The Chord Hugo M Scaler is a reference-grade standalone digital upscaler designed to dramatically enhance the performance of compatible digital-to-analog converters by reconstructing digital audio with unprecedented timing accuracy. Developed by Chord Electronics and engineered by Rob Watts, the Hugo M Scaler utilizes an exceptionally powerful custom-programmed FPGA running the latest generation of the proprietary Watts Transient Aligned (WTA) filter. Unlike conventional digital interpolation methods, the M Scaler performs advanced upsampling using over one million taps, allowing it to reconstruct transient information with extraordinary precision before the digital signal reaches the DAC. This process significantly improves timing accuracy, spatial realism, instrument separation, and overall musical coherence. The Hugo M Scaler is designed to work with virtually any DAC via standard digital outputs, while delivering its full performance potential when paired with Chord DACs such as the Hugo TT 2, DAVE, or Qutest through its dual-BNC outputs. Supporting PCM audio up to 768 kHz, the M Scaler converts incoming digital signals into ultra-high-resolution data streams that allow compatible DACs to reproduce music with enhanced detail, smoother transients, and a more natural presentation. Multiple digital inputs, including USB, optical, coaxial, and dual-BNC, provide extensive compatibility with computers, CD transports, music streamers, and network players. The precision-machined aircraft-grade aluminum chassis houses advanced digital processing hardware together with carefully regulated low-noise power circuitry that minimizes electrical interference while ensuring consistent performance. Operation is simple through illuminated controls that allow users to select inputs, output modes, and bypass functions without interrupting playback. Rather than functioning as a DAC itself, the Hugo M Scaler serves as a dedicated digital processing component that elevates the performance of existing digital playback systems by delivering an exceptionally refined data stream to downstream converters. The result is improved soundstage depth, more accurate imaging, greater micro-detail retrieval, and a listening experience that more closely resembles the natural timing and realism of live music. Combining groundbreaking FPGA processing technology with meticulous engineering, the Chord Hugo M Scaler is widely regarded as one of the most advanced digital upscaling solutions available for reference-level audio systems.
