Product Information
The flagship Arcam A25 delivers truly powerful sound, the widest range of connectivity and luxury styling to create an amplifier that’s packed full of talent.
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.
Power and control from the Class-G amp
Drawing on over 45 years’ experience in amps, Arcam have set a new class standard for sound quality. Using a unique Class-G amplifier gives the A25 generous power and incredibly low distortion. With 100 watts per channel, this is Arcam’s most powerful Radia amplifier. This means deep, powerful bass and punchy sound, even in larger rooms and with low efficiency speakers.
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.
Hi-Res sound via USB-C input
Unique to the A25 model, this Arcam amplifier features a USB-C input. Connect laptop, PC or Mac and enjoy Hi-Res music streaming to the highest quality standards. Using an upgraded ESS DAC (Digital to Analogue Convertor), the A25 supports DSD (Direct Stream Digital) for the widest choice of Hi-Res music format support.
Stream from your smartphone in Hi-Res audio
For simple yet high quality music streaming, the A15 features Bluetooth with Qualcomm AptX Adaptive technology. When used with a compatible source device, this delivers up to 24-bit Hi-Res music streaming, giving you better than CD-quality, from a wireless connection.
Connect your headphones – Bluetooth or wired
The A25 welcomes all types of headphones, however they connect. Two-way Bluetooth connectivity lets you pair the amp with your Bluetooth headphones, giving you the freedom of movement that only wireless connectivity brings. Alternatively, the A25 also has a facia-mounted headphone socket for any type of wired headphones.
Connect all your digital and analogue sources
Featuring a premium quality, built-in DAC (Digital to Analogue Convertor), the A25 optimises the sound from your digital audio sources. USB-C, two coaxial and one optical input let you connect your computer, TV, games console and digital music source. For analogue sources, such as an FM tuner, there are also three RCA phono inputs.
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.
Enjoy Arcam’s ultimate sound quality, with the A25.
”For yet another year the KEF LS50 Meta speakers remain the class leader at this level.” ’What Hi-Fi?’ 2023 award-winner.
Improving an icon
Launched in 2011, the original KEF LS50 was a smash-hit from day one. The new KEF LS50 Meta takes all the award-winning ingredients of the original and introduces new technology for sensational sound quality.
Hear the sound, just as it should be, with MAT
Developed in conjunction with Acoustic Metamaterials Group, the LS50 Meta makes use of an exciting new technology called MAT (Metamaterial Absorption Technology). The revolutionary material absorbs 99% of unwanted sound from the rear of the tweeter, for lower distortion and a much purer, more natural sound.
Legendary Uni-Q drive units deliver studio quality sound
KEF’s history includes making some of the most precise-sounding monitor speakers. Used in recording studios around the world, KEF-branded speakers and other brands using KEF drive units are behind so many classic mixes. Now in its 12th generation, the Uni-Q driver array places the revised tweeter within the middle of the woofer, creating a more cohesive sound. The magnesium/ aluminium woofer is light and rigid – making it fast to respond and entirely faithful to the music playing.
Foot-tappingly musical
Although some monitor speakers can sound clinical to listen to, this is not the case with the KEF LS50 Meta. The super-rigid cabinet features a curved compound front baffle. Combined with the tweeter’s ‘tangerine’ wave-guide, this helps spread the sound far out into your room – making listening to these speakers an enveloping experience, wherever you’re sitting in the room.
Punchy, lifelike bass
For such small speakers, the LS50 Metas hit hard. Thanks to Z-Flex surrounds, the woofers move across an extended range, giving deep, powerful bass. More important than just being ‘deep’, the bass is extremely well controlled and lifelike. The computer-aided design of the rear port promotes flow and reduces turbulence – meaning the bass sounds fast and accurate.
A design classic
Just as enduring as the sound, the LS50 Meta’s design has similar long-lasting appeal. The smooth, clean design is striking yet still easy on the eye. Choose between Carbon Black, Mineral White, Titanium Grey or Royal Blue, for the style that best suits you.
