Hi,
I’d like to share my DIY sound card project.
It’s a high-quality design based on PCM1792 DAC, SRC4193 resampler and TPA6120 headphone amp, with USB and optical inputs.
I also did some measurements to evaluate how different components affect the output noise.
The project focuses on clean signal path and reducing noise (including USB isolation).
