With ONE Cast you can stream music in high-quality directly from your phone using Spotify, Deezer, Amazon Music, Apple Music, Qobuz, Tidal – in fact, almost any streaming service over Wi-Fi. If you have voice assistant smart speakers on the same Wi-Fi network, you can use voice commands to send music directly to your ONE Cast smart amplifier or even set as part of a group for true multiroom audio.

As the centre of your new smart home audio system, ONE Cast will connect directly to virtually anything that produces audio. From mobile phones over Wi-Fi, laptops through USB, games consoles, record players and radio stations over the internet. You can even connect your Smart TV to ONE Cast using HDMI. It even features a class-leading headphone amplifier for late-night listening.

The Cyrus ONE Cast is arguably the most innovative stereo amplifier available today. Boasting 100 watts per channel and using bleeding-edge technology developed entirely at our Cambridge headquarters, this smart amplifier is capable of driving any loudspeakers with unerring ease from anywhere in the house.

As its name suggests the ONE® Cast is a Cast enabled device. So using any streaming service on your mobile, tablet or laptop which is Google cast compatible (such as Spotify, Tidal or Qobuz) and you can throw the music at the ONE® Cast . Airplay 2 is also built in, so apple users will be able to divert sound from any app to the ONE® Cast.

The amp still has S.I.D. (Speaker Impedance Detection) which calibrates itself to perform optimally with any loudspeaker it encounters. With 2 x 100W of power, it is capable of driving even notoriously difficult speakers to exceptional standards. Digital inputs now include HDMI (ARC), so you can connect the amp directly to your TV and control it the volume from the TV remote.

All the digital inputs are fed into a high-resolution ESS® 32-bit DAC specifically engineered to produce an optimum performance. The built-in MM phono stage is separated from the main circuit, lowering the noise-floor and providing an even better performance when directly connected to a turntable. Reacting to feedback on previous ONE series products, the ONE® Cast comes with a new IR remote control (for when you’ve lost your voice).


Cast and Airplay Enabled

Any streaming or music playing app which is Google cast compatible can be played via the ONE® Cast. Simply launch the app, hit play, and then select the ONE® Cast from the cast button. The ONE® Cast then takes over the hard work, pulling the data from the cloud and converting it to an enthralling musical experience in up to 24/96 high resolution. Apple airplay is also on board, providing a similar ease of use for Apple users.

Voice Control Compatible

Whether you have chosen to go down the Apple, Google, or Amazon Alexa route for you home smart speaker, you can control the ONE® Cast simply issuing the appropriate commands. Set up is child’s play, through either the Google home app, or Apple Airplay.

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® Cast 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® Cast 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.

High Resolution DAC for Digital inputs:

The onboard ESS 32 bit DAC is capable of handling up to 32/192 source and DSD to DSD128 over asynchronous USB. Additional optical, SPDIF and HDMI (ARC) inputs give you all the connection flexibility you need. Bluetooth is also built in, and alongside the turntable input is 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 stand- alone 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® Cast to any brand of loudspeaker has suddenly been made so much easier.

The Ultimate Flexible System

The Cyrus ONE® Cast is an entire system. With the ability to cast music to it from a phone, tablet or laptop means the user can use their favourite streaming service or music playing app to choose their music or store their playlist, and the Cyrus ONE® Cast does the rest, turning it into an astounding music experience.

Voice control compatibility gives it a whole level of future proofing, as more and more people populate their homes with smart speakers. Whilst an Amazon Echo may be high quality for enough for the news, when you really want to listen to music, tell Alexa / Siri / Google to play it on your superlative Cyrus ONE® Cast, taking your music to a whole different level.

Underneath the lid is an exceptionally powerful amplifier capable of driving even large form-factor loudspeakers from almost any analogue or digital source. It remains a relevant component in high-end systems costing many thousands of pounds. But if private listening is your thing, the unit can switch all its power over to the high- performance headphone amplifier.

A perfect complement to the Cyrus ONE® Cast, the Cyrus ONE linear speakers have been specifically designed to benefit from the Hybrid Class D topology used in all Cyrus ONE models.
