QUAD VA-One + Integrated Amplifier/Headphone Amplifier

Irresistible Classicism and Modernity: Quad VA-One+ Integrated Amp/Headphone Amplifier Features Seven Tubes, Bluetooth aptX Receiver, and SABRE 9018 K2M DAC for DSD256 and 384kHz

The sleek cage atop the seven-tube Quad VA-One+ valve headphone amplifier/integrated amplifier tells you almost everything you need to know about this extremely versatile component: Yes, it's all about the tubes, and the inimitable sound of the four EL84EH pentodes in push-pull configuration, two ECC82 triode drivers, and single ECC83 high-impedance triode inside. But it's also about the high-resolution ESS SABRE 9018 K2M DAC that plays up to DSD256 and 384kHz via the USB-B input – as well as the Bluetooth aptX receiver that gives you countless options.

Fully stocked with RCA, coaxial, optical, and USB inputs to match with every listening source without wondering about format decoding, VA-One+ also boasts a remote control, powerful headphone output, and two speaker terminal outputs.

Pleasingly warm, effortlessly efficient, wondrously simple, and able to deliver 12Wpc into eight ohms, VA-One+ can connect right into your computer or laptop for easy, invigorating computer-audio experiences. Have a craving to hear vinyl? VA-One will let you do that, too, when used with a phono preamplifier. With VA-One+, how you listen to music is up to you. Stream it, spin it, wirelessly connect to it. Smartphones, tablets, Macs, PCs, source components. VA-One+ does it all.

Of course, VA-One+'s super-compact footprint – 6.4 inches high by 11.2 inches deep and 7.1 inches wide – makes it ideal for tight spaces and places where are remains at a premium, like desktops and shelves. A smooth volume control with a motorized potentiometer for precise adjustment and traditional Quad aesthetics round out a feature-packed tube component that merges classicism and modernity like few others.

Classic British Hi-Fi for Modern Music Lovers
Internal components have been painstakingly selected to ensure VA-One+ maintains the company's traditional dictum of "the closest approach to the original sound," while external styling is classically Quad. The amp's front panel sports a smooth-acting volume control incorporating a motorized potentiometer, allowing precise adjustment via the supplied remote control. A high-quality headphone output and controls for input selection and Bluetooth pairing are also included. It all adds up to a 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.

Seven Preamplifier and Power-Amplifier Tubes
VA-One+ boasts an impressive complement of tubes for such a compact device. 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 15Wpc (into six ohms) – sufficient power to drive efficient modern speakers to high volume levels while 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, VA-One+ delivers lashings of musical detail without the unwanted coloration often associated with inferior valve-based products thanks to its highly specified output transformers.


24-Bit/384kHz DAC: The VA-One+ employs a 24-bit/384kHz DAC (digital-to-analog converter) with support for high resolution audio.

Bluetooth Audio Streaming: Built-in Bluetooth A2DP gives you the freedom of wireless connectivity for your smartphone, tablet, or computer. You'll be able to wirelessly stream audio from your Bluetooth source device to the VA-One+. The VA-One+ also supports the aptX codec for higher quality wireless audio for select Bluetooth-enabled source devices. A 3.5" Bluetooth antenna is included, and connects to the rear panel, for best reception.

USB-B Port: The VA-One+'s USB-B port (1.1/2.0 compliant) allows you to listen to digital music files stored on your Windows PC (7/8/10) or Mac (OS X) computer. The unit supports PCM and WAV music files up to 24-Bit/384kHz. A Windows PC will require a separate USB driver that can be downloaded from the Quad website. A 5' USB-B to USB- cable is supplied to make connection between the VA-One+ and your computer.

Optical & Coaxial Digital Inputs: The VA-One+ is also outfitted with an optical (toslink) digital input and a coaxial (RCA) digital input that supports 2ch PCM music files up to 24-bit/192kHz. The digital inputs do not support multichannel audio formats such as Dolby Digital and DTS.

Stereo RCA Input: The VA-One+ is equipped with an analog Aux input which consists of stereo RCA jacks for connection of an external analog audio device. If you want to connect a turntable, you will need an external phono preamp (sold separately - see Accessories Tab) or a turntable with a built-in phono preamp.

Binging Post Speaker Terminals: The VA-One+ provides binding post terminals to connect your speaker wire and your speakers. The binding post terminals will accept bare wire (up to 12AWG), pin-connectors, spade-lugs, and banana plugs (single only).

1/4" Headphone Jack: The Quad VA-One+ features a front-panel 1/4" headphone jack for connecting a set of headphones. The unit's speaker outputs will be muted while headphones are connected.

Simple Control: The VA-One+ has a large motorized rotary volume knob on the front panel. Source selection consists of three push buttons for the Bluetooth, AUX, and Digital inputs. The Digital Input button allows you to cycle through for selecting the USB, coax, or optical sources. The main power switch is located on the back panel. The unit also includes a small, simple wireless remote control. The IR remote can control power, speaker mute, source selection, and volume. It is powered by a CR2025 battery (included).
