Arcam A25+ with Bowers & Wilkins 603 S3 (2025 Model)
It was way back in the mid-1970s when Doug Brady showcased the first amplifier from A&R Cambridge (as the company was then known) — the A60, which featured in many of our magazine adverts. The Arcam A25 continued that legacy with great success, earning a reputation for performance and reliability. Naturally, expectations are high for its successor, the Arcam A25+, which is set to carry the torch forward.

The Best of the Radia+ Range
The ARCAM A25+ is the best sounding and most versatile of Arcam’s Radia+ integrated amplifiers. The A25+ is the latest in nearly 50 years of amplifier design and manufacture, dating back to their first product in 1976 — the A&R Cambridge A60 amplifier.
Continuous Innovation
Since the launch of the award-winning ARCAM Radia A25, it is clear they haven’t rested. Their engineering team pushed further to create the premium ARCAM A25+, an even better sounding and more versatile integrated amplifier.
Extensive Connectivity
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 impactful sound for everything from vinyl to TV and streaming.
Cutting-Edge Performance
The A25+ features an enhanced power supply design, a 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.
Superior Amplification Technology
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.
603 S3 Floorstanding Speakers
The Bowers & Wilkins 603 S3 is the largest loudspeaker in the 600 Series and is ideal for larger rooms and home theatres. It combines their new Titanium Dome™ tweeter—which offers both clarity of sound, as well as excellent high frequency dispersion—with Continuum cone technology for a truly audiophile experience.
Layered, beautiful details
The 603 S3's Titanium Dome tweeter delivers smooth and refined high-frequency reproduction, providing an accurate and immersive insight into your favourite music. 603 S3 boasts a new design that dramatically improves the materials used in its tweeter grille mesh, first developed for our revered Signature models. The Titanium Dome tweeters provide exceptional resolution and realism.
Precision and transparency
The Continuum cone avoids the abrupt vocal transitions that can impair conventional drive units. With 603 S3, experience a more open and neutral performance—voices are delivered with precision and transparency.
Upgraded Performance
Based on the set of speaker terminals we introduced in our 700 Series, the 603 S3's improved design offers a cleaner signal-path between your amplifier and loudspeakers.
