Arcam Radia A25+ Integrated Amplifier
Full Details
Smooth, Clean, Dynamic, Spacious: 100Wpc Arcam Radia A25+ Integrated Amplifier Includes HDMI eARC, USB-C Input for DSD1024 and 32-Bit PCM, Wireless Bluetooth and Auracast Ability
More than four decades spent designing high-end amplifiers have culminated in the Arcam A25+ integrated amplifier, the flagship of the English company’s Radia Series and evidence why expertise, experience, and engineering matter when it comes to quality audio. Featuring fifth-generation Class G amplification, A25+ outputs a strapping 100Wpc and plays with the cleanliness, smoothness, dynamics, and spaciousness for which the approach is known.
Equipped with an ESS ES9018K2M DAC, enhanced power supply, three pairs of line-level inputs, an HDMI eARC input for your TV, and a stereo preamp output, A25+ handles traditional and wireless digital. A USB-C input stands at the ready for your laptop or tablet — and processes up to 32-bit/384kHz and DSD1024. A built-in MM phonostage awaits your turntable. The 19.9-pound A25+ also touts one optical and two coaxial outputs. Want to listen in private once the lights go down? Plug into the front-panel headphone output or connect wirelessly. Built-in Snapdragon Sound (via Bluetooth) and Auracast broaden the possibilities.
Surrounded by a vibration-resistant aluminum chassis, A25+ looks as clean as it sounds. Don’t miss the impressive rated specs — total harmonic distortion and signal-to-noise ratio, especially — for verification that what you’ll experience will come across with alluring purity, naturalism, detail, and definition. A five-year manufacturer warranty, remote control, and our Satisfaction Guarantee come standard.
