Sundown Audio SALT-3

The SALT-3 from Sundown Audio sets new standards in 1-channel amplifiers. As the pinnacle of Korean Class-D amplifier technology, it will impress you with its optimal performance at everyday voltages. Whether you're an SPL competitor, a hi-fi enthusiast or a lover of sound quality, the SALT-3 series has been designed with great attention to detail to put a smile on your face every time the music starts playing. With a powerful MOS-FET PWM power supply, a stable 1-ohm load and a variety of filter options, this amplifier range offers innovative features that ensure an excellent listening experience.

• The Sundown Audio SALT amplifiers represent the pinnacle of Korean Class-D amplifier technology. They stand on the shoulders of the three previous generations of Korean high-end amplifiers from 15 years ago (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 12s range rather than 14+ volts. The SALT - Sundown Audio Low-Voltage Technology - series is our answer!
• Whether you're a world-class SPL competitor, a dedicated enthusiast, or just a fan of sound quality, the SALT range will feel right at home in your system. Each and every model has been designed with great attention to detail to ensure they'll put a smile on your face every time the music starts playing, and that they'll last for many years to come too.
• Cosmetically they are a big departure from our original design, which is an outward indicator of the improved performance level. The heatsink is the heaviest we have ever made, has the most 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 redesigned remote control with temperature, voltage and clipping indicators, allowing you to easily monitor the vitals of your precious audio system.
