New A25+ benefits from all the Radia+ improvements, but also features a new transformer, new cut-glass display for clarity and HDMI eARC.
Arcam switches to Class G amplification for the reference Radia integrated, generating 100W per channel of ultra-low distortion power. This will drive even the most stubborn speakers.
A25+ also adds a USB-C digital in for connection external digital sources - PC, Mac or other.

Product Description
Sept '25 - new and improved A25+ Integrated Amplifier
Arcam's Radia integrated amps are replaced in Sept '25 with their '+' equivalents - A5+, A15+ and A25+. Facelift models, better performance. Plus HDMI eARC connectivity upgrade for A15+ and A25+.
These '+ factor' amps feature upgraded circuitry, next-gen Bluetooth 5.4, enhanced design and lower noise power supply as well as Snapdragon Sound (AptX Lossless) for bit-perfect CD-quality streaming, LE Audio, and Auracast, which allows one-to-many wireless playback without the need for pairing.
The A25+ gets even more upgrades for it's '+' status though - it is the best Radia+ after all. A25+ gains a precision-cut glass front panel that sharpens and brightens the display, complementing the ST25 streaming partner. A25+ also benefits from a new transformer featuring a dedicated winding for the digital and DAC circuitry, double linear regulation in the analogue power supplies, and further power and mains filtering refinements to lower impedance and enhance overall clarity.
The “A” in ARCAM stands for amplification, where our expertise lies. The A25+ is the latest in nearly 50 years of amplifier design and manufacture, dating back to our first product in 1976 - the A&R Cambridge A60 amplifier. Since the launch of the award-winning ARCAM Radia A25+, we haven’t rested. Our engineering team pushed further to create the premium ARCAM A25+, an even better sounding and more versatile integrated amplifier.
With a wide array of analogue inputs, including a meticulously tuned phono stage, and digital inputs including HDMI eARC and USB-C, the A25+ provides an impact for everything from vinyl to TV and streaming.
The A25+ features an enhanced power supply design, new DAC and cutting-edge wireless capabilities straight out of the box. Snapdragon Sound delivers uncompressed digital audio via Bluetooth, while Auracast enables multiple compatible headphones or speakers to share music wirelessly, with no pairing required.
Powered by our 5th generation Class G amplifier design, you can expect the best sound quality and dynamics from what has always been a better sounding and more efficient Class of amplifier.
