Press Reviews

  • 'Easily the best headphone amp out there' (Hi-Fi World magazine, August 2015)

  • '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)
