The Arcam Radia ST25 is the high-resolution audio upgrade for any Hi-Fi system. It includes a control link for ARCAM Radia amplifiers, allowing the two components to act as one from the device. In terms of sound, this combination offers pure audio heaven, thanks to the benefits of isolated components with individual power supplies.
Exquisite sound quality has been achieved through careful design of a new 6-layer digital audio and streaming platform that includes a ground plane across the entire board to keep noise and interference away from sensitive audio components. These components include ESS' latest Hyperstream iV DAC topology, in a balanced configuration with advanced jitter elimination.
Sound quality is further enhanced with a new linear toroidal transformer power supply design that drives the entire internal operation with less noise and a switching power supply that only operates for maximum efficiency when in standby mode.
Up front, the ST25 network audio player features a new 6.5" high-resolution screen to display album art and metadata, which can be read clearly from the comfort of your favourite armchair. For playback, an included feature set is compatible with most smartphones and tablets, as well as popular streaming services.
Connecting the ST25 to your Wi-Fi home network is quick and easy with our ARCAM Radia app. Once connected, enjoy instant playback with Apple Airplay, Google Cast, Spotify Connect, Tidal Connect and Roon.
