I was previously using a GeekWorm X400 V3.0. My setup is simply an rPi4 + ProtoDAC at this point. I think my next steps are 1) look at a Pi Zero WH implementation, 2) a re-clocker, 3) better power supply.
Much thanks to @hifinet, @Tim Curtis, and the many contributors on this forum. I spent far more time lurking and researching than it took to build.
[My build experience]
I have no experience with component soldering, so I spent a few weeks with practice kits and got the feel for it. After assembly, I immediately knew I had something wrong. I got a ton of feedback/static and barely any sound. I figured I had a cold solder joint somewhere. I spent hours re-checking and re-flowing various connections to no avail. I had a few beers and went to bed. The next morning I re-read the build instructions and voila. When connecting the module, I forgot the module diagram was top-view and I had inverted some of the pins soldered (I purposely had soldered more pins for structural strength, but not all). I am probably lucky nothing fried since I didn't have GND soldered (although I was testing with cheap desktop active speakers). Note: the installation of the C3,C4 electrolytic capacitors is missing from the assembly instructions. No biggie as it's obvious.
This is so much fun, I can't wait to do more!
Re "Note: the installation of the C3,C4 electrolytic capacitors is missing from the assembly instructions."
Indeed there is no assy instruction for them.
@hifinet, when u get a moment send me a step for C3/C4 install and and I'll. update the doc.
