Belles Research

A US based manufacturer of high quality audio amplification, Belles Research Corporation was founded by David Belles who is now designing and manufacturing amplifiers under the Power Modules brand name.

Belles Research

At Belles, each preamplifier is carefully built by hand to make sure that all components fit and are not abused, unlike products that are fabricated by automated methods. We use only top grade discrete components in all circuits. All transistors and switches reflect Belles' concern for the human engineering aspects of his products. Each unit is carefully assembled and final tested by dedicated skilled technicians. Belles products are hand crafted to ensure quality, reliability and performance. Belles products offer an edge over mass produced audio components.
