Chord Qutest Desktop DAC

Description

Qutest

Qutest is uniquely equipped to bring the benefits of Chord Electronics’ acclaimed proprietary hardware and software technology to a wide range of connected devices. It features a galvanically isolated USB-B, plus optical and dual coaxial digital inputs. This gives an instant upgrade to everyday audio devices, plus the ability to modernise ageing digital source components.

It also features RCA analogue outputs for connection to integrated amplifiers, preamps and headphone amps. Plus high-resolution 768 kHz-capable dual-data digital inputs for connection to Chord Electronics’ devices – including the 705/768 kHz-ready M-Scaler-technology BLU MKII digital/CD transport.

Qutest offers support for up to 32-bit/768kHz PCM and DSD512 via its galvanically isolated USB-B input, 24-bit/384kHz PCM and DSD128 via coaxial (BNC) and 24-bit/192kHz data on Optical TOSLink. DSD 64 to DSD 256 is supported via DoP and ASIO native DSD format is also supported up to 512.

The device features a Class 2 USB input which, because of the Qutest’s home-system orientation compared to Hugo 2’s more mobile aspirations, has been galvanically isolated. This has been achieved using a novel technique which allows for very high data rates of up to 768kHz; the input is driverless on Apple and Android devices, with (ASIO included) drivers for Windows devices.

The Qutest chassis is all-new. It has significantly greater mass than its predecessor and has been precision-machined from solid aircraft-grade aluminium billet. The Qutest PCB nestles within a shallow cavity in the solid aluminium chassis, giving the circuit board greater protection within the casework and additional isolation from external vibration compared to previous designs.

Qutest’s new square-edge chassis design created by owner and Chief Designer John Franks retains the popular circular magnifying porthole window, which reveals the custom Chord Electronics’ circuit board within. Qutest’s control spheres (for user-selectable frequency-shaping and input selection) illuminate with useful colour-coding information denoting sample frequency and filter used; brightness settings are user-adjustable. A further new feature is a user-selectable output voltage available in 1, 2 and 3V RMS outputs for flexible connectivity with partnering devices.

The latest FPGA and advanced WTA (Watts Transient Aligned) filters have been implemented in the Qutest, bringing a wide variety of performance improvements over the 2Qute in a number of areas. Performance gains have been made in timing accuracy, noise reduction and dynamic range and tap length, the technical indicator of how complex the interpolation filter is, has more than doubled compared to its predecessor, to 49,152.

A four-function switch filter, operated by its own control sphere, offers a useful degree of user-selectable frequency-shaping, bringing warm and soft or transparent and incisive presentations, giving additional flexibility and user control.
