Focal Arche DAC Amplifier Update

Focal Arche - front

Latest Update Available Now

Last week Focal released a new update for the Focal Arche Amplifier, featuring a number of optimizations to the unit. The update process is manual rather than automatic, but we'll walk you step-by-step through the process. You can find the instructions below.

Main Features

  • Digital-analog converter compatible with high-resolution formats (384kHz - DSD 264).
  • 2 integrated amplifiers (voltage and hybrid): choose the amplifier type best suited to your headphones.
  • Presets for every set of Focal headphones: get the best from Focal’s combination of electronics and acoustics.
  • Dual mono audiophile construction from input of the digital signal to output of the self-powered signal.
  • Can also be used as a digital-analog converter for high-fidelity home systems


Arche is an all-in-one solution, offering presets for every set of Focal High-Fidelity headphones (Utopia, Stellia, Clear, Elegia and Elear) to make sure you get the absolute best from this ultimate combination. Owners of Focal headphones can be sure they are enjoying a combination of electronics and acoustics that is carefully thought out and specially developed from the very outset. Arche will be updated by using a USB stick.

The two premium AK4490 balanced digital-analog converters can process formats in PCM format up to 384kHz, as well as DSD 256. The analog signal is then routed towards 2 pure class A amplification modes designed especially for headphones (voltage, hybrid) for an uncompromising solution. The original audio signal is totally respected, so as to reproduce the tiniest details of the recording.


Upon entry of the digital signal, Arche offers a resolute audiophile design through its uncompromising dual mono construction, from signal processing to amplification. And thanks to the presets integrated, every user of Focal headphones gets amplification to suit their product and their favorite tonal balance.


Arche comes with a solid aluminum headphones mount inspired by the brand’s logo: accessing and storing the headphones is therefore quick and easy, as well as looking incredible and saving on space!
