Cambridge Audio MXW70 Power Amplifier

Mighty Musical Muscle Meets a Compact Footprint

Musical muscle meets a compact footprint. The Cambridge Audio MXW70 amplifier adds power and refinement to any setup, driving even difficult speakers without the bulk of other power amplifiers.

Designed and engineered in London, the MXW70 is the ideal companion for Cambridge Audio's award-winning MXN10 music streamer with digital preamp mode. Together they form a half-width, high-performance streaming system that fits seamlessly into any space and can be fully controlled from the StreamMagic app.

Don’t let its size fool you. The MXW70 boasts an impressive 70 Watts (at 8 Ohms) of refined stereo power per channel, capable of driving even the most demanding speakers without the bulk of traditional power amplifiers. With a simple switch, you can transform the amplifier from stereo to mono mode, unlocking a staggering 250 Watts of bridgeable power.

Carefully Tuned by Expert Audio Engineers

Since the introduction of the groundbreaking P40 amplifier in 1968, Cambridge Audio has crafted iconic sound in the UK – and the MXW70 is no exception. Designed, engineered and built at the company's London HQ, it delivers emotive sound with exceptional clarity, resolution and musicality.

Driven by Hypex NCORE Class D amplifier technology and carefully tuned by Cambridge’s expert audio engineers, the MXW70 offers high efficiency and compact size while maintaining the musical sound quality that Cambridge Audio is known for.

Comprehensive Connectivity

The MXW70 features both RCA stereo and studio-quality XLR inputs, giving flexibility in how it integrates into your home audio system. Whether you’re powering a stereo setup or home theater, you can do so with the knowledge that the transmission signals will be noise-free. Standard 4mm banana plug sockets with binding posts make it easy to connect any type of speaker.

Thanks to its 12v trigger input and pass-through, the MXW70 also simplifies day-to-day use by enabling automatic power switching for connected devices. A USB adapter cable is supplied for auto power on/off when using the MXN10 as a digital preamp – use the StreamMagic app to remotely turn your streamer on and the MXW70 will start up too.

The Perfect Partner

Extending the half-width audio experience even further, the MXW70 can also be partnered with the award-winning DacMagic 200M DAC to result in a system with a physical volume knob, a range of digital inputs, and a high-resolution headphone output.

But the flexibility doesn't stop there. With its compact, discreet design, the MXW70 can be slotted into almost any setup – even with one MXW70 used in mono mode for each channel of a powerful home theater system.

Minimalist, Timeless Design

Premium, all-metal casework creates a minimalist, timeless design that’s flawlessly finished in Cambridge’s trademark Lunar Grey to match MXN10 music streamer and DacMagic 200M DAC.

With all the power and features of a full-sized power amplifier but measuring just 8.46" wide, the MXW70 is small yet mighty. This compact size means it can conveniently sit on your desk, in an entertainment unit, or hidden away.

The MXW70 redefines the possibilities of compact audio solutions, blending powerful performance, versatile connectivity, and elegant design.
