Chord Electronics Hugo M Scaler

The Chord Electronics Hugo M Scaler is a highly advanced standalone upscaler capable of redefining sound quality from digital audio. It uses Rob Watts’ (our Digital Design Consultant’s) unique filter technology, the most advanced in the world, to upscale standard 44.1kHz digital audio up to 705.6kHz (16x CD’s 44.1kHz native resolution), ready to be passed to a suitable DAC; Hugo M Scaler extends its upscaling performance to 768kHz (from 96kHz input data) for our dual-BNC-input DACs: DAVE, Qutest and the new Hugo TT 2.

The Hugo M Scaler brings the unrivalled advantages of our ground-breaking FPGA-based WTA (Watts Transient Alignment) filtering technology to digitally connected audio devices, dramatically improving sound quality. Although optimised for use with selected Chord Electronics DACs (for the maximum 768kHz upscaling/decoding benefit), the Hugo M Scaler can be used with other DACs with suitable inputs, subject to their decoding capability.

The Hugo M Scaler’s compact form factor aligns with the TT (Table Top) series and has been designed to be stackable with other units in the range, including the TToby stereo power amp and the Hugo TT 2, to form a highly advanced yet space-saving system. In line with other models in the Hugo and Hugo TT series, the device features a number of illuminable fascia-mounted spherical controls, governing input selection, output sample rate and video mode for lower latency. The control spheres display data visually including input source and the incoming sample rate, using a polychromatic scale.

When partnered with either of Chord Electronics’ 768kHz-capable dual-BNC-input DACs, the Hugo M Scaler sets an astonishing technical benchmark for digital audio performance at it price point, redefining sound quality from digital audio.

  1. Simone Ragionieri Simone

    As a Chord DAVE owner, I was attracted by the M Scaler (1 million taps) technology first introduced by Chord in the Blu Mk2 upscaling CD player, also given the stellar reviews.

    When Chord presented the Hugo M Scaler, where this technology has been made available in a standalone scaler, I immediately pulled the trigger preordering mine.

    My expectations were high, but at the same time I was thinking that the DAVE on its own was so good that the improvement could only have been marginal, and the feedbacks I was reading on the internet were typical audiophile hype.

    After receiving my unit and plugging it into the DAVE via the dual BNC connection, it took only SECONDS to realize I was simply listening to a different DAC 🙂

    The effect of the M Scaler is very apparent to my ears, as it provides to the already eccellent DAVE a significant amout of those qualities I use to relate to good analog sources (and live music, of course), like the sense of effortlessness, flow, smoothness, palpability, cohesion, while retaining its transparency, imaging, speed and dynamics.

    I am very happy with the Hugo M Scaler purchase!

    Awesome unit. For me, the benefits of using it have been subtle, but also pretty fundamental. Most of the music I listen to is forward-looking electronica, and M Scaler has had two major effects for me: firstly, an utter _utter_ lack of fatigue when listening on headphones; and secondly, the ability to listen to (and enjoy) very dense ‘wall-of-sound’-style music.

    So for the first point – I can quite happily listen to music all day, no worries at all. I simply never get to the point where I need a break. Before M Scaler (and this is still with a decent pair of headphones) I’d get to perhaps a couple of hours before I’d need to headphones-off for a little while.

    For the second – stuff like Jlin’s ‘Black Origami’, Blanck Mass’s ‘World Eater’, pretty much anything on Nyege Nyege Tapes, that I found a really tough listen to before, are now actively pleasurable. There’s just something about M Scaler’s ability to unpack density that makes it really special.

    And there are certain tracks that I’ll happen across when digging back into my library or across Qobuz that’ll just stop me in their tracks with their sheer emotional wallop – listening to the M-Scaled version of Nirvana’s MTV Unplugged album for the first time, say, or fka Twigs’ ‘Cellophane’.

    Fantastic bit of kit that’s earned itself a permanent place in my setup.

    (for reference: Roon -> Node 2 -> (Audioquest Forest Optical) -> M Scaler -> (freebie dual BNCs) -> Hugo TT2 -> (stock cables) -> Meze Empyreans.)
