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.

Where to buy

“Quite simply the no-brainer of the year” – Hi-Fi Choice, April 2018


The concept for the ONE streaming bundle is to provide everything you need to build an incredible streaming audio system at an outrageous price. Simply stunning fidelity and power underpins the performance of the Cyrus ONE. The ONElinear speakers have been designed to make the best possible use of this power and deliver a whole which to again quote Hi-Fi Choice, “Borders on the heroic”.


The reason? Well, for a loudspeaker designer to be able to optimise a design for a specific amplifier is a rare situation. In our case, the ONElinear was designed to be a good loudspeaker with all amplifiers, but a ‘great’ one with the unique class D topology used in our Cyrus ONE, Lyric and Stereo 200 models. Capable of handling the significant transient response possible with the Cyrus ONE, especially at bass frequencies, the ONElinear transforms into a performer which would shame much more expensive models.


The ONElinear loudspeakers, although excellent as stand-alone speakers, are fully matched for use specifically with these ONE series amplifiers. Capable of drawing every last detail and nuance from the amplifiers, they will deliver a performance which belies their small size.

Supplied as a hi-fi starter kit, this package includes audiophile-grade loudspeaker cable. One again, matched specifically for this amplifier/speaker combination, the cable uses an Aluminium core, with ‘oxygen-free’ copper skin. The detail is enhanced, as is control over the lower frequencies.


Connect up your TV, CD player, or turntable to the amplifier and you have a complete hi-fi system from one of the leading names in high-quality British audio.


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.
