Chord Hugo 2 Mobile DAC/Headphone Amplifier

Introducing the next generation of the award-winning Hugo portable DAC and headphone amp. The Hugo 2 is a powerful DAC and headphone amp that builds on the ground-breaking original. Designed for both home and mobile use, Hugo 2 transforms headphones and audio systems’ sound quality with cutting-edge proprietary DAC technology.

The device offers 4 digital inputs (optical, coaxial and HD USB) plus extended-range Bluetooth, with high-resolution file playback up to 768kHz and up to DSD512 (Octa DSD), via its HD USB input. Analogue outputs include 2x RCA, plus 3.5mm and 6.35mm headphone outputs.

A 4-function switch filter offers a useful degree of user-selectable frequency-shaping, bringing warm and soft or transparent and incisive presentations, giving additional flexibility and user control. For headphone-listening, Hugo 2 retains the popular digital crossfeed function of the original and offers three operation modes. The system duplicates the effect of listening to speakers and is based on advanced binaural audio research.

Hugo 2 features 4 spherical control buttons, which illuminate with colour-coding information and control power, input, filtering, plus the unit’s crossfeed functions.

Battery playing time is around 7 hours and two modes of automatic charging are included using the dedicated Micro USB charging port; an indicator shows charging and battery-charge status.
