Press Reviews

  • 'The Unico 150 is something of a powerhouse. It delivers an immensely muscular sound mixed in with a large dose of fun… Muscular, energetic presentation, huge scale, strong dynamics, refinement, fluid midrange.' (What Hi-Fi Magazine February 2016)

  • ‘The three-piece front panel is crisply machined and the rest of the casework feels immensely solid. Neat details such as the classy-looking RCA socket used and Unison Research branded speakers connections lift the 150 above the norm.’ (What Hi-Fi Magazine February 2016)

  • ‘The Unison Research is a smooth performer with a lively and articulate nature, though that isn’t what grabs our attention… We are initially drawn to the presentation’s scale and authority. It sounds huge, with plenty of headroom and the ability to play at furniture rattling levels without any obvious signs of stress.’ (What Hi-Fi Magazine February 2016)

  • ‘Tonally, there’s a decent balance… The Unico’s sound staging is nice and wide… There’s delicacy here and the kind of fluidity that brings to mind some of the company’s all-valve designs. It makes a decent job of rhythms too, allowing the song’s gentle momentum to build with grace.’ (What Hi-Fi Magazine February 2016)

  • ‘The amplifier’s energetic delivery works brilliantly. There’s so much drive, it’s exciting, impressively articulate and a whole lot of fun… Fun is a thing many high-end products overlook in the quest for ever more insight and refinement – we’re glad Unison Research hasn’t gone down that road.’ (What Hi-Fi Magazine February 2016)

  • ‘For some the size may be an issue, other may want a more transparent and precise performer, but we’re charmed by its big-hearted presentation.’ (What Hi-Fi Magazine February 2016)
