looks very nice!!!
good luck with the testing ...

Almost ready to start testing supplies and buffers.
Nice work!Control hardware is working well as far as I've been able to test. I've been battling with software for most of the afternoon. I'm having issues with device addresses. Linux-works/Bryan has been a great help figuring things out so far.
What about final cost?
I'm putting together a line stage to use with a 25K (I have resistors to rebuild it to 10K if that will work better) r2r attenuator, I already have a dcb1 buffer in the box, but I'm not sure if there's space for both buffer and linestage.
Do you recommend to run the line stage before or after the attenuator? Are there any use for the buffer when running the linestage?

Great! That was the answer I was hoping for I have another lcudino/d1 attenuator that I would like to put the buffer into.
I managed to populate the board ~50% with parts from my junkbox, the rest will arrive from mouser and digikey on tuesday or wednesday. Looking forward to try it.

That heat sink should be bigger. It runs class A for headphones. Some adjustments can be done to drop the current if you are just going to use it as a buffer. You can replace one of those diodes with the reversed silkscreen on each channel with a 100 ohm resistor to drop the current.
I guess i should find some way to lead the heat to the chassis, I have no ventilation inside the case so I guess I will be in trouble when I put the lid on even with lower bias.
Will it affect the performance if I mount the transistors on the baseplate next to the board and connect them with wire?
