Its newly developed six-layer digital audio platform incorporates a dedicated ground plane to help isolate sensitive circuitry from electrical noise, while the latest ESS Hyperstream IV DAC topology operates in a balanced configuration with advanced jitter elimination for precise, detailed music reproduction. A low-noise linear toroidal power supply, 6.5-inch bonded color display and support for music up to 32-bit/384kHz and DSD256 position the ST25 as ARCAM's flagship standalone streaming source. Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready, Apple AirPlay and Google Cast provide extensive streaming flexibility, while UPnP and USB media support accommodate locally stored music libraries. A dedicated control link also allows particularly elegant integration with compatible ARCAM Radia amplifiers. Highlights & Benefits 32-Bit/384kHz High-Resolution Streaming — Supports high-resolution PCM playback up to 32-bit/384kHz along with DSD256 for compatible music libraries and sources. ESS Hyperstream IV DAC Architecture — ARCAM's latest digital conversion platform uses a balanced ESS topology with advanced jitter elimination for low noise, precise timing and excellent musical detail. Major Streaming Services Built In — Spotify Connect, TIDAL Connect, Qobuz Connect, Roon Ready, Apple AirPlay and Google Cast provide extensive playback flexibility. 6.5-Inch High-Resolution Display — The bonded front-panel color display clearly presents album artwork, track information and system status from across the listening room. Dedicated Linear Power Supply — A low-noise toroidal transformer powers the ST25 during normal operation, with a separate switching supply reserved for efficient standby operation. Technology & Design Six-Layer Digital Audio Platform — ARCAM developed a new six-layer streaming board with a ground plane extending across the entire board to help keep noise and interference away from sensitive audio components. Balanced ESS Hyperstream IV Conversion — The latest ESS Hyperstream IV DAC architecture is implemented in a balanced configuration with advanced jitter elimination, helping preserve low-level detail, timing accuracy and stereo imaging. Linear Toroidal Power Supply — Unlike many compact network players that rely entirely on switch-mode power, the ST25 uses a newly designed linear toroidal power supply for its internal operation to minimize electrical noise. ARCAM Radia System Integration — A supplied control cable allows compatible Radia amplifiers and the ST25 to operate together more conveniently while maintaining the sonic advantages of separate streamer and amplifier chassis with independent power supplies. FAQ — Arcam ST25 Does the ARCAM ST25 have a built-in DAC? Yes. The ST25 incorporates ARCAM's latest ESS Hyperstream IV DAC topology in a balanced configuration with advanced jitter elimination, allowing it to connect directly to an amplifier through its stereo analog RCA output. Which streaming services does the ST25 support? The ST25 supports Spotify Connect, TIDAL Connect, Qobuz Connect and Roon Ready playback, along with Apple AirPlay and Google Cast. The ARCAM Radia platform also provides access to internet radio, podcasts, UPnP and USB media playback. Can the ST25 be used with an external DAC? Yes. The ST25 provides both coaxial and optical digital outputs, allowing it to function as a dedicated network transport with a compatible external DAC or digital-capable amplifier. What amplifier is a natural partner for the ST25? The ST25 was designed as a particularly strong companion for ARCAM's Radia integrated amplifiers. Its dedicated control connection enables convenient integration while keeping the streamer and amplifier in separate chassis with independent power supplies.
