The Monolith Liquid Spark is a compact headphone amplifier developed by Alex Cavalli for Monoprice. It provides everything people have come to expect from a Cavalli design. It uses dual 18 V filtered power supply rails to produce wide voltage swings for additional headroom. The Spark offers plenty of power at 1300mW RMS into 50ohms (per channel), with very low distortion, and switchable gain.
