Building upon the predecessor's legacy, the ST60, the ST25 embodies the distinctive style of the Radia Series. Under the hood, it applies a host of new technologies, including a new digital audio and streaming platform, a redesigned linear toroidal power supply, and an upgraded user interface, including a large, high-resolution, full-colour display.

The manufacturer says the ST25 features a “meticulously engineered” layout, including a ground plane that spans the entire board, effectively wicking noise and interference away from the sensitive audio components. It also benefits from the latest Hyperstream IV DAC topology from ESS and a new linear toroidal transformer power supply, which helps maintain lower noise levels throughout the device. Meanwhile, upfront, the ST25 features a 6.5-inch high-resolution display.

Hook up the ST25 to your Wi-Fi network using the ARCAM Radia set-up app, and you will be offered playback options through Apple Airplay, Google Chromecast, Spotify Connect, TIDAL Connect, and Roon.

The ST25 also includes a control link for Arcam Radia amplifiers, allowing the two components to “boost sonics due to the benefits of isolated components with individual power supplies”.


The SA35 and SA45 models borrow Arcam's latest streaming platform from the ST25 and combine it with the Cambridge firm's 5th generation G Class amplification to create a new pair of all-in-one, just add speakers systems.
