High-end audiophile amplifier and DAC

Focal has established itself as a key player in the high-end headphones market. The brand completes its high-fidelity Headphone Collection with Arche, an electronic associated solution to amplify your songs and your emotions. Thanks to the digital-analog converter and the pure class A amplification modes designed especially for headphones it integrates, Arche ensures an exceptional sound quality throughout your listening session.

Arche is a unique audiophile solution. It combines a digital-analog converter with two pure class A amplification modes (voltage, hybrid), designed especially for headphones. Arche also offers presets for every set of Focal headphones to make sure you get the absolute best from this ultimate combination. Its dual mono ultra-high performance construction makes it possible to separate management of the left and right channels, from the powering stage. The two balanced digital-analog converters can process formats in PCM format, 384kHz, as well as DSD 256. The analog signal is then routed towards 2 pure class A amplification channels for an uncompromising solution. The original audio signal is thereby totally respected, so as to reproduce the tiniest details of the recording.
