The Arcam Radia A5 Integrated Amplifier represents 45 years of accessible high-fidelity sound, being developed by the world-class British home audio manufacturer. This is the first of three amps in the Radia series; a series dedicated to musical clarity and transparency. As such, particular care has been given to choosing and testing the materials and components used in the A5. Unleash the potential of your speakers with 50W per channel (into eight-ohms). The Class AB amplification ensures enhanced performance and exceptional clarity.
A blend of quality and connectivity, this amplifier features hi-res digital optical and coaxial inputs and up to three analogue RCA. It also hosts a dedicated Phono MM input, giving vinyl enthusiasts a direct link for their turntable and record collection. The built-in ESS ES9018 DAC ensures impeccable signal conversion, resulting in a pristine and faithful reproduction of digital sources.
The Arcam A5 is also equipped with Bluetooth 5.2, featuring aptX Adaptive technology. This guarantees reliable wireless connectivity, letting you stream music from any compatible Bluetooth-enabled device in up to 24-bit HD audio. Furthermore, the A5 also supports Bluetooth headphones as well as traditional wired, meaning you choose how you enjoy your private listening sessions. This amp boasts solid aluminium dials, as well as front, top, sides, and rear panels. Not only does this enhance its durability, but it also adds a touch of elegance to your audio setup.
The KEF Q350 speakers are equipped with a 165mm Uni-Q driver and 25mm vented aluminium tweeter. The combination of these in one central driver unit forms the signative Uni-Q Driver Array, featured throughout the Q Series. This driver array will deliver your high and mid-range frequencies in a seamless blend that elevates your entertainment experiences. The aluminium tweeter cone is home to Z-Flex technology, contributing to reduced distortion. With the addition of a waveguide, the KEF Q350 speaker creates a wide-reaching sound that you'll love listening to.
The KEF Q350 bookshelf speakers offer great sounds that are matched by their good looks. Grilles are sold separately, but, honestly, these speakers look so sleek and simplistic without them!
