In principle the QUAD VA-One follows the legendary approach set by founder, Peter Walker, to bring ‘The Closest Approach To The Original Sound’ into your home by using exemplary circuit design with high quality component selection and precision build quality. What sets VA-One apart is its integration of classic valve amplification with the ability to use a multitude of sources, both analogue and digital.
For connections you’re spoilt for choice – Users can choose to play analogue devices via the gold plated RCA terminals or digital devices with playback up to 192kHz via the Optical and Coaxial inputs. There is also a 6.3mm jack headphone output for discrete use.
Furthering its digital connections, provisions for use of computers, tablet devices and mobile phones have been made: The VA-One also has a USB B input for Mac / PC (with playback of up to 192kHz) and a wireless Bluetooth input. Using the aptX codec, even via Bluetooth sound quality is not compromised, reproducing the full audio bandwidth in exquisite detail.
Both Analogue and decoded Digital sources are fed to the integrated valve amplifier which utilises an ECC83 high impedance triode as the preamplifier, feeding an ECC82 twin triode driver and phase splitter stage. The output stage uses 2 x EL84 pentodes in a push-pull mode to deliver 15 Watts RMS per channel into nominal 6 Ohm loads (matching the majority of modern loudspeakers).
As well as providing the musically transparent and immersive sound typical of classic valves, the performance is highly detailed without the unwanted coloration that you would often associate with inferior valve amplification thanks to the highly specified output transformers.
With a continued theme of convenience, a remote control is included for source select, Bluetooth pairing and volume control – operating the large motorised potentiometer on the front panel. Also on the front panel are robust source select and Bluetooth pairing controls housed within a compact Lancaster Grey finished chassis – classically QUAD in styling.
The VA-One couples the elegance of valve topology with digital audio for an animated performance, on every device.
