"The A5+ is a wonderful addition to Arcam’s family of amplifiers, offering a sound that blends class-leading insight with a tangible sense of musicality."
The Arcam A5+ is perfect for music lovers who want to enjoy high-quality listening with family and friends, whether through loudspeakers or headphones. Building on the award-winning Arcam Radia A5, the A5+ takes things further with an enhanced power supply and even more versatile connectivity. The result is a cleaner, more dynamic sound with extra headroom that makes a real difference when driving a pair of quality speakers.
New wireless features also set it apart from the original A5. With Snapdragon Sound, you get uncompressed audio over Bluetooth, while Auracast lets you share the same track wirelessly across multiple compatible headphones or speakers without pairing. Alongside digital and analogue inputs, the finely tuned phono stage ensures your vinyl playback is as detailed and engaging as your streaming sources. With these thoughtful upgrades, the A5+ combines the musicality of the A5 with added power and convenience for today's listening habits.
The KEF Q Concerto Meta pays homage to KEF's classic 1969 model, created for modern audiophiles and home cinema enthusiasts while celebrating a golden age of music. It incorporates engineering advancements like KEF's proprietary Metamaterial Absorption Technology (MAT), which also features in the award-winning KEF R3 Meta and absorbs 99 per cent of unwanted noise from the rear of the tweeter. Their signature Uni-Q driver array, now in its 12th generation, also ensures sound quality that's free from distortion and dispersed evenly throughout the room.
To achieve clarity and depth, this speaker features a three-way layout that separates high, mid, and low frequencies, with a crossover that was refined over 1,000 measurements in an anechoic chamber to attain the optimal signal path. The 6.5-inch hybrid aluminium bass driver ensures tight, deep bass, while the magnetic grilles maintain a sleek appearance, protecting the drivers from damage and debris when attached. Available in black, white, and walnut, the KEF Q Concerto Meta is a stylish bookshelf speaker set to complement high-performance audio setups.
