VA-One
With a footprint measuring just 18 x 33cm, 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.

"The VA-One might not be terribly big, but it is extremely clever." ~ Hi-Fi Choice, October 2016

Classic hi-fi for modern music lovers
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.

Design - A combination of 7 pre and power-amp valves
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 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 coloration often associated with inferior valve-based products, thanks to the highly specified output transformers.

Technology - 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.
