Description
Hifiman Prelude Fully Balanced Headphone Amplifier
PRELUDE Fully Balanced 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 fully balanced.
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.
A customized high-power, low-noise toroidal transformer, with multi-channel high-speed low-noise voltage regulator circuit, supplies power for the headphone amplifier.
Fully balanced headphone protection circuit
The housing is manufactured from a single piece of aluminum, which helps isolate harmful resonance that negatively affects sonic output.
