SX50 are a pair of compact hi-fi speakers designed to sit in confined spaces like bookshelves – hence the name. Despite their modest size, they output a confident, detailed, and rich stereo sound to fill smaller rooms with music as it was meant to be heard. It's the combination of engineering quality and value, that make SX50 so hard to beat.
Sound Reproduction
SX50 speakers have a 135mm (5.25") woofer made from treated paper. Hi-fi manufacturers have used it for years, as paper's impressive strength-to-weight ratio is matched by excellent tonality – so music sounds rich, well defined, and real. 25mm (1") soft dome tweeters, made from treated silk, take care of the higher frequencies – with the same balance of realism and refinement.
Two Drivers, One Voice
Our team in London took great care and attention when designing the crossovers in SX50 – as they're responsible for ensuring that each driver receives the correct frequency. Accuracy of timing and stereo imaging depend on phase remaining completely linear, from top to bottom. The result? Your music sounds engaging, energetic and real.
Engineered, Front to Back
Spin SX50 around to see that our attention-to-detail runs from front to back. There's a neat bass reflex port that lets you fine-tune lower frequencies, by adjusting the position of the speaker with the wall. Immediately below are a pair o...
Brand highlights
Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:
- Cambridge Audio incorporates high-quality components, such as toroidal transformers and ESS Sabre DAC chips, but they make sure that the components are chosen for their sonic character, rather than measured performance.
- With some lines receiving 5-year warranties with product registration, they convey a commitment to product durability, even when their products are sold through hifi stores, which are not generally known for high-end clientele.

- Positioning: The high-end integrated amplifier in the EX series, offering advanced features and performance.
- Description: Delivers 100 watts per channel with Class AB amplification, providing a wide and detailed soundstage. It includes digital inputs like HDMI eARC and Bluetooth aptX HD, unlike the AXA25, which focuses on analog connections.

Every critical component of Evo S has been chosen with one aim in mind: to deliver class-leading audio performance.

Video review
Our take on the brand
Wharfedale’s new EVO4 has grown out of the extensive research and development that produced the ELYSIAN flagship loudspeakers and borrows much of the technology involved in ELYSIAN.
Our summary
Product Strengths
- Excellent focus and separation, with the speakers 'disappearing' to create a natural soundstage
- Impressive low-end performance, adding authority to the music
- Cohesive driver integration, with no perceivable handover between the AMT tweeter, midrange dome, and woofer
- Remarkable neutrality in the midrange, with a detailed yet smooth treble—avoiding harshness even at higher volumes
- Clear and detailed sound reproduction, extracting nuances and levels of information outstanding for its price
Product Considerations
- Vertical off-axis performance of the AMT tweeter is not good, so correct speaker height and toe-in are important
- Soundstage is not super wide, with the presentation mostly between the speakers
- Some reviewers found the aesthetics or proportions to be awkward or not to suit all tastes
- Bass may be a bit polite for some listeners wanting subwoofer-type rumble
- The midrange can be fatiguing if the listener's ear is at the midrange driver level
Takeaway: The Evo4.2 is a well-rounded speaker that delivers excellent sound quality with impressive imaging, detail, and tonal balance. It is capable of providing an audiophile experience at an affordable price.

Our take on the brand
Our summary
Product Strengths
- Attractive design with rounded cabinet edges and multiple finish options (Satin Black, Satin White, Santos Rosewood, Holme Oak)
- Good midrange reproduction—clean and uncolored—especially for the price
- Clear and detailed sound with good separation of instruments
- Taut and agile bass performance
- Internal bracing (P2P) stiffens the cabinet, reducing vibrations and improving stereo image
- Connectivity options such as binding posts
Product Considerations
- Can tend towards brightness, potentially causing fatigue during longer listening sessions—especially with the wrong equipment pairing
- Cabinet size is relatively large for a bookshelf speaker
- Bass response is somewhat subdued
- Some reviewers noted imaging issues, with vocals lacking a firm presence in the center
- Grilles muddle the sound
Takeaway: The Q Acoustics 5020 is a great-looking speaker that offers a rich and musical sound, making it a very entertaining listen for the price. With its ability to reveal details from recordings, it's a wise choice for those looking for a well-built and sonically pleasing speaker.

Our take on the brand
Product Strengths
- Larger horn tweeter and a new Cerametallic woofer, compared to its predecessor
- Upgraded binding posts and crossover plate elevate to Reference Premiere status
- Larger diameter voice coils and aluminum shorting rings on the woofers give the speaker better linearity throughout the bass, decrease distortion while upping power handling resulting in improved speed and accuracy
- Better detail retrieval, more articulate bass, and vastly improved soundstage width and imaging, compared to the RP-600M
- The binding posts are the same that are found on costlier Heritage speakers
Product Considerations
- Finish options did not receive an upgrade over the outgoing model, leaving customers with the same ebony or walnut wraps
- The tweeter may be too bright for some listeners who are sensitive to a more aggressive top end
- Rated sensitivity is 94.5dB, which is a decrease compared to the original's reported sensitivity of 96
- Needs a bit of space behind them and to the sides, or at least positioning on open shelves, if the powerful output from that port isn't to muddy the sound
Comparisons (according to reviewers)
- Compared to the older RP-600M, the new sounds far more linear
- The new is very easy to listen to for long periods of time, and while it still has a presence, a speed and transparency to the artist or instrument—at least with respect to the midrange—it is not as forward sounding as past designs
- The new proved to be surprisingly flat, but best of all, not the least bit fatiguing
- There was very little difference in tone with respect to the mids between the new and a costlier Revel bookshelf
- These two are actually pretty neck and neck
- As for the Wharfedale Evo 4.1, the Evo is better constructed, not to mention nicer looking
Takeaway: The RP-600M II is a refined speaker with better components, improved sound, and better bass response and imaging. It's a speaker that would be great for someone who likes to listen to a variety of music genres and wants a good-sounding speaker that can last a long time.

- Good at detail, intelligibility, clarity, and dynamics from about the midrange on up
Product Considerations
- Require a sub for full-range playback

- Vs Q Acoustics 3010i, the Cambridge is more captivating
- Vs Fluance XL8s, the Cambridge has a bit more detail and definition throughout the mid-range and treble
- Vs Wharfedale Diamond 121, the Wharfedales have a clearer sound, with greater dynamic reach
Takeaway: The SX60 speakers are pretty special, especially if detail, intelligibility, clarity, and dynamics from about the midrange on up are prioritized, and they do not command a premium price. These speakers are confident and full of energy, making them an engaging and fun listen.

Our Summary
Product Strengths
- Nice cabinets
- Fluid and captivating articulation in the mids, with warmth and clarity to voices
- The bass is good enough that one could conceivably get away without ever having a subwoofer
- Excellent clarity and tonal balance
- Able to use so much high-performance technology in products that cost so little
Product Considerations
- Has aluminum wiring
- Lacks a little bit of detail at the very top—kicks, punches, and gunshots do not quite have enough "snap" to them
- Rated at 8 ohms, but in reality, they are 4 ohm speakers
- Do not have magnetic grills, they have a pin-and-cup grill retention system
- Tendency to sound bright with modern pop and electronic music
Comparisons (according to reviewers)
- Compared to the SVS Prime Bookshelf Speaker, it is a noticeable step up in linearity
- The Ultra Towers' performance is beaten by perhaps only one or two other models in the same price range
- The SVS's more laid-back character and natural response remains composed compared to the JBLs, where the JBLs start to lose control and break up
Takeaway: The Ultra speakers are a good value because of their high-quality sound and build that offer performance often found in more expensive speakers. One can enjoy great sound without breaking the bank.
