EASTER SALE! GaN Amps - Going On Now Through 04/02/2024

SDS-120 Class D Audio Kit with Large Power Supply, AnTek 300VA Transformer, Molex Connectors for external LED’s, power switch, and gain controls. High Quality Conductive Plastic Element External Gain Controls also included. Our new Super D Series audio power amplifiers are built on the highly acclaimed reputation of our CDA series amps. Our goal was to keep the excellent sonic qualities while adding a state-of -the art balanced input stage (also accepts standard single ended input) and external adjustable gain controls. We’ve also added a better cooling system, Molex connectors for external LED’s, power switch, and gain controls (included). The balanced input stage is one of the finest available and normally only found on very expensive high-end equipment. When using single ended inputs, you can change a jumper to select inverted or non-inverted input as well… useful in some instances. The gain controls included with this kit feature a conductive plastic element for ultra low noise. Our Super D Series amps provide more life-like imaging and sound stage, along with the beautiful smooth tube-like sound we’re known for. These amps are powerful, clean, quiet , and transparent.

    I bought the SDS-120 kit. I used an Korg Nutube B1 Preamplifier module as a preamp. Installed all in a rack mount chassis with only a on/off switch and a volume control. Built new Jordan VTL speakers using Eikona 2 drivers and a 15″ subwoofer. It sounds complete unreal. Such dynamics and detail. This is hard to say but even better that my Mission Cyrus One. Runs very cool and never had one hiccup with it in two years. Very, very happy. Highly recommended as the value with this setup is incredible.
