Product Description

Quad PA-One + Valve Headphone Amplifier, DAC And Digital Preamplifier. 

Headphone Amplifier

A highly versatile and user-friendly valve amplifier that has been designed to be the perfect match for any headphone devotee. Simple and effective with an amazingly wide variety of digital and analogue sources – balanced, RCA, coaxial, optical, USB; make it easy to listen to music without ever having to ponder on decoding different formats.

Whats new?

Quad PA-One+ Valve Headphone Amplifier features a re-engineered board for a greater output power of 500mW into 32ohms, broader frequency response and vastly enhanced signal to noise ratio. The inclusion of an improved ESS Sabre 9018 K2M DAC enables PCM playback up to 384kHz and DSD256. The internal QUAD valve circuitry is also redesigned for more efficient performance. In a glance:

Re-engineered circuit topology for better freq. response and S/N Ratio
Improved circuitry for better transparency
Better DAC: ESS Sabre 9018 K2M DAC up to PCM 384kHz & DSD256

We’ve Come A Long Way

The landscape of how we consume and listen to music has radically changed. Over-ear headphones have seen a massive rise in popularity and that’s because put simply – they sound better than ever. With over-ear headphones, bigger is better. Larger drivers, larger headband, more detail, a wider frequency response and all-around better performance – you can finally enjoy a high-end hi-fi sound in a completely personal experience.

However, there’s one weak link. The devices we’re enjoying our digital music collections with cannot perform to the same high standard. While ultra-thin laptops and super-fast computers are a more than a convenient host for online streaming services, unfortunately, their headphone inputs are not equally matched...

Get The Best Out Of Your Headphones

…The Quad PA-One, however, is dedicated to achieving the best possible sound quality of any set of headphones connected to it.

A whole host of connections, both analogue and digital-driven by hi-fi amplifier valves bring an exciting detail to your music.

With a nod to Peter Walker’s styling and topology of his original valve amplification and superior quality from aesthetics to audio make a truly exquisite amplifier. The sound is full of life, yet without the unwanted colouration, many would expect from such amplifiers. The genuine heritage of Quad has been preserved with all the features to enjoy modern audio mediums.

Classic Meets Contemporary

Quad engineers have relied on valve technology for our trademark sound. Referencing the high standards set by the Quad II, valve amplifier as a benchmark, we’re sure you can enjoy a level of audio fidelity which we have consistently delivered since 1936, this time packaged into a personal hi-fi experience.

Carefully selected hi-fi amplification valves; 2× 6SL7, 2 × 6SN7, 1 × EZ81, allow the PA-One to deliver the latest technology in perfect harmony with traditional hi-fi.

True to tradition, the front panel is dominated by a large volume and balance control, while input select and impedance mode controls are in keeping with the rest of our product range for a perfect match.

The valves and electronics are housed in a Lancaster Grey steel chassis which is compact enough for a stand-alone space-saving setup, while it can also be an integral part of a high-end, large-scale system.

Connect With Your Music

An amazingly wide variety of digital and analogue sources are on hand. Balanced, RCA, Coaxial, Optical and USB, makes it easy to listen to music without ever having to ponder on decoding different formats. Simple and effective. Additionally, low impedance and high impedance modes enable connection to a plethora of modern, popular headphones.

With the increased popularity of computers as the source, the PA-One USB DAC allows you to enjoy listening to digital music sources from a computer or laptop (Windows or Mac) via USB connection.

The PA-One is USB 1.1 and 2.0 compliant and supports sampling frequencies ranging from 35kHz to 192kHz, a real treat for any hi-fi enthusiast.

With dedicated gold-plated RCA outputs, the PA-One is a pre-amp in its own right and can be integrated into part of a larger hi-fi system, too.
