Next-generation Hugo 2 revolutionises Chord Electronics’ game-changing debut portable DAC/amp
Hugo 2 adds new features, state-of-the-art performance, plus an all-new chassis design

5th January 2017, CES, Las Vegas: Chord Electronics has unveiled Hugo 2, a dramatically redesigned version of its legendary portable DAC, featuring all-new casework, flexible new features, plus next-generation technical and sonic performance (£1,800)

Three years ago at CES 2014, Chord Electronics unveiled a revolutionary portable DAC and headphone amp that became a landmark product in the audio landscape. Recent advances in digital technology have enabled Chord to introduce the next-generation version: Hugo 2.
The new device has been comprehensively upgraded while ensuring continuity with the much-loved original. It introduces the latest proprietary Chord Electronics FPGA technology giving cutting-edge technical and sonic performance, plus exciting new features.

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 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 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.

Chord Electronics redefines CD performance with 
its new FPGA-based upscaling transport Blu MkII
New Blu MkII offers the world’s most advanced filter technology from its giant FPGA core

5th January 2017, CES, Las Vegas: Chord Electronics has set new standards for CD sound quality with its new Blu MkII, an upscaling CD transport which uses the very latest FPGA technology to implement advanced proprietary filtering and upscaling techniques £7,995

Known for its world-class amplifiers and its class-leading FPGA-based (Field Programmable Gate Array) DACs, Chord Electronics has implemented the latest FPGA technology into a next-generation CD transport. The new Blu MkII, which will replace the original Blu, incorporates a powerful new FPGA core with extraordinary capability.

Chord Electronics’ Digital Consultant, Rob Watts, has harnessed the power of the new Xilinx XC7A200T FPGA, which has a standout 740 DSP cores, to develop sophisticated WTA (Watts Transient Alignment) filtering and upscaling algorithms which can output digital data at 705.6kHz (16 x CD’s 44.1kHz native resolution). When partnered with the critically acclaimed DAVE DAC/preamp, with its 705.6kHz-capable digital inputs, the Blu MkII sets a new technical benchmark for CD performance, while redefining sound quality from the medium.

At the heart of the Blu MkII, lies Rob Watts’ new WTA M-Scaler technology, which incorporates the most advanced filter of its kind in the world. Rob Watts has developed completely new filter architecture for the Blu MkII, to ensure maximum memory efficiency and to allow the FPGA to run with sufficient speed.

The enormous processing power of the Xilinx XC7A200T FPGA has enabled a key breakthrough in tap-length (the technical indicator of how complex the interpolation filter is). To perfectly reconstruct an analogue signal, an infinite tap-length filter is required. The original Chord DAC 64 (1999) had 1,024 taps; Hugo (2013) 26,000 and DAVE (2015) 164,000. Each successive increase in tap-length, together with continuous improvements to the WTA algorithm, has given significantly better sound quality.

The new Blu MkII offers an incredible 1,015,808 taps! This remarkable capability takes transient accuracy to a completely unprecedented level: it becomes simpler to perceive the leading edge of transient notes, creating a life-like sound-field. Bass definition is massively improved, with greater ability to follow the tune. Sound-staging, instrument separation and focus are also noticeably better, along with vastly improved variation in instrument timbre.

Blu MkII with DAVE: the world’s most advanced CD playback system

The Xilinx XC7A200T consumes an enormous 10 amps of current, so it couldn’t be implemented in DAVE as the sheer amount of current could upset DAVE’s comprehensive signal-processing. The engineering solution was to isolate this new FPGA and employ an external scaler — Blu MkII has (RF-isolated) 705.6kHz outputs to feed DAVE directly. The combination has created the world’s most advanced CD playback system.

Completely revised on the outside, too

The Blu MkII has also undergone extensive revisions on the outside. Chord’s Chief Designer, John Franks, has streamlined the aesthetic with a beautiful new top-plate that simply features the most commonly used functions. A useful display gives track information etc. and Chord’s elegant hinged self-supporting lid design offers a touch of class when loading/removing discs and positions the disc-puck perfectly. It also automatically stops play when lifted. A full remote offers further control options.

A comprehensive suite of high-performance connectivity is offered, including (for the digital outputs): AES (to 176.4KHz); single optical, single S/PDIF and dual BNC S/PDIF; the dual BNC S/PDIF output transmits up to 768kHz into Chord’s DAVE DAC/preamp using twin cables.

The Blu MkII also features a BNC S/PDIF digital input, meaning that it can also be used a standalone high-performance upsampler, for use with other digital sources, such as streamers, in addition to its primary function as a CD transport. This enables a digitally connected device to benefit from the Blu MkII’s advanced FPGA technology and if deployed, DAVE’s class-leading digital-to-analogue conversion.

Further features include Chord Electronics’ legendary proprietary high-frequency switching power supply and a dedicated CD-only laser mechanism for an uncompromising performance. A dedicated equipment support (in the Blu MkII/DAVE image) is also available for a supplement.

Like all Chord Electronics’ products, the Blu MkII is hand-made in the UK and features a precision-milled chassis, crafted from aircraft-grade aluminium.
