The award-winning Cambridge Audio EVO 150 has quickly become one of the most talked-about all-in-one amplifiers in the hi-fi world. Combining modern design, powerful amplification, and streaming capabilities into a single, sleek package, it aims to simplify high-quality audio for both seasoned audiophiles and those upgrading from basic setups. But does it live up to the hype? After extensive testing, we think it does.

A Design That Blends Modern and Classic

First impressions matter, and the EVO 150 makes a strong one. It’s compact, elegant, and feels like it belongs in a high-end living space. The front is dominated by a bright color display that shows album art and system settings, while a smooth metal volume knob adds a satisfying tactile element. One thoughtful touch is the inclusion of magnetically swappable side panels, letting you choose between a warm wood finish or a more contemporary black Richlite panel.

All the Features You Actually Need

A big part of the EVO 150’s appeal is that it consolidates multiple components into one box. No need for a separate DAC, streamer, or phono stage. It’s all here.

It supports a wide range of inputs, including USB, coaxial, optical, balanced XLR, and unbalanced RCA. Vinyl fans will appreciate the built-in moving magnet phono stage, which is clean and quiet enough to do justice to high-end cartridges. For TV integration, the HDMI ARC input makes it easy to route audio through your main speakers without complicated setups.

On the streaming side, Cambridge’s StreamMagic app supports all of the most popular streaming platforms like Tidal, Qobuz, Spotify Connect, and internet radio, with full high-resolution playback. At the core of it all is a high-performance ESS Sabre DAC, which helps deliver exceptional detail and clarity across digital sources.

The StreamMagic app is straightforward and reliable, even if it doesn’t offer extensive tone-shaping controls or room correction. That simplicity works in its favor for a majority of customers — less time tweaking settings, more time enjoying music.

Power Under the Hood

The EVO 150 uses a Hypex Ncore Class D amplifier module, a design known for its high efficiency and low distortion. It delivers 150 watts per channel into 8 ohms and roughly 250 watts into 4 ohms, giving it enough muscle to drive even more demanding speaker setups with ease. Whether you're listening at low volumes or really pushing the system, the EVO 150 maintains composure and authority.

In real-world use, the amp handles dynamic shifts effortlessly. Bass notes are tight and articulate, mids remain open and expressive, and the treble has just the right amount of sparkle without ever becoming harsh. There's a sense of ease and headroom that makes longer listening sessions fatigue-free, even with complex or high-energy music.

One feature that adds to its versatility is the A/B speaker switching, which gives the EVO 150 the option to add speakers if the user finds themselves in need of a second set. This is perfect if you want to run a second set in another room or switch between two different speaker types depending on your mood. You can toggle between Speaker A, Speaker B, or run both simultaneously from the front panel or the remote.

That said, it’s important to be mindful of speaker impedance when running both pairs at once. Cambridge suggests using 8-ohm speakers if you are using both A and B outputs together. Using two 4-ohm pairs at the same time may lower the load too much for the amp to handle safely.

With this level of flexibility, the EVO 150 is more than capable of being the hub of a multi-room or multi-speaker setup.

How Does It Sound?

The most important question is how it performs sonically, and the EVO 150 doesn’t disappoint. Its character is best described as neutral with a touch of punch. It doesn’t color the sound heavily, which is exactly what you want from an amplifier at this level. Instead, it brings out the natural qualities of your speakers and the recording itself.

Listening to acoustic tracks, the amp renders vocals with lifelike texture and presence. With more aggressive rock or electronic music, the low-end punch adds energy without becoming overwhelming. The soundstage is wide and layered, giving instruments room to breathe.

What stands out is how easy it is to just listen. The EVO 150 doesn’t demand your attention with gimmicky sound tricks; it simply presents the music as it should be.

Testing With Different Speakers

To really get a sense of how this amplifier interacts with different pairs of speakers, we tested it with Klipsch Heresy IV and Sonus Faber Sonetto V speakers.

Klipsch Heresy IV

Sonus Faber Sonetto V

The Klipsch Heresy IV is known for its lively, dynamic presentation. Paired with the EVO 150, the Heresy IV kept its trademark energy, with the amplifier adding just enough weight to the low end to make the sound fuller. The horns stayed crisp without becoming harsh, showing how well the EVO 150 keeps everything balanced.

That said, if you’re willing to sacrifice some modern convenience in exchange for a warmer, more natural sound, we recommend pairing the Heresy IV with a tube amplifier like the Rogue Audio Cronus Magnum III. The tube-driven design helps tame the natural sharpness of the Klipsch horns while preserving their dynamic energy.

With the Sonus Faber Sonetto V, a more refined and slightly warm speaker, the EVO 150’s subtle low-frequency boost complemented the sound beautifully. The Sonetto V doesn’t have the same bass authority as its larger sibling, the Sonetto VIII, so the EVO 150’s punch gave it extra body while still letting its smooth midrange and airy highs shine through.

Our experience in these tests showed that the amplifier has a way of enhancing without overpowering, letting the natural voice of the speakers and the characteristics of the musical recording come through.

Everyday Use and User Experience

Using the EVO 150 day to day is a pleasure. The large display makes it easy to see what’s playing, the volume control is responsive, and switching inputs is quick. The included remote is solid, although its minimalist design may take a little getting used to.

Streaming through the StreamMagic app is simple and reliable. While some users might wish for more advanced EQ options, we found the straightforward interface refreshing. Most people will never feel the need to adjust beyond the basics.

Strengths and Limitations

No product is perfect, and while the EVO 150 comes close, there are a few things to note.

On the positive side, it delivers an impressive combination of power, clarity, and convenience. Its build quality is excellent, and it’s versatile enough to handle almost any source you throw at it. The subtle punch in its sound signature adds life without distortion.

On the downside, there’s no bass management or room correction, which some competitors offer. The app, while functional, lacks deeper customization options. These are minor points considering how well the amplifier performs overall.
