Has anyone ever heard the Audio Research LS-10 pre

I've only seen one review for this preamp and Audioreview.com and nowhere else. Can anyone give me some feedback on this solid state preamp?
I own the ls -10 and find it to be a very nice pre. This is not a very pop pre becouse it is ss and comes from Arc known for thier tube gear .Anyway FI did a nice review which you have probably come across .I am currently using mine with 2 Bat vk 60's.
Audio Research currently has an LS-12 solid state preamp currently on the market...any idea how it compares to the LS-10?
