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.

Tough with incredible clarity
Used this little amp bridged through a 15" full range speaker in an emergency for the musical "Little Shop of Horrors". What we played through it were the piano, synthesizer and acoustic guitar from the orchestra pit. Clear, concise, and just "worked" doing it's job. When the "emergency" was over, we kept it instead changing back to the system we planned to use. After a few years of listening, it still reminds me of the warm clarity of the Macintosh Hifi amps of the late 50s and early 60s. Superb imaging. It sets a rather high standard for the other power amps I use.

Excellent performance and value
I'm using an SDS-224 for the mids and highs in a biamped system using magnepan speakers. This amp does a wonderful job on my ribbons and midrange panels. Everything jumps out of a totally black, dead quiet background. HIghs are sweet, fast and natural sounding with no edge or harshness. Mids are warm, full and have the bloom of a tube of amp but with better control and less distortion. Small, low level details come through so clear now with such a quiet background. I don't think you can beat the performance of Tom's amps at any price much less the deal he offers them at.
