Arcam A5+ Integrated Amplifier – Bluetooth 5.4, Auracast

Meet the Arcam A5+ - a modern, musical 50W/ch Class AB integrated amplifier that makes hi-fi effortless, whether you spin vinyl, stream digitally, or share wirelessly. Inside is an ESS ES9018 DAC for clean, detailed conversion, hi-res optical/coaxial inputs, and a meticulously tuned MM phono stage that treats records with the care they deserve. The latest Bluetooth 5.4 with Snapdragon Sound brings aptX Lossless and Auracast broadcast, so you can listen in true CD-quality over wireless and share to multiple compatible headphones or speakers without pairing. Finished with solid aluminum panels and quality dials—and practical touches like pre-outs and a dedicated headphone output—A5+ is the compact centerpiece for a serious two-channel system.
