“Connect your  Cyrus ONE HD with your laptop or PC via USB. The performance of high-res audio files played from streaming services such as TIDAL or Qobuz is simply jaw-dropping.”

ONE HD FEATURES

Bluetooth Enabled – aptX®HD:
aptX® HD compatible 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 set up. This allows everyone in the family to enjoy their music from their portable devices quickly and easily.

High-power Amplifier:
2 x 100W 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.

Digital and analogue inputs:
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 in order to integrate with a separate AV amplifier.

Class AB Headphone Amplifier:
Uniquely, 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

Speaker Impedance Adjustment:
SID – 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 loudspeaker has suddenly been made so much easier.
