ST25 Streamer

The ST25 is a cutting-edge digital audio player, meticulously designed in Cambridge, UK. It features an all-new digital audio and streaming platform, a redesigned linear toroidal power supply, a modern user interface, and an updated app.

Exquisite sound quality is achieved through the engineering of a new 6-layer digital audio and streaming platform, which includes a ground plane across the entire board to minimize noise and interference. This platform incorporates the latest Hyperstream iV DAC from ESS in a balanced configuration, with advanced jitter elimination for pristine audio. The sound is further enhanced by a new linear toroidal transformer power supply, driving the internal components with low noise. A switching power supply operates only in standby for peak efficiency.

At the front, the ST25 boasts a new bonded 6.5" high-resolution display, providing clear album artwork and metadata, easily readable from any seat. The comprehensive feature set supports most smartphones, tablets, and popular streaming services. Connecting the ST25 to your home network via Wi-Fi is quick and easy using the ARCAM Radia App. Once connected, you can enjoy seamless playback with Apple AirPlay, Google Cast, Spotify Connect, Tidal Connect, and Roon.

The ARCAM ST25 is the ultimate high-resolution audio upgrade for any Hi-Fi system, particularly when paired with the ARCAM Radia A25. It includes a control link for Radia amplifiers, allowing both components to function as one. Together, they offer an unparalleled listening experience, with isolated components and individual power supplies delivering pure audio bliss.
