Developed by Rob Watts as the ultimate "portable" headphone amplifier, it is of a quality that can easily compete with most stationary units: Hugo 2.
Portable reference DAC & headphone amplifier with FPGA, WTA filtering and Bluetooth®
In 2014, Chord launched the original Hugo — a revolutionary portable DAC and headphone amplifier that quickly became a milestone in the audio world. Advances in digital technology, including the latest FPGAs and WTA (Watts Transient Aligned) filtering, made it possible to introduce a next-generation version: Hugo 2, offering flexible new features as well as next-level technical and sonic performance.
Winner of “Best DAC (£1,500+)” at the What Hi-Fi? Awards 2022, and a What Hi-Fi? Best DAC winner every year since release (2017–2022), Hugo 2 is a proven class leader.
Hugo 2 can be used both at home and on the go, either with headphones or as part of a conventional audio system. Its line-level output and fully functional remote control bring real flexibility to full-size and desktop systems.
The unit provides four digital inputs (optical, coaxial and HD-USB) plus advanced Bluetooth® wireless technology. Via its HD-USB input, Hugo 2 supports high-resolution playback up to 768 kHz and up to DSD512 (Octa-DSD). Analog outputs include 2 × RCA as well as 3.5 mm and 6.35 mm headphone outputs.
A 4-band switch filter offers a substantial degree of EQ — from warm and smooth to transparent and incisive — adding extra flexibility and user control. For headphone listening, Hugo 2 also features three digital crossfeed modes.
Four spherical control buttons use colour coding to indicate performance, input, filtering and crossfeed settings.
Battery life is around 6+ hours (depending on headphones). Two automatic charging modes are included via the dedicated micro-USB charging port; an indicator shows charging and battery status.
