There’s something undeniably beautiful and alluring about a valve amplifier. Is that just nostalgia or is there really some secret behind the captivating sound? As most of us know, so-called advances in technology don't necessarily mean a better life and amplification is definitely a contender. Just look at the live music scene where valve guitar amps are still the choice of many. 

Therefore Quad - the UK name synonymous with valve amplifiers - is proud to deliver you the PA-One Headphone Amplifier, a highly versatile and user-friendly amplifier that has been designed to be the perfect match for any Hi-Fi music devotee. The past few years have seen phenomenal growth in the sales of headphones. However, most high quality headphones never realise their full potential because they are normally connected to poorly matched amplification.

Well, with Quad’s dedicated Headphone amplifier that is all about to change. The Quad Headphone amplifier is dedicated to achieving the full potential of any set of headphones connected to it. An amazingly wide variety of digital and analogue sources - Balanced, RCA, Coaxial, Optical, USB, makes it easy to listen to music without ever having to ponder on decoding different formats. Simple – and effective.

With the increased popularity of computers as source, the PA-One USB DAC allows consumers 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.

Finally, Quad engineers have incorporated the PA-One with valve amplification. 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. Indeed the closest approach
