If you’d use 1970’s sized components, I’d stand a chance

Nice work

My Prototypes are almost all thru hole parts.

Hi Judydudi,

Thank you for getting back to me.
I’m currently building a small batch of new design , version V2.4, with individual switch on each bit , and it has much lower internal resistance .
For sound quality, it has more decent bass and more detail . The PCB is a little bit larger than previous one.
Here’s the photo of the DAC. Sorry for the low quality camera at low light.
