Monolith 133304 Liquid Spark Headphone Amplifier by Alex Cavalli

The Monolith liquid spark, developed by Alex Cavalli for Monoprice, is a compact headphone amplifier that 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, offering plenty of power at 1300MW RMS into 50ohms (per channel), with very low distortion and switchable gain.

The design of the spark is a DC coupled topology from input to output, meaning it has no capacitors in the signal path to detract from the sound, resulting in an effortless and exceptional sound quality. The spark uses laser-matched, low-noise, audio JFETs for its differential input stage and high-performance, but very small MOSFETs for output power, leading to super-clean amplification and high power from a small footprint.

The spark additionally has preamp output RCAs, controlled by the volume pot, for use with powered speakers, making it an ideal configuration for an entry-level desktop setup that performs well above its price point. If you want to be where the music wants you to be, the liquid spark will effortlessly put you there at a very affordable price.

The THD+N (both channels) of the spark is impressive, with 1 Vrms (20mW) at 0.007% THD+N @ 1kHz, 5 Vrms (530mW) at 0.035% THD+N @ 1kHz, and 10 Vrms (2.12W) at 0.065% THD @ 1kHz.

Monoprice stands behind the Monolith liquid spark with a 1-year repair warranty and a 30-day money-back guarantee, so you can buy with confidence. This compact and powerful headphone amplifier is sure to deliver an exceptional listening experience, elevating your entry-level desktop setup to new heights.
