Press Reviews

  • 'The HDV 820 is a smooth, sophisticated performer and a pleasure to use… refined, informative presentation, fluid dynamics, fine build and finish.' (What Hi-Fi Magazine January 2018)

  • 'The Sennheiser has a crisp, precise delivery that sounds wonderfully refined. It’s revealing enough to show the limitations of the recording, but also insightful enough to demonstrate some of the reasons the album is so revered in the first place. There’s plenty of detail, and it’s rendered in an understated rather than overt manner.' (What Hi-Fi Magazine January 2018)

  • 'The stereo image is expansive and stable, positioning the choir and instruments with conviction and stability. There’s a pleasing dose of outright scale too, making it easy to gauge the recording venue’s size. Large dynamic shifts are delivered with composure, the ’820 showing plenty by way of force and power.' (What Hi-Fi Magazine January 2018)

  • 'There’s much to like here. Admire, even. The HDV 820 is well made, nice to use and has an unusually precise and fluid sonic balance… The HDV 820 may not shout about its talents but that doesn’t mean it can be ignored.' (What Hi-Fi Magazine January 2018)
