Product Description:
Musical Muscle, Compact Footprint
The MXW70 brings serious power and refinement to systems where space is at a premium. Designed to deliver authoritative amplification without the bulk of traditional power amps, it comfortably drives a wide range of speakers while maintaining control, clarity, and composure. Whether used as a stereo amplifier or bridged into mono, the MXW70 proves that compact dimensions need not limit performance.
Power Aplenty
Despite its modest size, the MXW70 delivers 70 watts per channel into 8 ohms, increasing to 125 watts into 4 ohms. When configured in bridged mono mode, output rises to an impressive 250 watts into 8 ohms—making it suitable for more demanding loudspeakers or mono-block configurations.

Super-Compact System
Paired with the MXN10 Music Streamer, the MXW70 forms a complete half-width streaming hi-fi system with minimal footprint and maximum performance. Adding the DacMagic 200M further enhances digital clarity while introducing high-resolution headphone listening, creating a flexible, modern compact stack.
Designed In London
Engineered by Cambridge Audio in London, the MXW70 is meticulously tuned to deliver high-fidelity sound from a remarkably small enclosure. It integrates effortlessly into existing systems or serves as the foundation for a minimalist modern setup.
Hypex NCore Class D Amplification
The MXW70 uses Hypex NCore Class D amplification to provide smooth, dynamic sound with excellent efficiency. This advanced topology ensures low distortion, high damping factor, and consistent performance across a wide range of speaker loads.
Compact Footprint
At just 215 mm wide, the MXW70 fits easily on a desk, inside an entertainment cabinet, or discreetly tucked away—without compromising output or sound quality.

Wired For Sound
Connectivity includes high-quality speaker terminals, stereo RCA inputs, and balanced XLR inputs for studio-grade signal transmission with superior noise rejection. A 12V trigger pass-through allows seamless integration with larger systems.
Full Metal Jacket
Built without compromise, the MXW70 features premium all-metal casework finished in Cambridge Audio’s signature Lunar Grey. The minimalist design complements modern interiors while ensuring mechanical rigidity and long-term durability.
