The ideal amp for all your music

With a heritage that stretches back to 1976, Arcam’s amplifiers have always been amongst the best in their class for balancing sound with features.

It was way back in the mid 1970s when Doug Brady showcased the first amplifier from Arcam (A&R Cambridge as the company was called then) the A60 which featured in many of our magazine adverts.

Sleek new style

As part of Arcam’s Radia series, the A25 looks slicker than any previous Arcam amp. With just two dials and subtle illumination, the amp strikes the perfect balance in catching the eye without distracting from the sound. The all-aluminium casing includes the volume and input dials, giving a high quality look and feel. A compact remote control is also included.

Talented in every area

The Arcam A25 features the company’s unique Class G amplifier for incredibly powerful and efficient sound. It’s also Arcam’s best-connected amplifier, with a wide range of inputs including a USB-C interface that’s exclusive to the A25 model. An all-aluminium casing, with backlit aluminium dials gives this amp the luxury aesthetic to match its premium sound quality.

Perfectly balanced sound

With new components and materials, the sound quality is cleaner and more precise, while still retaining the smooth and richly detailed sonic signature that has made Arcam so popular over the past decades.

A treat for your turntable

Much more than just a box-ticking exercise, the Arcam A25’s built-in phono stage makes a top quality connection for your turntable. Suited to turntables with MM (Moving Magnet) cartridges, the high spec phono stage draws a deep seam of information from your vinyl, letting you hear subtle details from the music that might previously have been missed.

Unique to the A25, this Arcam amplifier features a USB-C input, allowing you to connect a laptop, PC, or Mac for Hi-Res music streaming with superior quality. Its upgraded ESS DAC supports DSD for diverse Hi-Res music formats. Additionally, the A25 includes Bluetooth with Qualcomm AptX Adaptive technology, enabling up to 24-bit Hi-Res wireless music streaming from compatible devices for better-than-CD quality.

Versatile Connectivity with the A25 Amplifier

The A25 amplifier supports both Bluetooth and wired headphones, offering flexible connectivity options. Its two-way Bluetooth connectivity allows pairing with Bluetooth headphones for wireless freedom, while a front-mounted headphone socket accommodates any wired headphones.

Additionally, it supports analog sources with three RCA phono inputs, ensuring compatibility with devices like FM tuners.

A Concert in Speaker Form

The KEF Q Concerto META honours the classic Concerto, originally launched in 1969, by making high-fidelity audio more accessible for home use. As the first 3-way bookshelf speaker in the Q Series, it integrates advanced technology from KEF’s higher-end ranges, including The Reference and R Series. The Concerto META features the latest Uni-Q driver array, enhanced bass, and a sleek cabinet design, delivering superior performance and modern aesthetics.

The Q Concerto META benefits from a larger cabinet and an additional LF driver, resulting in improved frequency separation, more pronounced bass, and clearer stereo imaging. This combination of features ensures a richer, more detailed sound experience, making it an excellent choice for stereo setups and home theatre systems in medium to smaller rooms.

Building on KEF’s award-winning heritage, the Q Series now includes the latest 12th generation Uni-Q driver array and Metamaterial Absorption Technology (MAT™).

This iteration offers enhanced sound clarity and reduced distortion through a refined 3-way design and revolutionary sound absorption. The Q Series also incorporates Shadow Flare technology to minimise cabinet diffraction, ensuring precise and immersive audio for both music and cinematic experiences.
