Default anyone interested in Sorenson 3.0 amp layout?

I have designed a PCB for the Sorenson 3.0 amplfier. It's a cheap, stripped-down amp but might be fun to try out. Please comment on anything if you have any concerns. If there is interest, I would be more than happy to submit the design and have some boards made.

You can see the schematic at http://listen.to/audioexperiment and click on Archive at the top.

The schematic might be a little bit older than the layout, I can't remember. The board files are top+bottom with planes, top+bottom without planes

The real questions are; have you built it? and how does it sound?

The SorensonAmp has to be the most promising class D design I've seen for audio listening in that it doesn't use a clock generator.

Nope, not built yet. I am hoping to make a prototype on cheap PCB soon.
