Hugo 2 DAC Design

0 Flares Filament.io 0 Flares ×

The Chord Hugo released in 2014 was a game changer in the DAC industry as we shared in 2014 here.  As Chord Electronics started the Hugo 2 DAC design, they looked for everything that could be improved upon with the original Hugo. Chord read the forums, listened to feedback from Hugo owners, and thus engineered flexible new features with next-generation technical and sonic performance.  

The Chord Mojo was developed for mobile applications from the success of the Hugo and now leads the mobile DACs industry. The Hugo could be used both as a mobile and as a desktop device. The Hugo 2 can be used at home, on-the-go, either with headphones or with a conventional home audio system. 

Hugo 2 DAC Design

The shape of the Hugo 2 is similar to its predecessor, but Chord has sharpened the edges with Flush Mount I/O to allow for easier connections. This new design also works with thicker ended cables. 

Chord’s Hugo 2 has been reduced to 1 Micro USB Input which is indicated by a White Light for HD USB. You can play and charge Hugo 2 at the same time with the separate Micro USB Charging input .

It takes 4 hours (2amps) / 8 hours (1amp) to charge the Hugo 2 with an average 8 hours playback. The Hugo 2 adopts the same battery light indication as the original Hugo:

Hugo 2 Connections

Hugo 2 allows the following inputs:

  • Bluetooth up to 45 meters – A2DP Bluetooth capability just like the HugoTT
  • Optical 24-BIT/192kHz
  • Coax Digital 3.5mm – 24-BIT/384kHz x2 (Coax 1 = tip and sleeve / Coax 2 = ring and sleeve)
  • RCA Analogue (Right / Left)
  • Headphone output 3.5mm (1/8″)
  • Headphone output 6.35mm (1/4″)

 

Hugo 2 Features

The Second Generation Hugo 2 includes Intelligent filtering to change the sonic presentation. The HF filter is optimized for DSD playback. 

  • Filter 01 (White):  256fs = Incisive Neutral
  • Filter 02 (Green): 256fs + HF roll-off = Incisive Neutral with high-frequency roll-off
  • Filter 03 (Orange): 16fs = Warm
  • Filter 04 (Red): 16fs + HF roll-off = Warmer with high-frequency roll-off. 

Crossfeed also gives a more-speaker like presentation with three-stage DSP spatial effect.
