The LDA ultra low distortion audio power amplifiers home

The Euraudio LDA ultra low distortion power amplifier family consists of five high performance audio power amplifier DiY kits, which are recommended for experienced hobbyists interested in high-end audio. Each kit contains the LDA17 ultra low distortion power amplifier board with medium, high, or extra high power component set and other necessary circuitry like power supply, protection circuits (not all kits), and relay. There are stereo, dual mono, and mono kits available.
