Focal Arche DAC and Headphone Amplifier


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 up to 384kHz, as well as DSD 264. 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.

Dual-mono design maximizes stereo separation

All DACs are only as good as their, well, DAC chip. Focal chose one of the best out there for the Arche: the high-grade VERITA AK4490 DAC chip. These are stereo DAC chips, so Focal could've used one and called it a day. But by using two in a dual-mono configuration, Focal was able to reduce noise and crosstalk compared to using a single chip.

In fact, the Arche uses dual-mono balanced circuitry throughout. There are dedicated Class A amplifiers for both the left and right channel for potent sound with well-defined stereo imaging. 


The ins and outs

Focal designed the Arche to get the best from all your music sources. The back-panel offers digital and analog inputs, including optical and coaxial digital, and even a USB Type B input. That means you can connect everything from disc players, streaming audio devices, a computer, and more. 

On the front panel, you'll find a 1/4" unbalanced output and a balanced 4-pin XLR output for headphone listening. On the back, there are unbalanced stereo RCA outputs and balanced stereo XLR outputs. So you can use the Arche as a standalone preamp or DAC with compatible gear.
