Cyrus ONE Cast Streaming Amplifier 


The Cyrus ONE Cast - Cyrus now gives you full streaming capability, you can stream music in high quality directly from your phone using Spotify, Deezer, Amazon Music, iTunes, Qobuz and Tidal, so pretty much every music streaming service. If you have any voice assistant smart speakers on the same wifi network, you can use voice commands to send any music directly to your ONE Cast, better yet, you can set it up as part of a group for true multiroom audio. The ONE Cast does not need a separate app to stream, just like a smart speaker, you simply connect directly to the ONE Cast using whichever streaming service you use on your phone. It will all be up and running within a matter of a couple of taps on your phone.

Amplifiers with built-in streaming are now becoming a must-have part of peoples' everyday hifi set-up, so Cyrus took advantage of this and made the ONE Cast connect directly to practically anything that produces audio. From Mobile phones, laptops, game consoles, record players, radio and even your television. Another benefit of having the CAST One is that it has its own class-leading headphone so you can have some time to yourself with phenomenal sound behind them.

The Cyrus ONE Cast is quite arguably the most innovative audio amplifier available on the market today. Not only does this boast 100 watts per channel but it also uses bleeding-edge technology developed at Cyrus' Cambridge headquarters, making it super versatile to drive pretty much any sort of loudspeaker with ease.

Having used the Cyrus one cast extensively in the shop we have found that it pairs well with a wide variety of speakers - below we have listed a couple of our favourites and why

Monitor audio Silver 50 - This compact bookshelf speaker has the performance of a much larger speaker, now in a much smaller cabinet.  Monitor Audio says "the Silver 50 7G brings studio precision to your living room, in a design optimised for the acoustics of an ordinary home" this means deep bass with a wide sound stage in a compact design

Dali Opticon 2 MKii - Better suited to a medium-sized room than our previous speaker, the Opticon is designed, engineered and built in Denmark. Thanks to its larger cabinet design the speaker can handle higher sound pressure levels which help the speaker reach deeper lows. The mixture of paper and wood fibre used for the 6½" driver's diaphragm gives it the distinctive DALI trademark colour and its low distortion and low colourisation of sound.

Wharfedale Evo 4.4 - For those of you who have a bigger room to fill, the Evo 4.4 will give you an incredibly musical and detailed sound thanks to its AMT treble unit (Air Motion Transformer) matched with a high-efficiency dome midrange and a low distortion bass driver. This speaker offers an incredibly full-bodied sound and is easily placed in a room thanks to the SLPP bass reflex system. The Evo 4.4 has also won the best floor-standing speaker in the What Hi-Fi awards 3 years running.
