Cambridge Audio Evo 300 – when one box may finally be enough

Cambridge Audio has introduced the Evo 300, the brand's most powerful Evo streaming amplifier to date. With 300 watts per channel, Hypex NCOREx amplification, an ESS Sabre DAC, HDMI eARC, MM phono input and the StreamMagic platform, it is not merely a convenience product on paper. It is a serious statement about the future of modern hi-fi.

Fewer boxes, higher expectations

In the past, a proper hi-fi system was often built from several separate worlds. You had an amplifier, a CD player, a DAC, a tuner, later a streamer, a separate phono stage, cables, racks, stands, and of course the eternal question: what sounds best with what?

Today, however, more and more manufacturers are trying to compress all of this into a single device. Not only because it looks cleaner in the living room, but also because listening habits have changed completely. Streaming, TV sound, vinyl, computer audio, NAS, smartphone playback – everything is expected to fit into one system.

The Cambridge Audio Evo 300 is a direct answer to this shift. It is not the first product of its kind on the market, but based on its specifications, it takes the idea of "one box, but not as a compromise" very seriously.

What does the Evo 300 offer?

The Evo 300 is Cambridge Audio's new premium streaming amplifier, offering 300 watts per channel with Hypex NCOREx amplifier modules. According to the manufacturer, the aim is to deliver greater dynamics, tighter bass and more stable speaker control, even with more demanding loudspeakers. Its internal design uses a dual-mono architecture, a balanced preamplifier stage and separate analogue volume control for each channel.

The digital section is built around an ESS Sabre ES9038Q2M DAC. According to early reports, the Evo 300 can handle up to 32-bit / 768 kHz PCM and DSD512, which on paper reaches well beyond most modern high-resolution listening needs.

The source side is also strong: StreamMagic Gen 4 platform, Spotify, TIDAL, Qobuz, AirPlay 2, Cast, Roon, UPnP and internet radio support. In addition, the unit includes HDMI eARC for TV use, USB for computer connection, RCA and XLR inputs, Bluetooth 5.4 with aptX HD, and a built-in MM phono stage for turntables.

Are TV and hi-fi finally no longer enemies?

One of the most interesting details is HDMI eARC. At first glance, this might seem like a small feature, but I think it clearly shows where modern hi-fi is heading. In today's living rooms, the TV is often in the same space where we listen to music. Traditional hi-fi thinking treated these as separate worlds for a long time: hi-fi was hi-fi, home cinema was home cinema.

The Evo 300 takes a different view: why should a good stereo system not also be the centre of TV sound?

This is not necessarily a home cinema approach. It is more like quality living-room audio. Two good loudspeakers, one powerful central unit, proper streaming, TV sound, vinyl, phone and computer connection – without needing six separate components.

Vinyl inside a modern digital hub

I especially like that Cambridge Audio has not left out the MM phono input. That says a lot about where vinyl stands today. It is no longer just a retro side story, but a natural part of many modern systems.

Of course, a built-in phono stage will not always replace a serious separate phono preamp, but for most users it is a huge advantage not to need another box straight away. With a decent MM cartridge turntable, you can get started immediately. The Evo 300 also includes a grounding point for turntable use.

The big question: real hi-fi or comfortable luxury?

This is where things get interesting. With products like this, the same question always comes up: is this truly hi-fi, or just an elegant, expensive, multi-function box?

In the case of the Evo 300, the answer is probably not black and white. The 300-watt Hypex NCOREx amplification, dual-mono layout, balanced preamp section and ESS Sabre DAC suggest that this is not merely a design object. At the same time, an all-in-one system always follows a different philosophy from a traditional component-based hi-fi setup.

The advantage of a separate system is that every element can be changed, upgraded and fine-tuned individually. The advantage of the Evo 300 is that it thinks as a complete system: shorter signal paths, fewer cables, fewer matching problems, easier operation and a smaller footprint.

For many listeners today, that matters more than having five separate boxes on the rack.

From a service technician's point of view

One of the fascinating, but slightly sensitive, points of modern all-in-one hi-fi is long-term sustainability. With a classic vintage amplifier, we often know exactly what can be repaired, what can be replaced and how the unit can be kept alive for decades.

A modern streaming amplifier is a different world. It contains a digital platform, network section, software, DAC, HDMI, Bluetooth, control system, display and amplifier modules. This is convenient and modern, but in the long run, software support, parts availability and modular repairability will also become important questions.

That is why, with a device like this, it is not enough to look only at what it can do when new. It is also worth looking at how stable the manufacturer's ecosystem is behind it. Cambridge Audio's StreamMagic platform is a positive sign in this respect, because it is not a quickly assembled anonymous streaming solution, but a system the company has been developing for a long time.

Who is it for?

The Evo 300 is not for someone trying to build a hi-fi system on a shoestring budget. Its announced European price is around €3,999, with UK and US pricing at roughly £3,499 and $3,999.

That is a serious amount of money. However, considering that a single device includes an amplifier, streamer, DAC, phono stage, HDMI eARC input for TV use and advanced control, the positioning is not completely unrealistic.

It will be most interesting for those who want a serious but clean system. People who do not want a separate DAC, separate streamer, separate phono stage and separate pre/power amplifier combination, but still do not want to give up quality music listening.

Octonano opinion

In my view, the Evo 300 is not simply a new Cambridge Audio model. It is a good signpost for the current direction of hi-fi.

Classic hi-fi is not disappearing. Vintage amplifiers, CD players and turntables still have their own strong world. But alongside them, there is growing demand for systems that do not require a separate room, a dedicated equipment rack and a university degree just to operate.

The Evo 300 tries to capture exactly this balance: to be powerful enough, smart enough, beautiful enough and simple enough for music listening to be about the music again, not about the cabling.

The big question, of course, will be how it sounds in real life. Because at the end of the day, hi-fi is still not decided by the specification sheet, but by whether we sit down in front of it for one more album in the evening.
