Modern Control Center for Digital Audio
The Arcam Radia ST25 serves as a powerful network player and streamer that integrates digital music content into existing hi-fi systems with the highest fidelity.
Excellent Sound Fidelity through High-Res Support
The device processes signals up to 32 bit / 768 kHz as well as native DSD1024. These technical capabilities enable lossless playback and exceptional precision, closely approaching the original recordings.
Unlimited Streaming and Format Variety
With access to over 100 million songs, the ST25 offers an almost endless selection of content. Leading services such as Tidal and Spotify are supported, as are internet radio, podcasts, and audiobooks. Thanks to compatibility with Apple AirPlay, Google Chromecast, and Roon-ready certification, the streamer can be seamlessly integrated into various multiroom and network environments.
High-Resolution Display and Intuitive Control
A prominent feature is the 6.5-inch color display, which clearly shows album covers and track information. Operation can be done directly via the buttons on the device, the included remote control, or conveniently via the ARCAM Radia App for Android and iOS.
High-Quality Workmanship "Made in UK"
The elegant black streamer represents British engineering. With its solid casing and the clean lines of the Radia series, it fits both aesthetically and technically into demanding audio setups.
