Streamer. Perfect for the Aficionado – The ARCAM ST25 is the ideal music streaming source for any Hi-Fi System and the ARCAM Radia A25.

The ST25 is an all-new digital audio player expertly crafted in Cambridge, UK. It is more than a successor to the award winning ARCAM ST60 streamer, with an all-new digital audio and streaming platform, new linear toroidal power supply design, new user interface and new app.

Exquisite sound quality has been achieved through thoughtful engineering of a new 6-layer digital audio and streaming platform which includes a ground plane through the entire board to wick noise and interference away from the sensitive audio components. These components include the latest Hyperstream iV DAC topology from ESS, in a balanced configuration with advanced Jitter elimination. Sound quality is enhanced further with a new linear toroidal transformer power supply design that drives the entirety of the internal operation with lower noise, and a switching supply that only operates for peak efficiency when in standby.

Up front, the ST25 features a new, bonded 6.5″ high-resolution display to show album artwork and metadata which is clearly legible from the comfort of your preferred armchair. For playback, an inclusive feature set supports most smart phones and tablets, as well as popular streaming services. Connecting the ST25 to your home network with Wi-Fi is quick and straightforward with our ARCAM Radia App. Once connected, enjoy instant playback using Apple Airplay, Google Chromecast, Spotify Connect, Tidal Connect, and Roon. The ARCAM Radia app includes Amazon Music, Qobuz, Global Internet Radio and Podcasts.

The ARCAM ST25 is the ultimate high resolution audio upgrade for any Hi-Fi system, especially the ARCAM Radia A25. It includes a control link for ARCAM Radia amplifiers, allowing the 2 components to act as one from your device. Sonically, this combination offers pure audio paradise, thanks to the benefits of isolated components with individual power supplies.
