HiFiMAN Prelude Class A Headphone Amplifier

Full Balanced Class A MOS-FET High Current Output
The fully discrete architecture features a precise, single-ended balance conversion circuit that renders the single-ended RCA input balanced.

Balanced Input Stage
The input stage employs a fully balanced amplifier architecture, with precise, single-ended/balanced conversion. The pre-amplifier circuit is independent, adopting a class A output structure, with excellent power and natural timbre.

ALPS Potentiometer
The potentiometer ensures complete and accurate channel balance.

High-power, low-noise
A customized high-power, low-noise torodial transformer, with multi-channel high-speed low-noise voltage regulator circuit, supplies power for the headphone amplifier.

Aluminium Chassis
The housing is manufactured from a single piece of aluminium, which helps isolate harmful resonance that negatively affects sonic output.
