The Esparagus Audio Brick is an open-source, ESP32-powered hi-fi DAC/amp designed for tinkerers and smart home builders. Single brick delivers two channels of clean audio using the TAS5825M DAC with built-in amp; Ethernet and Wi-Fi onboard, and can be stacked for multi-room or multi-zone setups. Out of the box, it integrates with Home Assistant via ESPHome, supports Music Assistant as a native media player, offers Snapcast for near-perfect sync, and includes LMS protocol support for Spotify Connect, AirPlay, and more with squeezelite-esp32. With full DSP access (15-band EQ, gain, fault management) and OTA updates, it's both a hackable dev board and a ready-to-deploy smart audio endpoint. It is designed to be mounted on the DIN-rail and adds extra heat management for working in harsh environments. The Esparagus Audio Brick delivers up to 30W per channel in a stereo setup, or up to 65W in mono; however, it can also be used in bi-amp config, serving highs and lows separately.
