Thanks to John Brown from ECdesigns for sharing his work.

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.
Using Iancanada I2S to PCM PCB
DIY I2S to SIM PCB
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.

Brilliant!! Moving to Laos in 5-6 weeks - who knows what the postage service is like there! Should get to me here before then. Maybe a while before I get the BOM together 🙂
Does this support 24 bit data? I also need inverted data for a balanced DAC. Will two boards and swapping some components work for balanced?
Wish I had the knowledge to help you.
The best person to ask would be ECdesigns.
I've only tested this PCB running at 16/44.1k
Hi all,
First batch of PCBs have been sold already.
Im expecting the next batch soon.
If you want to reserve a PCB go ahead and fill out an order form and ill send an invoice for a deposit.

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.
New PCBs shipment
Hi All,
I received a new shipment of PCBs.
All but 2 are accounted for.
I have more coming next week.
All orders paid for will be shipped out this week.

I was just wondering when people would start getting their PCBs. Let us know how you go.
