Focal Arche





Manufactured in France, Arche is a unique electronic solution which combines a digital-analog converter as well as two pure class A amplification modesdesigned especially for headphones. Ideal to sit between the digital sources and your audiophile headphones, Arche is the perfect solution to fully enjoy your headphones, whilst benefiting from the performance delivered by the converter to drive high-fidelity loudspeakers!

So Arche is an all-in-one solution, which also offers presets for every set of Focal High-Fidelity headphones (UtopiaStelliaClearElegia et Elear) to make sure you get the absolute best from this ultimate combination: owners of Focal headphones can therefore 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.
