ASR Audio Systeme is a premium German audio manufacturer renowned for producing some of the most refined and powerful high-end amplifiers in the world. Founded by Friedrich Schäfer in 1980, ASR has earned a loyal following among audiophiles for its no-compromise engineering, exceptional build quality, and pursuit of sonic perfection.

At the core of ASR’s lineup is the iconic Emitter series, including the Emitter I and Emitter II amplifiers. These amplifiers are known for their modular architecture and separate, oversized power supplies. This unique design isolates sensitive audio circuitry from power-related noise, resulting in stunning clarity, detail, and musicality. The Emitter II Exclusive, their flagship model, delivers immense power with grace and precision, making it ideal for both delicate acoustic passages and demanding dynamic peaks.

ASR amplifiers are solid-state designs but are often praised for combining the warmth and richness of tube amps with the reliability and drive of modern transistor technology. Their sonic signature is transparent, natural, and emotionally engaging, making them a favorite among vinyl and digital audiophiles alike.

In addition to amplifiers, ASR also manufactures high-performance phono preamplifiers, such as the Basis Exclusive. These phono stages are often battery-powered to further eliminate noise and preserve signal integrity, offering an incredibly clean and lifelike analog experience.

Every ASR product is handcrafted in Germany with meticulous attention to detail. The brand emphasizes longevity and serviceability, with many units remaining in use for decades thanks to robust design and continued support.
