The ONE system

The Cyrus ONE amplifier and ONE linear speakers provide the perfect all-in-one system from this impressive hi-fi starter kit. Connect up the loudspeakers and you’re good to start experiencing the true potential of the music from your phone, or laptop over Bluetooth.

The amplifier itself is a multi-award winning amplifier using our unique ‘Hybrid Class-D’ amplifier circuitry, perfected over several years to deliver peerless performance and staggering power.


Design philosophy Cyrus ONE / ONE linear

Cyrus ONE is a compact, yet insanely powerful and refined single box amplifier.

The simplicity of use and integration with your existing audio products are core to this product. As well as being app controllable, we’ve built in a high-quality Bluetooth receiver, so users can send music from their phones. The superb built-in ‘phono stage’ allows users to directly connect a turntable. and a highly capable headphone amp is also included.  The powerful 100-watt stereo amplifier section uses our in-house designed ‘hybrid Class-D engine’ – one of the most impressive amplifier designs of recent years.

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.
