From the project

A USB Based HiFi DAC AMP Made by Dan Abidov and Luke Stirzinger

The goal of this project is to demonstrate that both high resolution and high sampling rates can be achieved in a compact, affordable system. While a moderate amount of theoretical information explaining how a DAC-amplifier system functions is available online, practical guidance regarding component selection, layout considerations, IC integration, and signal-path design remains limited. This project therefore also aims to serve as a technical resource for future designers interested in high-fidelity audio systems, reducing the barrier to entry and simplifying the development process.
