Arcam A15+ with KEF R3 META Speakers (2025 Model)
Couldn't load pickup availability
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.
KEF R3 META Speakers
The KEF R3 Meta redefines bookshelf speakers’ performance. Sharing the same drivers as the range-topping R11 Meta, the R3 Meta is a true three-way design. It has a 12th generation Uni-Q® driver array with MAT™ and a powerful 6.5” hybrid aluminium bass driver that pushes performance to wonderfully new extremes.
The R Series is a direct beneficiary of the technological innovations developed for The Reference, the class-leading series that continually set the benchmark for loudspeakers and sound reproduction. Combining with bespoke technologies, the R Series delivers an exceptional acoustic performance. The revolutionary Metamaterial Absorption Technology1 (MATTM) has been incorporated into the latest iteration of the R Series, and the 12th generation Uni-Q® driver array has been refined to maximise the impact of this technological advance and ensure the best possible performance.
Features
- Metamaterial Absorption Technology (MATTM) eliminates 99% of high-frequency distortion for pure, natural sound
- Bespoke 12th generation Uni-Q with MAT driver array for exceptional acoustic accuracy
- Refined tweeter gap damper tames resonances for improved detail
- Flexible Decoupling Chassis prevents unwanted vibrations for better clarity
- Enhanced crossover design and fine-tuned the signal path for pristine, clean sound
Superior KEF sound
A bespoke 12th generation Uni-Q driver array with MAT is found in all seven models of the R Series and delivers an incredibly detailed performance. It’s the result of decades of accumulated in-house knowledge and the application of cutting-edge simulation and analysis tools. The developments are many and all play a part in R Series’ exceptional performance.

The result is an exceptional seven-model range of loudspeakers, engineered to deliver with exquisite detail and incredible insight. Whether your taste lies with traditional two-channel HiFi, multi-channel home theatre or both, the R Series reveals levels of detail that must be heard to be believed.
Deep, agile bass
Bass is a vital element of performance, and the low-frequency drivers of R Series have been engineered with acute care and precision. They are built using a two-part structure, where a shallow concave aluminium skin sits atop a paper cone. This stiffness combined with the cone’s unique geometry reduces unwanted resonances and delivers the pistonic movement that makes these drivers time so well. The drivers’ magnet system creates a broad, uniform magnetic field, while the suspension reduces harmonic distortion for a clean, precise sound. The result is exceptionally deep and agile bass that reveals every last bit of detail and punch available in the deep.
