ARCAM A25

Sleek new look with powerful sound

Arcam components are known for their clear, spacious sound, so we're excited to try out the A25 integrated amplifier. It's the most feature-rich of the company's new line of Radia integrated amps, which sport a luxurious new visual style. It's got a solid build, too, with an aluminum chassis and chunky aluminum dials backlit in eye-catching yellow. But the real story is the hi-fi goodness that lies within.

Class G amplification and a superior DAC

Class G amplification provides super-clean Class A performance at low levels, and it uses efficient "rail-switching" technology to bring in a higher power supply with low distortion when necessary for more demanding dynamic peaks. It's a technology that gets high marks from our customers for its clean musicality. Your digital sources get audiophile-level treatment from the built-in high-performance ESS PRO DAC.

Convenient connections

The A25 gives you plenty of options for connecting music sources. There are multiple digital inputs, including Toslink optical, coaxial, and even a USB-C connection for playing high-res files from your computer. Three line-level stereo RCA inputs are available for your analog audio components or a separate DAC. For vinyl enthusiasts, there's a moving magnet phono input.

The A25 has built-in Bluetooth with high-res aptX™ Adaptive technology for streaming music via online services from compatible devices. Two-way directionality allows you to stream from the amp to compatible headphones or powered speakers.

For robust Wi-Fi streaming, you can add Arcam's matching ST5 network music player. Or use one of the digital connections to connect Arcam's matching CD player or your TV.

A stereo line-level preamp output lets you add a powered subwoofer or connect a separate amplifier.
