Description

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.

Who says that a chip amp can't deliver tube quality PLUS!
Thanks for building this SDS 460 for me! On Thursday of last week I wired up the amp and plugged in my 2 x18 Cab, then my foot pedal and P-Bass. All I can say is WOOOW!!! My P-Bass and Cab came to life in a way that has never ever sounded so full and rich with solid bottom end and string harmonics that blew away my Fender 100 Watt tube amp. It was night and day. The amp is dead quiet! No 60 Hz Hum! I couldn't wait to play a gig on Friday night. The lead guitarist plugged into channel 2 with his foot peddle, and 4x12 Cab. I was on channel 1. The look on his face was priceless. We lit up a 6000 square foot Venue at half volume, the people in the back, standing room only were in awe!! The lead guitarist did a solo that was incredible! Tube amps have nothing on this amp. The octave lower and higher gain made our equipment come to life. It's not at all bright. Who says that a class D amp can't deliver tube quality PLUS!
Thanks for all your help and patients, "YOU ARE THE MAN!!

Great power and sound at a great price
I'm using an SDS-258 on the bass panels in a biamped setup and am quite pleased with the performance of this amp. It has great power into a 4 ohm load, is dead quiet yet dynamic and grips my bass panels with authority. The bass is taut, fast but with the warm, natural sound and bloom of a tube amp but wihout any overhang or fat. This amp gets the timbre of acoustic instruments just right--you hear the wood and body of a string bass, the bite of a bow on the strings of a violin and the attack, bloom and decay of the bass notes on a Steinway. Simply outstanding performance for an amp at this price.
