Id recomend beefing up the ground track, or better still try and flood the ground copper.

Interesting little chip and design, I'd be interested in doining a full SMD layout just to see how small it could be made.

Let me know when you have a prototype that you want tested. I have 2 PCM2704 chips already and we can work out a BOM. It will be my first time soldering SMD, but it shouldn't be too tough.

I use Cadstar so I'll copy the schematic into cadstar and have a play.
