Arcam A5+ with Bowers & Wilkins 603 S3 (2025 Model)
It was back in the mid-1970s when Doug Brady introduced the very first amplifier from Arcam – then known as A&R Cambridge – the A60. This iconic model featured prominently in many of our magazine advertisements at the time. The Arcam A5 continued that legacy with great success, earning a reputation for performance and reliability. Naturally, expectations are high for its successor, the Arcam A5+, which is set to carry the torch forward.

Nearly 50 Years of Amplification Expertise
The ARCAM A5+ is designed to bring people together through shared listening experiences with family and friends. The “A” in ARCAM stands for amplification – the foundation of everything we do. This latest model represents the culmination of almost five decades of amplifier innovation, dating back to our very first product in 1976: the A&R Cambridge A60. Building on the award-winning ARCAM Radia A5, our engineers have continued to push the boundaries, resulting in an amplifier that’s even more capable and refined.
Engineered for Today’s Listener
At the heart of the A5+ is a newly enhanced power supply and state-of-the-art wireless functionality. With Snapdragon Sound, it delivers lossless digital audio via Bluetooth, while Auracast allows multiple compatible headphones or speakers to stream audio simultaneously – no pairing required. This forward-thinking technology ensures effortless connectivity, whether you're enjoying a personal session or sharing your music with others.
Versatility Meets Precision
The A5+ offers a wide selection of digital and analogue inputs, including a meticulously tuned phono stage for vinyl enthusiasts. Whether you're streaming music, spinning records, or connecting traditional hi-fi components, the A5+ guarantees superb sound quality across all sources. It's a modern integrated amplifier that stays true to Arcam’s longstanding dedication to precision audio and elegant design.
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.
