The new Chord Electronics Hugo 2 Portable Headphone Amp and DAC is designed to be used at home or on-the-go, either with headphones and with 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 two RCA, plus 3.5mm and 6.35mm headphone outputs.
The four-function switch filter offers a useful degree of user-selectable frequency-shaping, delivering warm and soft or transparent and incisive presentations, bringing additional flexibility and user control. For headphone-listening, the Chord Electronics Hugo 2 Portable Headphone Amp and DAC retains the popular digital crossfeed function and offers three operation modes. The system duplicates the effect of listening to speakers and is based on advanced binaural audio research.
The Chord Electronics Hugo 2 Portable Headphone Amp and DAC features four control buttons, which illuminate with colour-coding information and control power, input selection, filtering options, plus the unit’s crossfeed functions.
Battery playing time is approximately 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.
