Hugo M Scaler technology
The world’s most advanced filter: WTA — a lifetime goal of >1,000,000 taps reached!
The Hugo M Scaler is based around the powerful new Xilinx XC7A200T FPGA, which benefits from 740 DSP cores. The enormous processing power of the device has enabled a key breakthrough in tap-length (the technical indicator of how complex the interpolation filter is). Rob Watts has eclipsed a lifetime goal of >1M taps (Hugo M Scaler has 1,015,808 WTA taps or coefficients) in the latest version of the WTA (Watts Transient Alignment) filter.
The ground-breaking figure of over 1M taps, first conceived by Watts back in 1981 to be, “essential for digital to sound good, as this allows 16-bit interpolation accuracy“, has enabled the development of sophisticated WTA filtering and upscaling algorithms allowing digital data to be output at up to 768kHz.
Perfect construction of the analogue waveform: an infinite tap-length filter
To perfectly reconstruct an analogue signal, an infinite tap-length filter is required. The original Chord Electronics 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. This ground-breaking tap-length capability enables CD-quality audio to be reproduced where the interpolated output is guaranteed to be better than 16 bits; conventional filters are no better than 2- or 3-bit-accurate in recovering transient timing information.
This technical milestone 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
Like all Chord Electronics’ products, the Hugo M Scaler is designed, engineered and entirely made in the UK. It features a precision-milled chassis, crafted from aircraft-grade aluminium and comes with a three-year warranty.
