7 and 12at7 and they take this unit to completely different level. I listened with the stock tubes and couldn't imagine it being better but the unit is even more musical with the NOS tubes . I sit here listening to the demo unit feeling sad that I will need to give it back knowing it will be a couple weeks until mine is built. The shocker is that my wife even noticed. She is a professional musician and hears enough live music so that audio gear isn't important to her. She noticed how much more musical the system sounded with the preamp. She asked me if it was the preamp that caused the music to sound so much better. She asked why I had to give it back!

I use Beveridge model 2's. They are direct drive with their own OTL amps. Not all preamps play well with the amps and speakers. My two favorites are the CJ Art 3 and now the MicroZOTL. 

Lance, a friend who is a reviewer has that combination and it is quite good.
