Bongiorno designed amplifiers in six different decades, working alongside other industry legends such as Richard Sequerra, Sidney Smith, David Hafler, Morris Kessler, John Curl, and Bascom King. Bongiorno will best be remembered for Great American Sound (GAS), the company he founded in 1974 after leaving SAE. The GAS Ampzilla power amplifier was an instant classic, outperforming many much more expensive amplifiers and sending ripples through the industry. Bongiorno was eventually forced out and the company folded a few years later. He quickly founded a new company, Sumo Electric Company, Ltd., to bring his circuits to moderately priced products. As with GAS, disputes between business partners led to Sumo’s premature demise. Everything about Electra's design underlines Sumo engineering's fanatic attention to detail. While other preamps give you volume controls, Electra provides laser-trimmed stepped attenuators for volume, bass treble and balance. These controls will pass high frequency square waves with no apparent distortion, and offer near-perfect channel to channel tracking. 1% metal film resistors are used throughout the signal path. The phono preamp stage for moving coil cartridges is both fully complementary and DC coupled, as is the FET magnetic phono stage. The entire preamplifier remains in phase from input to output. Even the circuit topology has been configured to reject stray magnetic fields, which can introduce hum and noise into the system. When Electra is used with other Sumo equipment, such as the Andromeda, the interaction is synergistic. The whole is greater than the parts. You will hear a wide, accurate soundstage, incredible dynamic range, astounding definition throughout the audio band. In short, the natural, effortless purity of live music.
