The ST25 is Arcam's new streamer, which implements the new digital audio streaming platform, a new linear power supply stage with a toroidal transformer, a new user interface, and a new App.

Sound quality benefits from a new 6-layer digital audio and streaming circuit layout, with a complete ground plane to keep noise and interference away from the most sensitive audio components.

These components include the latest ESS Hyperstream IV DAC topology in a balanced configuration to eliminate jitter.

Sound quality is further enhanced by the new power supply design that uses a linear toroidal transformer. On the front, the Arcam ST25 features a new high-resolution 6.5" display for showing album artwork and metadata. Connecting the SA35 to your home network via Wi-Fi is quick and easy thanks to the ARCAM Radia App. Once on the network, you can enjoy instant playback from the most popular streaming services via Apple Airplay, Google Cast, Spotify Connect, Tidal Connect, and Roon.

The ARCAM ST25 can be considered the ideal streaming upgrade for any Hi-Fi system, particularly, to stay within the ARCAM family, for the Radia A25 amplifier. In this case, the two devices connected together can interact with a single remote control or a single App. From a sound perspective, this combination offers maximum performance, thanks to the advantage of having two completely separate power stages.
