Arcam A25+ with Bowers & Wilkins 607 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.
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.
The Bowers & Wilkins 607 S3
With its compact size the Bowers & Wilkins 607 S3 2-Way Bookshelf Speaker produces a clean and precise sound using a 1" decoupled double dome titanium tweeter and 5" continuum cone midrange/bass driver. Sound that offers smooth high frequencies and precision voice and instrument reproduction. Even at its smaller size, the pair of speakers are capable of filling a small to medium sized room.
Features
- Compact form with powerful and scaled sound.
- New Titanium Dome tweeter for exceptional resolution and smooth high-frequency reproduction.
- Acoustically transparent tweeter grille mesh for enhanced realism and detail.
- Continuum bass/midrange cone for accuracy and transparency.
- Upgraded speaker terminals for improved signal path.
Layered, beautiful details
The new 607 S3 introduces the Titanium Dome tweeter, which combines exceptional resolution and insight with smooth, refined high-frequency reproduction. The result? An accurate and immersive insight into your favourite music.
Precision and transparency
Thanks to its composite construction, the Continuum cone avoids the abrupt transitions in behavior that can impair the performance of a conventional drive unit. With 607 S3, experience a more open, neutral performance that delivers voices and instruments with precision and transparency.
Upgraded speaker terminals
Derived from the speaker terminals recently introduced in our 700 Series range, the speaker terminals on the new 607 S3 feature an improved layout and a cleaner signal path between your amplifier and your loudspeakers.
You can also take your listening experience to new heights by placing these speakers on the Bowers & Wilkins FS-600 S3 Speaker Stands (sold separately) to reduce vibrations and improve the soundstage.
