Anyone famaliar with the manufacturer,and in particular

impressive.The advertised 10 day audition is appealing.

Sherod,

I have a rudimentary users manual when my unit was a 2.0 but no schematic in that info. Another omission in the early manuals is the fact that the preamp inverts polarity. Make sure all who use this preamp switch positive and negative speaker cables EITHER at the amp end or speaker end (not both) to get the correct phasing.
Sherod and Scifi,

I have contacted Joseph Chow about the tubed power supply grade. I will report back here -- hoping to have a positive outcome soon.
