What’s 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.

Premium Valves

Quad PA-One+ uses carefully selected dual 6SL7 and dual 6SN7 amplification valves to deliver the latest technology in perfect harmony with traditional Hi-Fi.

Designed to help high-end headphones reach their full potential through radically improved amplification, the effortless and effective PA-One+ supports a remarkably wide selection of digital and analogue sources so you can enjoy music without needing to worry about decoding different formats.

Connectivity

PA-One Plus offers a range of analogue inputs for maximum versatility including gold plated RCA input, 6.3mm headphone jack, 4-pin XLR balanced headphone input, 3-pin XLR balanced input and gold plated RCA pre-out (for use as a Pre-amp).

Press Reviews

  • 'HiFi World 5 Globes... Easily the best headphone amp out there' (Hi-Fi World magazine, August 2015 for the PA-One)

  • 'Much like any good valve amplifier, the PA-One brings the dynamism of the valve sound. as well as its smoothness, to headphone listening. With my Fidelio X1s synergy was almost perfect: their low sensitivity was of no consequence at all. With my classic rock test track of the Eagles careering through 'Somebody' (ripped from CD to 24/96) the PA-One kicked them hard, putting muscle behind Schmit's strenuous bass line that seemed faster than I can usually hear it...swapping over to Oppo PM-1 planar magnetic headphones showed the PA-One is relatively unaffected by headphone balance. The Oppos usually sound quite warm up top but the PA-One imposed its own will and dynamism, lessening this quality' (Hi-Fi World magazine, August 2015)

  • 'If you really value headphone listening then the PA-One is a must-have. It suits all headphones and really kicks them into life. With superb dynamics and easy-on-the-ear smoothness...this unit is easily the best headphone amp out there, providing you don't want to carry it around in your back pocket!' (Hi-Fi World magazine, August 2015)

  • ''Verdict: One of the best sounding headphone amplifiers available, a wide range of inputs offering unrestricted hi-res PCM playback' (Hi-Fi World magazine, August 2015)
