Our Review

Cambridge Audio Edge W Power Amplifier Review


Cambridge Audio has long established itself as a purveyor of high-fidelity audio equipment, marrying British engineering with a passion for authentic sound reproduction. The Edge W Power Amplifier is a testament to that heritage, promising a listening experience that is as close to the original recording as possible. With its sleek design and robust specifications, the Edge W makes a compelling case for audiophiles seeking a premium amplifier.

Design and Build Quality


At first glance, the Edge W Power Amplifier exudes sophistication. Its minimalist front panel is a nod to Cambridge Audio's design philosophy of 'less is more.' The brushed metal finish and subtle branding convey a sense of luxury, while the sturdy chassis hints at the quality of components housed within.

Ergonomics and Usability

The amplifier's user interface is intentionally straightforward, with a focus on functionality. The rear panel is intuitively laid out, with clearly marked inputs and outputs that cater to both balanced and unbalanced connections. This ease of use extends to the single set of high-quality speaker binding posts, ensuring a secure and straightforward connection to even the most demanding loudspeakers.

Weight and Size Considerations

Weighing in at a substantial 23.6kg (51.9lbs), the Edge W is undeniably hefty. This weight reflects the quality of its internal components but does necessitate careful consideration regarding placement. Its dimensions, while not overly large for a high-end amplifier, will still require a sturdy shelf or dedicated space within an audio rack.


Class XA Amplification Technology

The Edge W's Class XA amplification is a unique hybrid that combines the best of Class A and Class AB amplifier designs. This approach results in a sound that is both warm and precise, with the added benefit of reduced crossover distortion – a common issue in pure Class AB designs.

Fully Balanced Architecture

The fully balanced architecture from input to output ensures that the audio signal remains pristine throughout its path. This design choice is critical for reducing noise and preserving the integrity of the original recording, offering an audible improvement over unbalanced designs, especially in systems with long cable runs.

Twin Opposing Symmetry Toroidal Transformers

Cambridge Audio's inclusion of twin opposing symmetry toroidal transformers serves a dual purpose: they provide ample power for even the most power-hungry speakers while also canceling out electromagnetic interference. This results in a cleaner power supply and, by extension, a cleaner sound.

Connectivity Options

The Edge W is well-equipped with dual RCA inputs and balanced XLR inputs, catering to a wide array of source components. The inclusion of loop out ports also allows for easy integration into multi-amplifier setups, providing flexibility for various system configurations.

Energy Efficiency

Despite its high maximum power consumption of 1000W, the Edge W is remarkably energy-efficient in standby mode, consuming less than 0.5W. This consideration is a nod to environmental consciousness and the practicalities of cost-saving in the long term.


Power Output

With a continuous power output of 100W RMS into 8 Ohms and 200W RMS into 4 Ohms, the Edge W is capable of driving a broad spectrum of speakers, from the most sensitive to those with complex loads. This versatility ensures that the amplifier can deliver dynamic and authoritative sound across various genres and volumes.

Sound Quality

The sound quality of the Edge W is characterized by its dynamic range and the ability to reproduce fine details with clarity and depth. The amplifier delivers a three-dimensional soundstage that allows listeners to pinpoint individual instruments within a mix. The low total harmonic distortion (THD) ensures that the sound remains clean and uncolored, presenting the music as it was intended to be heard.

Signal-to-Noise Ratio

A high signal-to-noise ratio is indicative of the amplifier's ability to reproduce quieter passages without the intrusion of background noise. The Edge W's impressive >93 dB (ref 1W into 8 Ohm) and >113 dB (ref full power) signal-to-noise ratios ensure that even the subtlest nuances in recordings are audible, enhancing the listening experience.

Comparison with Competitors

In the competitive landscape of high-end amplifiers, the Edge W stands out for its combination of sound quality, build, and innovative features. While there are other amplifiers in the same price bracket, few offer the same level of attention to both sonic performance and design aesthetics. The Edge W's unique Class XA amplification and twin toroidal transformers set it apart from its Class A or Class AB counterparts.

Practical Considerations

Speaker Compatibility

The Edge W's ability to deliver consistent power across a range of impedances makes it an excellent match for a wide variety of speakers. Whether pairing with bookshelf speakers for a compact system or floor-standing speakers for a larger room, the Edge W has the power and finesse to drive them effectively.

Room Integration

The amplifier's wide frequency response and detailed audio reproduction make it well-suited for both small and large listening environments. However, given its power and dynamic capabilities, the Edge W will shine in a space where it can be properly showcased, both acoustically and aesthetically.

Power Consumption

While the Edge W's maximum power consumption is on the higher end, this is typical for an amplifier of this caliber. Users should be aware of the potential impact on their electricity bill, especially if the system is used frequently at high volumes. However, the low standby power consumption does mitigate this concern to some extent.

Final Thoughts

The Cambridge Audio Edge W Power Amplifier is a formidable contender in the high-end audio market. Its strengths, such as the dynamic and punchy sound, low distortion, and high-quality build, make it an appealing choice for audiophiles. While the weight and power consumption are points to consider, they are common traits among amplifiers of this quality and power.

The Edge W's price point positions it within reach of serious enthusiasts who prioritize audio fidelity and build quality. Its performance justifies the investment, making it a worthwhile addition to any discerning listener's home audio setup. For those in search of an amplifier that marries power with precision, the Cambridge Audio Edge W is a compelling choice that delivers on its promise of edge-of-the-art performance.
