Description

In 2014, Chord Electronics introduced Hugo, a revolutionary portable DAC and headphone amp that became a landmark product in the audio landscape. Advances in digital technology, including the latest FPGAs and WTA (Watts Transient Aligned) filters, have enabled Chord to introduce a next-generation version, Hugo 2, featuring flexible new features, plus next-generation technical and sonic performance. 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.

Hugo II 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.

Sleek new aircraft-grade aluminium casework
New levels of technical performance
Four digital inputs
User-selectable filtering option
Crossfeed feature
Battery life improved
Lower distortion, better output stage

Sleek new aircraft-grade aluminium casework

Featuring a newly designed precision-machined aircraft-grade aluminium case, Hugo 2 is distinct from its predecessor with its sharper, lower profile design and four spherical control buttons. The spheres, which are top-mounted to allow for possible future expansion side-modules, illuminate with colour-coding information and control power, input, filtering and crossfeed functions. The top-mounted volume-control sphere has been retained and made larger for more intuitive operation.The stylish new design and additional functionality has been introduced in anticipation of greater indoor use within both desktop and conventional home audio systems, despite Hugo 2’s obvious portability. The inclusion of a full-function remote control adds further flexibility and the practical line-level output mode of the original has also been retained.

New levels of technical performance

The latest FPGA and advanced WTA (Watts Transient Aligned) filters have been implemented in the Hugo 2, bringing a wide variety of performance improvements in a number of areas. Performance gains have been made in timing accuracy, noise reduction, headphone amp power and dynamic range.

Four digital inputsHugo 2’s connections and switches now feature laser-ablated function-lettering for improved ease-of-use. 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.

User-selectable filtering option

A four-function switch filter, operated by its own control sphere, offers a useful degree of user-selectable frequency-shaping, bringing warm and soft or transparent and incisive presentations, giving additional flexibility and user control.

Crossfeed feature

For headphone-listening, Hugo 2 retains the popular digital crossfeed function of the original and offers three operation modes from its dedicated control sphere. The system cross-feeds a partial 400 millisecond-delayed and shaped signal from each left and right output to the opposite channel. The system duplicates the effect of listening to speakers and is based on advanced binaural audio research.

Battery life improved

Battery playing time is around seven hours and two modes of automatic charging are now included using the dedicated Micro USB charging port: fast (1.8 amperes) and slow (less than one ampere). An indicator shows charging and battery-charge status.

Lower distortion, better output stage

New digital DC servos have replaced the inline capacitors in the original output stages and reduce distortion further while improving the power-drive performance and capability of the output stage. An element of switch-on delay has resulted, but the performance benefits were felt to outweigh the disadvantage.
