Cyrus ONE HD Integrated Amplifier

This model sits above the standard Cyrus One, benefiting from all the same great performance features with the addition of a 32-bit DAC.

Cyrus One HD Integrated Amplifier with DAC is not just an evolution of the award-winning amplifier, it’s now an all-purpose ‘High-Res’ integrated amplifier capable of connecting directly with your PC, TV, games console, in fact, almost any source to give you simply astonishing sound quality.

Bluetooth aptX HD
Compatibility with aptX HD Bluetooth enables you to stream better than CD quality music from your phone/tablet or computer via a wireless Bluetooth connection, providing maximum flexibility without the need for a home network or any complicated setup. This allows everyone in the family to enjoy their music from their portable devices quickly and easily.

High-power Amp
Twin 100W per channel gives class-leading power output that will drive most loudspeakers regardless of their size. All that power enables Cyrus One HD to present your music with a huge dynamic range, giving 3D detail and bags of energy without the need to buy big, bulky, inefficient amplifier boxes.

MM Phono Stage
Cyrus One HD features a built-in phono stage that is compatible with all Moving Magnet cartridges and requires no adjustment or extra set up, enabling you to play all your favourite vinyl from most turntables. It is now on its own isolated circuit board and every part of the amplifier circuit and linear power supply have been reworked.

Digital/analogue in
Asynchronous USB, optical and SPDIF inputs enable you to connect your PC, TV, Games Console, CD player, indeed virtually any source, directly to the Cyrus ONE HD. Four analogue inputs include RCA terminals for a turntable and an AV input that can be set to fixed gain to allow integration with a separate AV amplifier.

Class AB Amplifier
The in-house designed hybrid Class D amplifier has been upgraded to a fourth-gen version. When headphones are connected, the large toroidal transformer is switched to power just the headphone section. These huge reserves of power result in a high power, high voltage class AB headphone amplifier that will drive almost all headphones with ease. The resulting musical performance is on a par with most standalone headphone amplifiers

Impedance Adjustment
Speaker Impedance Detection automatically matches the amplifier’s output response to the electrical load of the loudspeakers. This means that matching Cyrus One HD to any brand of the loudspeaker has suddenly been made so much easier.


Cyrus One Linear Speakers

This compact bookshelf speaker pair is a precision stereo loudspeaker system for use with hi-fi separates, designed for positioning 10-30cm from a rear wall.

Cyrus One Linear Speakers is a premium loudspeaker system which, whilst designed to perfectly augment the Cyrus One amplifier, provides exemplary performance with a whole host of audio systems.

The One linear is engineered with a classically ‘British’ linear frequency response curve. The objective is complete neutrality, allowing the full character of the music and the subtle details of the performance to be revealed.

Long Listening
A loudspeaker can only be truly perfected if the amplifier system that is driving it is known. In this case, the One linear has been optimised for use with our own hybrid Class D amplifier topologies. The One linear is designed to be as relaxing and enjoyable after many hours of listening as it is attention-grabbing and impressive in the first 10 minutes.

Bass/Mid driver
The One linear bass/mid driver uses a double-wound copper-coated aluminum voice-coil. As well as being light, this produces a stronger induced magnetic field which gives greater grip over hard to control bass frequencies. The voice coil is bonded to a carefully profiled Kevlar cone material.

This material is light and responsive, carrying limited inertia and retaining its shape and hence audio characteristic even when pushed hard. The speed and accuracy of the resulting bass response is remarkable for a speaker of this size.

The ‘tweeter’ or treble unit is a textile soft-dome, capable of meaningful response well beyond the limits of human hearing. Refined and balanced, the high-frequencies are never ‘aggressive’ or harsh, yet retain the full detail of the source recording.

The crossover uses high-quality electrolytic capacitors to maintain the signal integrity and a smooth phase response through the transition from bass driver to tweeter. This again contributes to the even response.

The cabinet has been developed using advanced computer modeling with ‘Delayed Cumulative Spectral Analysis’ to reduce the contribution of cabinet noise to levels more than 35dB below the driver output. This is also used to fine-tune the crossover to ensure a consistent performance, even when listening ‘off-axis’.

The One linear is rear-ported and designed to be positioned between 10-30cm from a rear wall. This will optimise the bass response and mid-range clarity, although some experimentation with position is advised as this will be room-dependent.
