Quad PA-One Valve Headphone Amplifier

Quad PA-One Valve Headphone Amplifier

The PA-One headphone amp from Quad is a point of pride for the company. It's a highly versatile unit that follows the same exemplary level of build quality and sonic warmth that one would expect from any product designed and engineered by the traditional hifi manufacturer. The PA-One is ideal for any Hi-Fi enthusiast who wishes to bring the full potential of Quad-sound to their private listening experience. Quad believe that some people using high-end headphones never fully realise exactly what they're capable of, as they are often connected to poorly matched amplification. Quad have built the PA-One to combat this. 

The adept unit features a wide range of digital and analogue connections, including Balanced, RCA, Coaxial, Optical and USB, all the while retaining a relatively compact profile. This high level of flexibility makes listening to music a simple process, without having to think about the decoding of different formats. Quad describe it as 'simple - and effective'. 

Computers/laptops have become an exceptionally popular music source, thanks to their ability to offer vast amounts of digital storage and a variety of different playback programs. The USB DAC integrated within the PA-One gives these PC-using consumers the ability to enjoy their digital music to its full potential, utilising a high quality digital/analogue conversion chipset, while the valve-amplification componentry of the PA-One amplifies this sound with a superlative level of richness and warmth. The USB connection is USB 1.1 and 2.0 compliant and will decode sampling frequencies ranging from 35kHz to 192kHz.

The valves themselves have been carefully selected, and consist of 2x6SL7, 2x6SN7, and 1xEZ81. These high-quality valves allow the PA-One to give the most up-to-date technology sources the true hifi sound that they deserve.
