The ONE HD is not just an evolution of our award-winning integrated amplifier, it’s now an all-purpose ‘High-Resolution’ integrated amplifier capable of connecting directly with your PC, TV, games console, in fact, almost any source to give you simply astonishing sound quality.


The High-Resolution USB connection allows up to 192khz, 32bit music to be streamed directly from your PC or Laptop and there’s a host of other analogue and digital inputs. The built-in phono stage and superb headphone amplifier make this one of the most versatile amplifiers around today.


The Cyrus ONElinear is a premium loudspeaker system, which, whilst designed to perfectly augment the ONE Series amplifier systems, provides exemplary performance with a whole host of audio systems.


The ONElinear is engineered with a classically ‘British’ linear frequency response curve. The objective is complete neutrality, allowing the full character of the music to be revealed. A loudspeaker, however, can only be truly perfected if it is known which amplifier system will be driving it. In this case, the ONElinear has been optimised for use with our own hybrid Class D amplifier topologies
