Arcam A25+ with KEF R3 META Speakers (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.
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.
