What do you think of this preamp design?


I've been on the hunt for a preamp and came across the Audio-gd C3 final version:

It comes with schematic of the signal section. Does it seem to be well executed? Any obvious or subtle design flaws? It has had some positive reviews by owners on the web.

Ralph, I saw that opamp in the feedback loop was puzzled because they claim they don't use any chip based opamps in their amps.
BTW, I heard you're working on remote volume control for the MP3. When will it be ready? Did you see my thread on this forum about lack of a remote control being a deal breaker for preamps? More than I thought need remote.
We are trying to have it ready for RMAF... at any rate, like the MP-1, the remote for the MP-3 will be retrofit to any earlier MP-3.
Looks a bit like PS Audio's gain cells but more complex and less "empty" box.
