Hi,
Thank for sharing great project.
I had a question about the rp2040 DAC and amplifier. Is it possible to use other headphone amplifiers in the market instead of the kit's original driver? How much decrease in quality will i get?
i mean a driver like this one which i've found by google:

The original pico PCB is somehow hard to solder for an electronic noob like me (because of the small parts, and accessories which i do not have).

Cheers
