Sleek new aircraft-grade aluminium casework
The CHORD Hugo 2 features 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 are top-mounted to allow for possible future expansion side- modules. They 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. It suits both desktop and conventional home audio systems, despite Hugo 2’s obvious portability. The inclusion of a full-function remote control adds further flexibility. 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. It brings 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 inputs
Hugo 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. Up toDSD512 (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.
For headphone-listening, Hugo 2 retains the popular digital crossfeed function of the original. It 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.
