The Cyrus ONE HD

Cyrus' 'ONE' is a prolific integrated amplifier, designed and engineered by Cyrus in Cambridgeshire to act as the solution for those who wish to cut down on their number of boxes and save space while refusing to compromise on sound integrity.

The Cyrus ONE HD can be controlled via a mobile app, making input selection, volume control and other settings easily accessible. The app is available on both Android and IOS and can be downloaded for free. Due to the ONE HD being controlled via its mobile app, an infrared remote is not included as standard in the box. These can be purchased as an additional extra.

The latest ONE HD has been designed with the space-conscious audiophile in mind and features a newly designed 4th generation Class D amplifier, capable of offering suitable loudspeakers with a rich and dynamic 2 x 100 watts of power. The ONE HD is built to be both convenient and versatile with its connectivity options. Audiophile-grade lossless aptX Bluetooth codec guarantees a CD-quality transmission of audio files or streaming apps from a compatible smartphone directly to the amplifier, while 4 line inputs and a Moving Magnet phonostage allow for the connection of a turntable as well as a CD player and dedicated streamer etc. 

The HD model features digital inputs like an Asynchronous USB input, Optical and Coaxial for all your digital needs. 

The headphone amplification stage of the ONE HD has also received special attention. It's high power, high voltage class AB design will drive essentially all headphones without struggle and to a deserving standard of quality. The headphone socket is conveniently located on the front of the machine, so it's easy to enjoy the quality of Cyrus for a personal listening experience.
