Arcam Radia A25 Plus - Integrated Amplifier

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.
