So I was searching for some transformers and I stumbled across an Extreme 1543 DAC Kit from diyhifi.net. It looks like I purchased it in 2008 and also bought the upgrade to 8X 1543. I found the PCB populated and I don't think I ever finished the assembly. I can post some pics of it tomorrow. Here's the schematic of the PCB
Is there a way I can feed this an I2S signal?

It is for asynchronous reclocking, an idea popular at the turn of the century.
@MarcelvdG that had me laughing. It sounds so funny to say.
I realized after I read the data sheet that they accept I2S. It looks like I can just connect an Amanero or similar to the corresponding pins of the CS8412. Then cut the last power supply section.
It should make music after that correct?

You will need to keep the CS8412 from excessively loading the I2S source. Cutting the CS8412 supply probably doesn't do the trick, because CMOS ICs usually have diodes from all signal pins to the supply (and ground).
By turning on the section of SW4 that pulls up the M0 pin, you can put the CS8412 in its mode 3. Its word clock and bit clock lines then become inputs, so only the data output needs to be physically disconnected from the TDA1543s (pin lifted, trace scratched, whatever).
The TDA1543 digital inputs are supposed to be TTL compatible, meaning that anything below 0.8 V counts as a low level and anything from 2 V as a high level. Driving them from 3.3 V or 2.5 V CMOS levels should therefore work fine.

Excellent... I'm thinking of just de-soldering the chip. There's still some legit sources on ebay just in case I want to go back.
I could just solder one of these back in an tap in that way
