Anyone have experience with Densen 200B+ ?

Basically I am in the market for a solid state preamp, and currently wondering between Ayre K5xeMP and Parasound JC2.  The entry level Densen intrigues me, it's affordable, good looking (that's important to me).  But there isn't much information available online for this unit.

I'm also wondering if anyone successfully paired Ayre preamps with McIntosh power amps? Because that's going to be my system, if I go the Ayre route.
