Cambridge Audio Evo 300 Premium Streaming Amplifier

A 300 Wpc premium streaming amplifier with Hypex NCOREx amplification, dual-mono architecture, balanced preamp circuitry, HDMI eARC, MM phonostage, and StreamMagic Gen 4

The Cambridge Audio Evo 300 is a flagship all-in-one streaming amplifier designed to simplify a serious two-channel system without giving up power, source flexibility, or control. Its Hypex NCOREx class-D amplification delivers 300 Wpc into 8 ohms, with dual-mono architecture, a balanced preamp stage, and dedicated analog volume controls helping preserve stereo separation and low-level detail.

Built around Cambridge Audio’s StreamMagic Gen 4 platform, the Evo 300 brings streaming services, Internet Radio, UPnP libraries, local USB media, AirPlay 2, Chromecast built-in, and Roon Ready support into one elegant component. The ESS Sabre ES9038Q2M DAC supports high-resolution playback up to 32-bit/768 kHz PCM and DSD512 through USB Class 2.

The Evo 300 is also designed to handle a full range of physical sources. HDMI eARC connects a TV, while optical, coaxial, USB audio, analog RCA, balanced XLR, Bluetooth, and a moving-magnet phonostage let the Evo 300 serve as the hub of a complete music and entertainment system.

App-controlled bass management allows crossover, level, and phase adjustment for subwoofer integration, while Speakers A + B outputs provide flexibility for two speaker zones. A 7.8" display shows album art, meters, and playback information, and interchangeable side panels allow the Evo 300 to suit different rooms and systems.
