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.
