USB audio sound card (PCM2702)

Very nice!

If you could produce a super-simple PGA2311-based preamp kit with a simple serial input, I would be very interested.

Also, I know that Jan at 41hz.com is very interested in producing a PGA3211 preamp. He'd probbably be willing to pay a bit of money for rights to your design.

Just curious, though - why not use a TDA1543 or similar DAC with a PCM2706's I2S output? I've heard it's of much better quality than the PCM27xx line.

The HPDAC looks awesome. I just can't afford one right now, and I'd really prefer to buy a kit over seperate parts.

I've got the boards and some of the parts for the HPDAC, and can't wait to finish it up.. It would never hurt to have another TDA1543-based DAC, though (I have like 12-16 of the chips laying around).

This is my PGA2310/PGA2310 preamplifier:



well, not quite a preamplifier but volume control

HPDAC looks really nice.
