Circuit design and board info available here:

Look at the info in the thread to see the PSU requirements.
Basically you need +/-5V for digital and +/-5V for analog sections.
The IV op amps shares the +/-5v with the PCM63's analog section.
However, I have chosen to wire the op amp to have their own +/-12V supplies (simply by leaving 4 jumpers on the board empty).
This, to me is essential for the IV to produce better sound quality.
Board fully populated with good quality caps eg. Elna Tonerex with Vishay MKP for the op amps, Nichicon KG with Panasonic smd film for the analog supplies, Unicon polymer caps with Panasonic smd film for the digital supplies, and Samsung ceramic bypasses for the glue logic chips. IV resistor is the milspec Dale 'blue devils', which sounds much better than the Dale brown ones. Parts have been chosen based on my personal experiences with a few boards done to get the best out of this DAC. Lots of parts purchased, stored, listening, my energy and time etc....🤣
uf.l connectors have been installed on the i2s inputs, in case you want to use uf.l cables to connect to your i2s source.
The complete DAC board + shipping worldwide ( registered + tracking) = US$275
As usual i will treat Miro to some coffee.
Paypal FF only please.
