Streaming, Refined to the Radia Standard
The ARCAM ST5 brings dedicated network streaming to the celebrated Radia series — a slim, purposeful source component engineered in Britain to carry music from every major service with genuine high-fidelity conviction. Where lifestyle products treat streaming as a convenience, the ARCAM ST5 treats streaming as the performance itself: a single, considered instrument for the digital age, styled to sit gracefully beneath a Radia amplifier and disappear into the pleasure of the evening’s programme.
Every Service, One Elegant Source
Spotify Connect, Tidal Connect and Qobuz Connect are built directly into the ARCAM ST5, so playback begins from the familiar app in your hand and hands over to the streamer for the critical work. Apple AirPlay and Google Cast extend that ease to virtually any phone or tablet in the household, while Roon Ready certification welcomes the most ambitious digital libraries with full-resolution grace. Internet radio, podcasts and music stored on USB drives or a home server are all gathered under the ARCAM Radia app — one interface for an entire listening life. Few network streamer designs at any level offer a more complete or more considered set of ways to reach your music.
Conversion That Honours the Recording
Every stream passing through the ARCAM ST5 is rendered by an ESS Sabre digital-to-analogue converter with time-domain jitter elimination — technology chosen for the ability to strip digital timing errors from the signal before they can blur an image or harden a string tone. High-resolution files play natively to 24-bit/192kHz, with DSD and MQA material handled with equal assurance. The result is the sound that has defined the finest ARCAM digital products for decades: spacious, tonally truthful, and free of the glassy signature lesser conversion leaves behind. This is a music streamer built for long evenings rather than quick demonstrations.
A Natural Partner for Radia Amplification
A dedicated control connection — cable supplied — allows the ARCAM ST5 to synchronise with the ARCAM A5+ and A15+ integrated amplifiers, so streamer and amplifier answer to a single app with unified volume and input control. The pairing behaves like a one-box system yet preserves everything separates do best: isolated chassis, individual power supplies, and the quieter, more dimensional presentation that follows. For anyone building a Radia system, the ARCAM ST5 is the streaming half of a genuinely symbiotic design.
Quietly Assured British Design
The slim chassis measures barely a hand’s height, finished with the restrained geometry that distinguishes the whole Radia range, and fronted by a clear display that can be dimmed or extinguished entirely once the music starts. A full remote control is included, and packaging is entirely plastic-free — a small courtesy, characteristic of a company that has been thinking carefully about hi-fi since 1976. As a network audio streamer for an elegant living space, the ARCAM ST5 asks for very little room and even less attention.
Effortless to Live With
Setup takes minutes: connect to the network by Ethernet for absolute stability, or over dual-band Wi-Fi guided by the ARCAM Radia app. Analogue outputs feed any amplifier directly, while coaxial and optical digital outputs invite an outboard DAC for those pursuing an audiophile music streamer as a pure transport. Selectable digital filters allow the final voicing to be tailored by ear. To hear what a truly resolved hifi streamer brings to a system — and how naturally the ARCAM ST5 completes a Radia pairing — we would be delighted to arrange a private audition at Audio Lounge on Wigmore Street.

About ARCAM
Founded in Cambridge in 1976, ARCAM has spent five decades pursuing sound quality with quiet British determination. The company’s digital pedigree is unmatched at the accessible end of high-end audio: the ARCAM Delta 70 CD player arrived in 1986, followed in 1988 by the Delta Black Box — the world’s first separate DAC, a category ARCAM effectively invented. Today, as part of the HARMAN Luxury Audio family, ARCAM continues that lineage through the Radia series, matching contemporary streaming convenience to engineering values that have never wavered.
