Cyrus 40 ST Network streamer

The Cyrus 40 ST is the ultimate product for digital music lovers, offering an outstanding combination of performance, design and ease of use. As the most powerful network streamer in the 40 Series, it sets new standards in digital music playback. With the popular BluOS Hi-Res streaming platform and playback quality of up to 24-bit/192kHz, the 40 ST offers lightning-fast streaming over the home network and guarantees a listening experience with no loss of quality and almost no delay. Its elegant aluminum housing is not only an aesthetic highlight, but also ensures stable and reliable performance.

BluOS platform: comfort and variety at the highest level with the 40 ST

The integration of the BluOS platform makes the Cyrus 40 ST one of the most versatile streaming devices on the market. The BluOS app allows users to stream millions of songs directly from a variety of music services. Whether on Tidal, Spotify or other platforms - the world of music is literally in the hands of the listener. In addition, internet radio stations, podcasts and even locally stored music from smartphones, tablets or computers can be played anywhere in the house. This seamless integration ensures that music is accessible and available in every room of the house, without complicated settings or additional devices.

High-quality digital performance through tailor-made technologies

As with all Cyrus digital products, bespoke DAC design is at the heart of the 40 ST's engineering. The ESS Sabre ES9039Q2M chip and HyperStream IV Dual DAC technology are at the heart of the 40 ST, delivering exceptional sound quality. Cyrus engineers have fully optimised the entire circuit board layout to ensure each component is perfectly matched. The result is crystal clear, detailed sound that will delight even the most demanding listeners.

The 40 ST is aimed at music lovers who do not want to compromise on sound quality. With its wide frequency range and extremely precise reproduction, every musical nuance is audible - from the subtlest details to powerful bass lines. This technical excellence makes the Cyrus 40 ST one of the best network streamers in its class.

40 Series Cases: Elegance and Functionality

The Cyrus 40 ST is presented in a stylish, black anodized aluminum housing that fits seamlessly into any high-quality audio system. The 5-inch TFT color display with tempered glass and the hidden, capacitive touch controls underline the modern and minimalist design. The controls are only visible when touched, contributing to a simple, uncluttered look. This design is not only aesthetically pleasing, but also functional, as it makes handling the device intuitive and easy.

Power supply upgrade: 40 PSU for maximum stability

For even better sound performance, the 40 ST can be supplemented with the external Cyrus 40 PSU power supply. This power supply provides an extremely stable and noise-free power supply that is digitally controlled internally. By connecting the 40 PSU, the 40 ST is able to achieve its maximum performance by optimally matching the output voltages to the needs of the device. This further improves the already outstanding sound quality.

Roon Ready: Music management made easy

With the Roon Ready function of the Cyrus 40 ST, listening to music becomes a comfortable and well-organized experience. Roon collects all music files, whether they are stored on internal or external hard drives, NAS systems or streaming services such as Tidal or Qobuz, in a clear and easily accessible library. This allows the user not to have to worry about where their music is stored or how it is played - everything is centrally controlled and intuitive to use.

MQA decoding: studio quality in every room

The Cyrus 40 ST features a powerful MQA (Master Quality Authenticated) decoder and audio renderer. This technology enables studio-quality playback of music as originally recorded and released by the artist. This means the listener hears exactly what the artist heard in the studio, without compromising on sound quality. MQA is an end-to-end technology that ensures that even the finest sonic details and nuances are preserved, no matter which room in the house music is played in.

AirPlay 2: Seamless music streaming throughout the house

With AirPlay 2 integration, the Cyrus 40 ST can be integrated into a multi-room setup, where multiple players are synchronized in different rooms. This means music can be played in perfect synchronization from room to room while the user moves freely around the house. Alternatively, different songs can be played in different rooms, all conveniently controlled from an iOS device.

Versatile digital inputs of the 40 ST

For maximum flexibility, the Cyrus 40 ST features optical and coaxial digital inputs. These allow external devices such as CD players or TVs to be connected, so that the sonic benefits of Cyrus' superior DAC circuitry can also be used for these sources. By using the 40 ST's first-class DAC technology, the sound quality is also significantly improved with external audio sources.

The Cyrus 40 ST is not only an outstanding network streamer, but also a central element in any modern, digital hi-fi system. It offers all the functions and technologies that music lovers and audiophiles can expect from a high-end device.
