Using technology first seen in the flagship BLU MKII digital/CD transport, the Hugo M Scaler is a standalone upscaling device containing the world’s most advanced digital filter. When used with a dual-BNC-input Chord Electronics DAC, it is capable of redefining digital audio sound quality.

The 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 unrivaled advantages of our ground-breaking FPGA-based WTA (Watts Transient Alignment) filtering technology to digitally connected audio devices, dramatically improving sound quality. Although optimized 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 its price point, redefining sound quality from digital audio.


M Scaler Technology Profile

The Power of Upscaling

The M Scaler is an instant upgrade to any existing DAC you have. It has the ability to upgrade your standard definition digital input signals and output them to your DAC at a max resolution of 352.8 or 384kHz via a single BNC SPDIF output or via a 176.4 or 192kHz via an Optical SPDIF output. If you have a Chord Electronics DAC that utilizes Dual Data Digital inputs, such as the Chord Qutest, Hugo2, Hugo TT2 or the Dave, then you can increase this output resolution to 705.6 or 768kHz via the M Scaler Dual BNC SPDIF outputs. The Hugo2 requires a special cable for the 3.5mm dual data input, so we've developed a Black Dragon Mini Coax Cable to connect it to the M Scaler.

Keith Howard wrote a wonderful profile on Rob Watts' theories of why the upsampling filters are so critical to remarkable digital audio playback. Read the Hifi Critic article here.
