Arcam Radia Streaming Flagships

The renowned British brand Arcam has expanded its Radia series with three new streaming flagships. At the High End trade fair in Munich, the Harman Luxury Audio Group presented the three new components that enrich the series.

The new additions include the Arcam Radia ST25, a powerful network player, as well as the Arcam Radia SA35 and Arcam Radia SA45 streaming amplifiers. These models offer impressive sound quality thanks to the integration of Class G amplifiers and high-resolution music streaming, all in a single enclosure.

With the introduction of these new devices, the Radia series grows to a total of eight models, including amplifiers, disc players and music streamers. The Arcam Radia ST25 builds on the success of its predecessor, the award-winning ST60, and sets new standards in performance and technology.

The Arcam Radia SA35 and Arcam Radia SA45 all-in-one systems represent the next evolution of the popular Arcam range. Thanks to the latest 5th generation Class G amplification and an advanced streaming platform, they offer an outstanding listening and user experience.

The ST25 is the top of the range Arcam music streamer. It embodies the unmistakable style of the Radia series and takes a new approach on the inside. Building on the success of the ST60, the ST25 features a host of new technologies, including a new digital audio and streaming platform, a redesigned linear toroidal power supply and an improved user interface with a large, high-resolution color display.

Under the hood, the ST25 presents a carefully considered layout, including a ground plane that spans the entire board, effectively diverting noise and interference away from sensitive audio components.

Equipped with the latest Hyperstream IV DAC topology from ESS, the ST25 uses a new linear toroidal transformer power supply that helps to reduce noise levels throughout the unit. On the front, the ST25 features a high-resolution 6.5-inch display. It connects seamlessly to the Wi-Fi network via the Arcam Radia setup app and offers playback options via Apple Airplay, Google Chromecast, Spotify Connect, Tidal Connect and Roon.

The ST25 also features a control connection for Arcam Radia amplifiers, allowing the two components to amplify the sound thanks to the benefits of isolated components with individual power supplies. The ST25 is an outstanding choice for audiophiles and the clear choice as a partner for the integrated A25.

Streaming powerhouses

The SA35 and SA45 models integrate Arcam’s latest streaming platform, which mirrors the technology of the ST25, and combine it with the Cambridge-based manufacturer’s fifth generation of Class G amplifiers. The result is two exceptional all-in-one systems. In combination with the appropriate loudspeakers, music fans receive a complete hi-fi system that guarantees a first-class sound experience.

The SA35 and SA45 models are suitable for both classic and modern audio configurations. Equipped with a switchable MC/MM (Moving Coil/Moving Magnet) phono stage, they integrate seamlessly with turntables and offer an authentic vinyl experience. In addition, HDMI ARC support simplifies cable connections and device control for users connecting compatible TVs. For wireless devices, the two-way aptX Adaptive Bluetooth module ensures exceptional sound quality whether music is streamed to the system or enjoyed through Bluetooth headphones.

Inspired by the A49, a former two-channel juggernaut, the SA45 features fully balanced digital and analog audio paths, a redesigned power supply and Arcam’s fifth-generation Class G amplifier, which delivers a whopping 180 watts per channel into 8 ohms and 300 watts into 4 ohms. With a high-resolution 8.8-inch display, Bluetooth 5.2 connectivity, subwoofer outputs and Dirac Live Room Correction, the SA45 is a true piece of hi-fi.

The SA35 offers 120 watts per channel into 8 ohms and 220 watts into 4 ohms, has a high-resolution 6.5-inch display and matches the SA45 in terms of streaming functions and Dirac readiness. Both models come with a measurement microphone and remote control to help with room calibration.
