Cambridge Audio EVO 300 – A 1,100 Watt Streaming Amplifier for the HIGH END Vienna 2026

Cambridge Audio has long understood that the modern HiFi system no longer needs to be an altar of separate boxes, provided the engineering behind the single box is taken seriously. The Cambridge Audio EVO 75 and Cambridge Audio EVO 150 established that point neatly: elegant All-in-One systems, built around Cambridge Audio StreamMagic, requiring little more than a suitable pair of loudspeakers to become a complete, genuinely capable music system. The Cambridge Audio EVO 150 SE Streaming Amplifier then sharpened the idea further, with Cambridge Audio placing particular emphasis on sonic refinement within the amplifier section. Now comes the Cambridge Audio EVO 300, and this is a rather different proposition. Unveiled at HIGH END Vienna 2026, it brings the Cambridge Audio EVO Series into a more muscular class, retaining the visual discipline and user convenience of the line while adding power reserves rarely seen in this category.

The Cambridge Audio EVO 300 is immediately recognisable as part of the Cambridge Audio EVO Series. Its low aluminium chassis, large colour display, magnetically attached side panels and carefully domestic proportions all follow the language already established by the Cambridge Audio EVO 75 and Cambridge Audio EVO 150. This is not a visually aggressive amplifier, nor does it try to mimic the imposing presence of traditional high-power separates.

The shift is internal, and it is substantial. Where the earlier EVO models made their case through elegance, compact integration and flexibility, the Cambridge Audio EVO 300 puts amplifier authority at the centre of the discussion. Cambridge Audio specifies a total output of 1,100 Watts RMS, with 2 x 300 Watts available into 8 Ohms and 2 x 550 Watts into 4 Ohms.

Those are not casual numbers in the world of compact Streaming Amplifiers. They suggest a product aimed at listeners who want the simplicity of an All-in-One system but still intend to drive demanding loudspeakers with proper control. In other words, the Cambridge Audio EVO 300 is not merely an EVO with more volume on tap. It is Cambridge Audio’s attempt to move the entire EVO idea closer to the territory usually occupied by a capable preamplifier and power amplifier combination.

Hypex NCOREx as the amplifier foundation

At the heart of the amplifier section is a Class D output stage based on Hypex NCOREx modules, tuned by Cambridge Audio to meet the company’s own sonic requirements. This is a very contemporary choice, and a sensible one. Hypex NCOREx gives Cambridge Audio the basis for high efficiency, considerable power and compact dimensions, while still allowing the amplifier to be voiced and implemented with attention to timing, control and low-level resolution.

Cambridge Audio has arranged the design as a dual-mono concept with separate power supply paths for the two channels. The individual sections responsible for digital-to-analogue conversion, preamplification and volume control are also said to be carefully separated. Particular attention is given to the analogue volume control, which uses channel-separated signal paths to help preserve stereo focus, dynamic range and detail retrieval.

The power supply is an important part of the story. Cambridge Audio uses a purpose-matched switch-mode power supply intended to keep the amplifier stable under sustained load rather than simply producing impressive figures for the specification sheet. That distinction matters. The appeal of the Cambridge Audio EVO 300 lies not only in its rated output, but in the promise that this output can be used meaningfully with loudspeakers that require grip, current and composure.

Cambridge Audio StreamMagic as the digital command centre

As with the previous EVO models, Cambridge Audio StreamMagic forms the digital core of the Cambridge Audio EVO 300. For Cambridge Audio, StreamMagic is no longer a mere streaming module. It has become the company’s control architecture for networked music systems, bringing services, protocols, app control and multiroom functions together in a mature platform.

The Cambridge Audio EVO 300 supports Spotify Lossless Connect, TIDAL Connect, Amazon Music, Deezer, Qobuz Connect, Roon Ready and UPnP. It also includes Google Cast, Apple AirPlay 2 and Bluetooth 5.4 with aptX HD and AAC. That gives the amplifier a broad set of options, whether it is used as the main system in a traditional HiFi room, integrated into a wider multiroom environment, or simply fed from a smartphone or tablet when convenience matters.

Integration with Google Home, Apple AirPlay and Roon Multiroom is also provided. This makes the Cambridge Audio EVO 300 more than a self-contained amplifier with streaming added. It is designed to sit comfortably in current networked audio environments without forcing the user into a single ecosystem.

Digital conversion is handled by an ESS Sabre ES9038Q2M DAC. It supports Linear PCM up to 32 Bit and 768 kHz as well as DSD512, giving the amplifier considerable headroom for high-resolution streaming, local playback and computer-based audio. In practical terms, it means the EVO 300 is unlikely to be caught short by today’s common Hi-res formats or by rather more demanding library-based playback.

HDMI eARC, phono and classic HiFi connectivity

The Cambridge Audio EVO 300 is not solely a streamer with loudspeaker terminals. Its physical connectivity is unusually comprehensive for such a compact amplifier. HDMI eARC allows it to be connected neatly to a television, making the system suitable for modern living-room use without reducing it to soundbar territory. Digital sources can be connected via USB-B, optical S/PDIF and coaxial S/PDIF.

The analogue side is equally important. The Cambridge Audio EVO 300 offers a balanced XLR input, two pairs of Cinch inputs and an integrated MM phono stage. That last detail is worth noting, because it keeps the turntable within the same elegant system logic as streaming, television sound and digital sources. No external phono stage is required for a moving-magnet cartridge.

A 6.3 mm headphone output is located on the front panel. The amplifier also provides preamplifier outputs, allowing it to feed an external power amplifier or active loudspeakers, and there is a variable subwoofer output with independent level and crossover adjustment. Cambridge Audio also provides optional high-pass filtering to relieve the main loudspeakers when a subwoofer is in use. That is the sort of feature that can make a real difference in practice, particularly in rooms where controlled bass integration is more important than merely adding more low frequency output.

EVO design, scaled for the living room

Visually, the Cambridge Audio EVO 300 remains true to the established EVO identity. The chassis is 39 cm wide and only 9 cm high, so despite the considerable power on offer, it remains compact enough for a normal living space. The aluminium casework gives it the cool restraint expected from the series, while the interchangeable magnetic side panels allow a choice between real wood veneer and matt black.

The 7.8 inch colour display dominates the front panel. It can show album artwork, classic VU meters or level meters, turning the EVO 300 into a product that is not merely operated but also looked at. That matters in this category. A modern All-in-One Streaming Amplifier is usually placed where people live, not hidden away in a rack in another room. The Cambridge Audio EVO 300 accepts that reality and treats the interface as part of the product’s character.

Conclusion

With the Cambridge Audio EVO 300, Cambridge Audio strengthens the Cambridge Audio EVO Series precisely where compact All-in-One systems can sometimes feel limited: real amplifier headroom. A rated 2 x 550 Watts RMS into 4 Ohms is a clear statement in this class, particularly as Cambridge Audio is not positioning the amplifier as a stripped-back powerhouse but as a fully equipped Streaming Amplifier with HDMI eARC, phono, XLR, Roon Ready, Qobuz Connect and StreamMagic. For listeners who want an elegant, compact system but do not wish to step down in loudspeaker control, dynamic authority or connectivity, the Cambridge Audio EVO 300 could become one of the more interesting integrated systems of the year.
