Arcam ST25

Radia active

Cambridgeshire’s Arcam is adding three new models to its recently released Radia Series.

The ST25 is the brand’s range-topping digital audio player that builds upon its ST60 predecessor with an all new digital audio platform that’s based on the latest Hyperstream IV DAC topology from ESS. It also gets a newly designed linear toroidal power supply and upgraded user interface with large, high-res display.

Inside its ground plane spans the entire board to ‘wick’ noise and interference away from its sensitive audio components, while streaming support is on offer for Apple Airplay, Google Chromecast, Spotify Connect, Tidal Connect, and Roon.

Joining this are the SA45 and SA35 all-in-one systems that come loaded with Class G amplification and hi-res music streaming, mirroring the ST25’s tech.

Equipped with a switchable moving-magnet/moving-coil phono stage, alongside HDMI ARC support and two-way aptX Adaptive Bluetooth (for music streaming or headphones listening) plus subwoofer outputs, they have all bases covered, from vinyl playback to TV integration.

The SA45 boasts fully balanced digital and analogue audio paths, a redesigned power supply and 5th generation Class G amplification with 180W on offer per channel into 8 ohms (300W / 4 ohms). An 8.8” hi-res display is there for control while Dirac Live is incorporated for room correction.
