What is the controller supposed to do ?

The Tube Stage will be making or braking the "super" part of the DAC, already a circuit in mind ?

good luck !

The controller has to communate between DAC chip and receiver,
also send the command to LED.

I think the tube stage will help to increase the sound quality...
What do you think....

In my mind...haha...actually already has a part of the circuit in my computer.

For balanced output you only need one PCM1794, two will only give you higher output current which is already really high.

I do not approve of commercial enterprises trying to outsource their research and development to DIY community.

Agreed. But if he offers low cost boards to the community and sells kits elsewhere I think it is less of an issue.

Solomon, would you sell bare boards at cost?
