properties

  • The Sundown Audio SALT amplifiers represent the pinnacle of Korean Class-D amplifier technology. They stand on the shoulders of three previous generations of Korean high-end amplifiers from 15 years (the SAZ v.1, SAZ v.2, and SCV series) to achieve even higher performance. Our customers have been asking us for many years to produce amplifiers that deliver optimal performance at realistic operating voltages in the 12-volt range and not at 14+ volts. The SALT - Sundown Audio Low-Voltage Technology - series is our answer!
  • "Whether you are a world-class SPL competitor, a dedicated enthusiast, or simply a fan of sound quality, the SALT series will feel at home in your system. Each individual model has been designed with great attention to detail to ensure that they bring a smile to your face every time the music starts playing, and that they will last for many years to come."
  • Cosmetically, they deviate significantly from our original design, which is an external indicator of the improved performance level. The heatsink is the heaviest we have ever produced, has the largest surface area, and is finished in a striking titanium color. These amplifiers look as good as they sound, and once you hold one in your hands, the build quality is obvious. The icing on the cake is the revised remote control with temperature, voltage, and clipping indicators, allowing you to easily monitor the vital signs of your valuable audio system.
