The Stream-XR is our best performing and feature-rich network streaming DAC that complements the high-end XR series, offering uncompromising sound quality. Compared to the Classic STREAM, it comes with a high-resolution display, capacitive touch buttons and includes two presets for instant access to your favourite radio or music service.

The Stream-XR benefits from the onboard award winning 2nd generation QXR DAC, which offers two digital inputs, that brings additional flexible digital connectivity to any system. With the high quality components expected from any product in the XR series, the Stream-XR extracts more content and emotions from any musical performance. Additionally, it is also compatible with our intelligent external power supply – the PSU-XR, which takes the performance to another level.

Utilising the renowned BluOS streaming platform, the Stream-XR comes fully packaged with all the features and benefits you would expect from a modern streamer. The ongoing development and support for BluOS is secured by a third party, providing a guarantee that the BluOS software will be maintained and developed well into the future, should new streaming options become available.

Using advanced technologies, the Stream-XR can wirelessly transmit lossless music up to 24-bit/192kHz at lightning-fast speeds across your home network with no lag and zero loss in sound quality, and also allows you to connect with your own digital music library, all via the intuitive BluOS app.

Available for iOS, Android, Kindle, Mac or PC computers, the app allows music playback from all the major audio streaming services such as Tidal, Qobuz, Deezer, Spotify and dozens of others as well as Roon (pending), Airplay2 and also allows for MQA decoding.

If it is uncompromising sound quality, coupled with the convenience and ease of use of the BluOS streaming platform that you are looking for – give the Stream-XR a listen!

The DAC output stage of the Stream-XR features the 2nd generation of our award-winning QXR DAC, which includes a high-speed analogue buffer stage. The QXR DAC design is based on the ESS ES9038Q2M chipset, which has had every component analysed by our engineering team, coupled with the layout being fully optimised to tune the DAC to achieve the highest possible performance. The result is a DAC that reconstructs the analogue signal with incredible accuracy and precision, revealing layers and depth that will have you listening back through your complete music collection.

Roon brings all your music together, so you don’t have to worry about where it’s stored, what format it’s in, or where you stream it from. Roon supports music files stored on internal and external hard drives and NAS, your iTunes library, live radio stations and streamed content from Tidal and Qobuz.


With Airplay2 on the Stream-XR, you can connect multiple players around the house and have them communicate with each other through AirPlay. Listen to your music in perfect sync as you walk room-to-room, or play different songs in different rooms, and control everything on your iOS device. You can even say the song you want to list to and where and let Siri take control of your music experience.

Built into the Stream-XR is a revolutionary end-to-end (studiospeaker) technology known as Master Quality Authenticated (MQA), which captures and delivers master quality audio from your favourite artists’ recording sessions to any room in your home. The Stream-XR includes a powerful decoder and audio renderer for the MQA system, allowing you to hear exactly what the artist recorded and approved in the studio.

The Stream-XR includes a port for the PSU-XR power supply. Thirty years ago, Cyrus broke new ground with the introduction of the PSX-R, the first ever regulated power supply upgrade that automatically adapted to match perfectly the power requirements of any connected product. The PSU-XR raises the bar by sourcing no less than five independent regulated supplies in a single box. For the Stream-XR, this takes over the DAC to provide a cleaner, more stable supply and the network card where the superior supply gives greater clock stability.

Using BluOS

The Stream-XR does not only provide the ability to stream your favourite music from a large selection of music services or internet radio direct from the BluOS app, you can also easily connect to your personal music collection via your home network.

The ease of using the BluOS platform is one of the key benefits of the Stream-XR, but if you do find yourself needing some assistance, BluOS provide a number of article covering different subjects on their support pages.

The Stream-XR with integrated top-class DAC offers sophisticated functionality and top sound.

The Stream-XR is a logical addition to any existing Cyrus system, especially when dealing with the newer XR models. It’s positive to see that Cyrus Audio didn’t just provide any streamer. By opting for BluOS and integrating it with their own QXR DAC solution, they have built a streamer that performs well and fits into a broader narrative.

The Cyrus Duo [Stream-XR + i9-XR] was a marvel of airy and dynamically fast sound, which typically characterises electronics with low feedback. Yes, the duo was truly a lively and fresh breeze compared to the (cheaper) streaming amplifiers we simultaneously tested.

In summary, the Cyrus streamer as a standalone source offers the highest sound quality for a device of this kind. I would not be surprised if a significant number of end-users choose to stick with it for longer. And when considering an upgrade, a few moments spent listening to it with the PSU-XR connected will dispel any doubts.

Audio Video (Polish)

[Stream-XR] is quite a successful proposition in its segment. It provides a well-balanced and coherent sound with a good mix of precision, fullness and colourfulness, excellent imaging, and is clearly devoid of weak points. The functionality based on the proven BluOS platform, compatibility with Roon [pending Roon certification], the ability to work with a USB drive, and two digital inputs check off the mandatory list, with the potential advantage of an upgrade with the PSU-XR power supply.

With significantly more substance and finely delineated nuances, the Cyrus Stream-XR was able to distinguish itself clearly from the truly not bad Bluesound Node. Although both are based on BluOS, the Node, priced at under 600 Swiss francs, operates in a completely different league. However, it once again demonstrated that even in the digital domain, where it ostensibly comes down to just zeros and ones in the correct sequence, higher investments can lead to better sonic results.
