The Cambridge Audio Evo 300 is an all-in-one streaming amplifier that puts 300 watts per channel, a network streamer, a high-resolution DAC and a moving magnet phono stage into a single chassis. It is the most powerful Evo to date, driven by dual-mono Hypex NCOREx amplification and fronted by a 7.8-inch color display, built to run a genuinely demanding pair of speakers straight out of the box.
Cambridge Audio has engineered audio in London since 1968, with a house philosophy it calls Great British Sound: accurate and musical, without artificial coloration. The Evo line distills that thinking into a one-box system, and the Evo 300 sits at the top of that range as its most capable model.
At the heart of the Evo 300 is Hypex NCOREx Class D amplification arranged in a dual-mono layout, with a separate amplifier for each channel. It produces 300 watts per channel into 8 ohms and 550 watts per channel into 4 ohms with both channels driven, enough headroom to control power-hungry floorstanders and larger rooms that the smaller Evo models leave on the table. The dual-mono design keeps the left and right signal paths independent for cleaner separation and a wider, more stable soundstage.
Digital conversion runs through an ESS Sabre ES9038Q2M DAC supporting up to 32-bit/768kHz PCM and DSD512. The Evo 300 preserves the resolution of your files and streams without unnecessary resampling. It plays the full range of formats, from compressed MP3 and AAC up to high-resolution FLAC, WAV, ALAC, AIFF and native DSD.
The Evo 300 is built on the fourth generation of Cambridge Audio's StreamMagic platform. It supports Spotify Connect, TIDAL Connect and Qobuz Connect natively, with Deezer and Amazon Music alongside internet radio and UPnP playback from a home network. It is Roon Ready, works with AirPlay 2 and Chromecast built-in, and adds Bluetooth 5.4 for quick connections from a phone or laptop. Everything is managed through the StreamMagic app or directly from the front panel.
The rear panel is built to be the hub of a full system. HDMI eARC brings your television in with single-remote volume control, and the moving magnet phono input takes a turntable directly. Balanced XLR sits alongside two RCA line inputs for analogue sources, while optical, coaxial and USB audio handle digital. Outputs include speaker terminals for two pairs (A and B), a subwoofer output, a preamp output, and a 6.35mm headphone jack on the front.
The Evo 300 carries the largest screen Cambridge Audio has ever put on a hi-fi component. The 7.8-inch color display shows album artwork, track and artist information, source and sample rate clearly from across the room, turning the amplifier into the visual centerpiece of the system rather than a black box on the rack.
A dedicated moving magnet phono stage is built in, so a turntable connects straight to the Evo 300 with no outboard preamp. It preserves the character and detail of vinyl while keeping the system to a single box.
The magnetic side panels lift off and swap by hand. The Evo 300 ships with two full sets, a real wood veneer for a warmer, traditional look and a tech-style black for a more modern one, so the same amplifier can dress up or down to match your space.
The Evo 300 is the flagship of Cambridge Audio's all-in-one Evo lineup.

The new Evo 300 takes that concept much further, adding serious power, dual mono architecture, the new Hypex Ncore X amplification, and the kind of connectivity that could make it the centerpiece of a very high-end two-channel audio system.
