Arcam A15+ with Bowers & Wilkins 603 S3 (2025 Model)
It was back in the mid-1970s when Doug Brady introduced the very first amplifier from A&R Cambridge (as the company was then known) — the A60. This model featured prominently in many of our magazine advertisements and helped establish our reputation in British hi-fi. Since then, Arcam has produced many highly regarded amplifiers. The Arcam A15 continued that legacy with great success, earning a reputation for performance and reliability. Naturally, expectations are high for its successor, the Arcam A15+, which is set to carry the torch forward.

Signature Arcam Sound, With More Power
Like the more affordable A5, the A15+ retains Arcam’s signature full-bodied, smooth sound — but with added power. It delivers greater clarity, scale, and precision, making it a perfect choice for pairing with tower speakers, filling larger rooms, and enjoying music at higher volumes without compromising quality.
Built on Decades of Expertise
The “A” in ARCAM stands for amplification — the foundation of everything we do. The A15+ represents the latest chapter in almost 50 years of amplifier innovation, beginning with the launch of our first product in 1976, the A&R Cambridge A60. Following the award-winning ARCAM Radia A15, our engineers have gone further still, creating a more powerful, better-sounding, and more versatile integrated amplifier in the A15+.
Impressive Connectivity
The A15+ offers a wide range of connectivity options, including analogue inputs and a meticulously tuned phono stage for vinyl lovers. It also features modern digital inputs, including HDMI eARC, making it ideal for enhancing both music and TV audio with impact and precision.
Wireless Audio Without Compromise
Equipped with an upgraded power supply and advanced wireless capabilities, the A15+ is ready to perform straight out of the box. Snapdragon Sound delivers uncompressed Bluetooth audio, while Auracast allows multiple compatible headphones or speakers to stream music wirelessly — with no pairing required.
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.
