Furman

Furman is a U.S. pro-audio brand founded in 1974 by Jim Furman, with roots in the live-sound and Grateful Dead-era touring scene in Northern California. Its heritage is not in consumer hi-fi components, but in solving the practical problem of clean, reliable AC power for demanding audio systems.

The brand is best known for power conditioners, voltage regulators, surge protection, and related power-management products for studios, broadcast, live sound, and home theater. Furman’s name is most closely associated with rack-mounted AC filtration and protection rather than amplifiers, speakers, turntables, DACs, headphones, or cables.

In the market, Furman sits in a specialist, professional-focused niche rather than the high-end audiophile mainstream. It has a long-standing reputation for utility, reliability, and system protection, making it a familiar choice for working engineers and serious home-theater users who want robust power infrastructure more than flashy audio hardware.
