Chord Hugo 2 Transportable DAC and Headphone Amplifier
Hugo 2 is a powerful DAC and headphone amp that builds on the ground-breaking original.
Hugo 2 can be used both at home and on-the-go, either with headphones or within a conventional audio system. Its line-level output and full-function remote control adds real flexibility in full-size and desktop systems.
The device offers four 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 four-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 four 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 seven hours and two modes of automatic charging are included using the dedicated Micro USB charging port; an indicator shows charging and battery-charge status.

“The sound of the Hugo2 is undeniably divine in terms of how it manages to deliver a warm, human performance and yet doesn’t manage to lose any of the punchiness that digital music can excel at. Separating out things like kick drums, bass, rhythm guitar and almost anything with a beat is the Hugo2’s strong suit. It brings impeccable timing to the party and, the better the source, the better Hugo2 shapes the music.”
“Verdict: There isn’t another DAC around at anywhere near this sort of price able to communicate so torrentially, so unambiguously or so effortlessly. We like it a lot.”
What Hi-Fi, October 2018, 5 Stars and Best DAC over £1200, 2018
“On sound quality and utility – judging it as a complete package – Chord Electronics’ Hugo 2 is the finest DAC I’ve seen/heard/used to date.”
