Product Overview & Specifications
Full Balanced Class A Headphone Amplifier
With MOS-FET high current output, PRELUDEs 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.
Clean Power
A customised high-power, low-noise toroidal transformer, with multi-channel high-speed low-noise voltage regulator circuit, supplies power for the headphone amplifier and a fully balanced headphone protection circuit.
Aluminum Chassis
The housing is manufactured from a single piece of aluminium which helps isolate harmful resonance that negatively affects sonic output.
