Yep, apologies - been very busy with life lately. So my partners decided to design a version of the board with a much higher percentage of SMD components. Reason is, just the design articles we had to stuff each time convinced them that there was no way they'd be able to produce even a moderate number of boards on order. It's a very small team after all.
This past week was dedicated to final listening tests to insure that performance did not in any way suffer. are was taken to spec same or better SMD parts, and parts that were much more expensive in SMD were left unconverted. Anyway, short story - new board layout sounds great and measures very well.
Board / parts should be ordered very soon, and information for the Gb should be posted very very soon.
