Quad VA-One Integrated with aptX Bluetooth Lancaster Grey
The VA-One is conveniently compact for a valve amp – sufficiently small to sit comfortably on a desk, table or shelf. Yet it packs in a wealth of high-performance audio technology: a hi-res DAC (Digital-to-Analogue Converter) joins valve-based preamp and power amp circuits to deliver sumptuous sound quality from a multitude of playback devices – from smartphones and tablets, to PCs and Macs, to hi-fi source components.
Build quality is impeccable both inside and out, as one expects of QUAD. Internal components have been painstakingly selected to ensure the VA-One maintains the company’s traditional dictum of “the closest approach to the original sound”, while external styling is classically QUAD, finished in traditional ‘Lancaster Grey’. The amp’s front panel sports a smooth-acting volume control incorporating a motorised potentiometer, allowing precise adjustment via the supplied remote control, together with a high-quality headphone output and controls for input selection and Bluetooth pairing.
It all adds up to the ideal compact amplifier for modern music lovers who crave the mellifluous sound quality and delicious retro appeal of valves, whilst listening to music from all manner of modern devices, like smartphones, tablets and computers.
The VA-One boasts an impressive complement of valves for such a compact device (seven in all). The preamp section incorporates an ECC83 high-impedance triode, feeding an ECC82 twin triode driver and phase splitter stage. The output stage uses two EL84 pentodes per channel in a push-pull configuration, delivering 2x15W – sufficient power to drive efficient modern speakers to high volume levels, whilst maintaining the sumptuous sound quality derived from the amp’s valve-based topology.
As well as providing the fluid, immersive sonic performance associated with classic valve amplification, the VA-One delivers lashings of musical detail without the unwanted colouration often associated with inferior valve-based products, thanks to the highly specified output transformers.
Modern digital convenience, including USB and Bluetooth connectivity.
Three digital audio inputs – optical, coaxial and asynchronous USB – support data up to 24-bit/192kHz, and an RCA-phono input gives the option to connect an analogue source like a CD player or a turntable (when used with a suitable phono stage).
In addition, those who enjoy the freedom of wireless connectivity can pair smartphones, tablets and computers via Bluetooth, with support for the sonically superior aptX codec.

Quad
The history of Quad is one of technical achievement in the field of sound reproduction. It is a story that began with the Quad 1 amplifier, which brought the benefits of 15 years knowledge and experience in professional audio and industrial products to the task of making the most accurate domestic audio amplifier of its age.A few years later, in 1953, the product which set the standard for amplifiers was the Quad II Power Amplifier, the time of Queen Elizabeth’s Coronation and the year in which Mount Everest was finally conquered. This amplifier pioneered the principle of cathode coupling through the output transformer to reduce harmonic distortion to almost negligible levels. Such was its clear superiority that this model remained in production for 18 years. Three years later, in 1956, Quad demonstrated the first true full-range electrostatic loudspeaker. This remarkable product (known later as the ESL 57) used a virtually mass-less plastic film as a moving diaphragm between two charged plates. Compared with moving coil loudspeakers, the ESL 57 was free of unwanted colourations and distortions. This landmark product remained in production, virtually unchanged, for 28 years.
