Arcam ST25: High-end network audio player

The Arcam ST25 represents the pinnacle of Arcam's network audio player offerings. It supports streaming audio from all leading services such as Tidal, Qobuz, Spotify, Napster, and Deezer, in addition to accessing local network storage, all while keeping jitter levels under 20 picoseconds. Constructed to exceptional standards, the ST25 features a design that is consistent with the rest of the product line.

At the front, the Arcam ST25 features a new 6.5-inch high-resolution display that displays album art and metadata for easy viewing from the comfort of your favourite seat. For playback, the full suite of features supports most smartphones and tablets, as well as popular streaming services. Connecting the ST25 to your home network via Wi-Fi is quick and easy using our ARCAM Radia app. Once connected, enjoy instant playback via Apple Airplay, Google Chromecast, Spotify Connect, Tidal Connect and Roon. The Radia app includes Amazon Music, Qobuz, Global Internet Radio and Podcasts.

The player is equipped with a full set of network interfaces: Ethernet, USB and wireless Wi-Fi. Also on the rear panel of the device there are unbalanced analog outputs, coaxial and optical digital outputs, which provides optimal flexibility for connecting the Arcam ST25 to various systems. This model also contains four digital inputs, which allows it to be used as a DAC for external signal sources.

The Arcam ST25’s superb audio quality has been achieved through the clever design of a new 6-layer digital audio and streaming platform, which includes a ground plane across the board to direct noise and interference away from sensitive audio components. These components include the latest ESS Hyperstream iV DAC topology in a balanced configuration with improved jitter elimination. The audio quality is further improved by a new power supply design, with a linear toroidal transformer that keeps all internal workings running with less noise, and a switching power supply that only operates at maximum efficiency in standby mode.

Overall, the unit offers the good versatility expected of a new generation of networked audio products. The Arcam ST25 is a great partner for all Arcam amplifiers, but can be installed in any stereo system to extend the networking capabilities of your audio setup.
