Focal Arche Headphone Amplifier
Two separate amplifiers are built in which can be switched on the fly at the user’s discretion: Voltage (a pure current amplifier with lower impedance) and Hybrid (an integrated amplifier with higher impedance, featuring similar characteristics to a power amp).
Arche’s two balanced DAC chips can process formats in PCM format, 384kHz, as well as DSD 256 providing a versatile array of different playback options.
Designed to integrate seamlessly with the Focal high-end headphone range, Arche also features a dedicated profile for each Focal headphone model to ensure the best possible listening experience for users of Elegia, Stellia, Elear, Clear and Utopia.
