Thanks to John Brown from ECdesigns for sharing his work.

This PCB is based on schematics posted here.

Comparison mp3s - I recorded the same song twice, once using my old setup, and then with the new PCB installed. Headphones will make it easier to hear the difference.

The V2 PCB is now avaliable.

This version has inverted data outputs to enable balanced operation - can run up to 4 x D3 PCBs in dual balanced operation, and 2 x D3 PCBs in dual mono/parallel operation.

Excellent project thanks. I wonder what differences you hear direct in your system?

Hi kazap,

Sterreo image has changed. Sources of sound in the soundstage have become more pronounced to their position, bringing with it a more realistic musical representation. Symbols have more sparkle, vocals bring with them more of a feel for the space they are in and bass has more authority.

The differences are subtle, but they are definitely there. YMMV.
