Arcam ST25 Streamer Review: A New Benchmark in High-Resolution Audio Streaming
Our Arcam ST25 Streamer Review highlights a breakthrough in high-resolution streaming that marries cutting-edge engineering with effortless usability. Designed in Cambridge and tailored for the discerning listener, the ST25 brings studio-grade audio, robust connectivity and an intuitive interface to any Hi-Fi system - especially when paired with the ARCAM Radia A25 integrated amplifier.

Precision Engineering: Inside the ST25
The ST25's all-new 6-layer digital audio and streaming platform is a testament to Arcam's commitment to noise control. A continuous ground plane isolates sensitive components, while the ESS Hyperstream iV DAC topology operates in a balanced configuration with advanced jitter elimination. The outcome is an ultra-clean signal path that preserves every nuance from the original recording - from the subtlest ambience to the most explosive crescendos.
Power Supply & Noise Rejection
At the heart of the ST25 lies a newly designed linear toroidal transformer power supply that delivers regulated, low-noise energy across the entire board. By relegating a high-efficiency switching supply to standby duties, Arcam ensures the streamer remains quiescent when inactive and springs to life with maximum efficiency during playback. The audible benefits include tighter bass control, exceptional midrange clarity and a pitch-black background that lets the music breathe.
High-Resolution Display & User Interface
Front and centre, a bonded 6.5-inch high-resolution display showcases album artwork and metadata in striking detail. Legible from your favourite listening spot, the screen elevates the interaction by providing immediate visual feedback. Browsing playlists, Internet Radio stations and podcast libraries becomes a breeze, making digital streaming feel as engaging as flicking through vinyl sleeve art.

Connectivity & Streaming Features
Whether you're immersed in Apple AirPlay, Google Chromecast, Spotify Connect or Tidal Connect, the ST25 handles every major streaming protocol with aplomb. Setup is effortless via the ARCAM Radia App, which also unlocks Roon Ready compatibility (post-launch), Internet Radio and Podcast presets. Physical connections include coaxial and optical digital outputs, alongside analogue RCA outputs and a rear-panel USB-A port for local media. This versatility ensures seamless integration with virtually any amplifier or preamplifier.

Sonic Signature & Performance
In blind listening sessions, the ST25 stood out for its poise and control. Treble remained clean and extended without harshness, mids offered a warm yet detailed portrayal of vocals and instruments, and bass was taut and articulate. The streamer's soundstage is impressively wide, with precise imaging that places each element with pinpoint accuracy. Whether revisiting classic jazz recordings or exploring modern high-res files, the ST25 delivers a captivating performance.
Who Should Consider the ST25?
The ST25 is perfect for audiophiles seeking a dedicated digital source to replace ageing CD transports or entry-level streamers. It shines in setups that demand high-resolution fidelity - notably in combination with the ARCAM Radia A25 integrated amplifier, where its control link ensures both units operate in seamless harmony. If you crave a future-proof streaming solution with top-tier engineering, the ST25 deserves serious consideration.
