LM3886 amplifier boards (pair)
The HiFiOcean LM3886 amplifier board is a minimalistic, hi-fidelity implementation of an audio power amplifier based on the venerable LM3886 chip. It is unusual in using the differential configuration for the LM3886 (not the non-inverting one commonly used). The chosen circuit topology and special routing of the PCB traces add up to deliver great audio performance.
The board is designed to have measurably and audibly lower distortion but the same size, general layout, and mounting pattern as the boards previously offered by ChipAmp.com. The board uses only a few easy-to-solder through-hole parts.
