The HiFiMAN Prelude is a fully balanced Class A headphone amplifier that represents the pinnacle of audio engineering. Designed with innovation, precision, and power, it delivers an unmatched listening experience and sets a new benchmark for headphone amplification.
At its core, the Prelude employs a fully balanced Class A MOS-FET high-current output stage, delivering exceptional dynamics and clarity. A precise single-ended to balanced conversion circuit transforms the RCA input into a true balanced output, ensuring faithful reproduction of every musical detail with lifelike realism. Its pre-amplifier circuit features a Class A output design that combines natural timbre with remarkable power.
For uncompromising accuracy, the Prelude integrates an Alps potentiometer, guaranteeing perfect channel balance and precision volume control—whether you’re listening to delicate acoustic passages or powerful rock tracks.
Power delivery is handled by a custom high-power, low-noise toroidal transformer paired with a multi-channel, high-speed voltage regulation circuit. This ensures stable, noise-free performance, while the balanced headphone protection circuitry keeps your headphones safe from distortion or surges.
The Prelude’s enclosure is milled from a single block of aluminum, not only giving it a refined aesthetic but also minimizing unwanted resonance for a cleaner, more transparent sound. Every component has been carefully selected and integrated to provide a pure, distortion-free, and emotionally engaging listening experience.
