It uses dual 18V filtered power supply rails to produce wide voltage swings for additional headroom. The Liquid Spark offers plenty of power at 1300mW RMS into a 50 ohm load, with very low distortion and switchable gain.  .gte-ctr .row{margin:0;}3 Year Replacement WarrantyMonoprice™ not only stands behind this product with a 3 year replacement warranty, we offer a 45 day money back guarantee as well!
