Press Reviews

  • 'You’ll struggle to find better detail or dynamics from a headphone amp and USB DAC.' (What Hi-Fi Magazine September 2015)
  • 'The bareness of the arrangement exposes just how intricate and faithful the HA-2’s expression is... that character is reflected in the handling of the vocal. The harmonies are full, yet you can hear each voice. It sounds natural, but most importantly it is engaging.' (What Hi-Fi Magazine September 2015)
  • 'It’s a combination of dynamics, timing and detail regardless of the genre to which you’re listening that makes the Oppo so adept. Partner that with the portability, compatibility and creativity of the design, and we’d struggle to recommend anything else.' (What Hi-Fi Magazine September 2015)
  • 'Unlike the dedicated audio players, the Oppo can provide the same boost to a computer and does so while looking and feeling fantastic, offering a truly killer specification and providing trickle charge functionality for your portable device.' (AV Forums May 2015)

  • 'Whilst the specs of the HA-2 are all perfectly sound, they don't cover the emotional angle that the Oppo is also a gorgeous piece of equipment.' (AV Forums May 2015)

    Bought one of these off the back of all the positive reviews and have been really impressed with it; the battery lasts a reasonable amount of time and it sounds much better than the output on my phone.

    I recently bought the HA-2 and cannot recommend it heartily enough. It is easy to use, the battery outlasts the player by some considerable margin and the sound is superb. I match it to my iBasso DX-90 and Oppo PM-3 and the world just disappears in front of me!
