Record Player USA Founder

James Concorso, has been refurbishing portable record players since 1970, and has been an electrical engineer since 1983. James obtained his first patent in 1994 for a high-end MOSFET audio amplifier design.

Fascinated with enthusiast opposition to negative feedback, James invented something called “Premonition,” which eliminated those traits of negative feedback found to be most objectionable. Premonition earned James his second patent in 1999, a document containing eighty-three algebraic equations, all created by James without a computer. The equations defined an optimal feedback network design that eliminated ringing, overshoot, and transient intermodulation distortion.

Curious as to whether his results were ideal, James enlisted the help of his friend Bill Whitlock, whose company, Jensen Transformers, sold network analysis software called “Comtran.” Bill inputted James’ component vales into Comtran, and, much to his surprise, found that James’ equations were not only ideal; they reached a higher degree of optimization than Comtran.

Bill, who now sits on the standards committee of the Audio Engineering Society, became James’ first witness to Premonition when he visited New Jersey. Years later, James would become coinventor of Bill’s Balanced RCA Connector System, which earned a patent in 2012.

James invented a new kind of audio compression in 2005 called “Elevator.” At moderate levels of gain, Elevator produced a louder signal with absolutely no artifacts commonly associated with audio compressors.
