Cambridge Audio Edge M Mono Block Amplifier

Cambridge Audio Edge M – Reference-Grade Mono Block Amplifier

The Cambridge Audio Edge M is a reference-class monoblock amplifier crafted for audio purists seeking uncompromised performance and effortless power. Built with absolute attention to sonic purity, the Edge M delivers dynamic clarity, breathtaking transparency, and precise control over even the most demanding loudspeakers. Designed as a single-channel powerhouse, it features minimalist signal paths, custom toroidal transformers, and premium components throughout.

Whether anchoring a two-channel reference system or driving high-end speakers in a home theater setup, the Edge M offers pure, articulate performance with warmth, impact, and holographic detail.

 Sonic Excellence with High Power Output

 200W into 8Ω / 350W into 4Ω – Delivers massive clean power with tight grip and exceptional dynamics, ideal for full-range floorstanding speakers and reference monitors.

 Class XA Amplification – Operates in Class A at low levels and transitions seamlessly into Class AB for higher output, reducing distortion while maintaining efficiency and warmth.

 Ultra-Short Signal Path – Simplified circuitry with fewer than 14 components in the signal path ensures minimal coloration and a direct, transparent sound signature.

 Dual Toroidal Transformers – Specially wound to reduce magnetic interference, delivering ultra-clean power and superior channel separation.

Inputs and Outputs

 1 x Balanced XLR Input – Ensures ultra-low-noise signal transfer from high-end preamps or DACs.

 1 x Unbalanced RCA Input – Compatible with most stereo preamps or integrated systems.

 1 x Balanced XLR Loop Out – Allows daisy-chaining for bi-amping or complex system integration.

 1 x Trigger In / 1 x Trigger Out (3.5mm) – Enables remote power control from other components or system controllers.

 1 x RS232 Port – For integration into control systems.

 High-Quality Speaker Terminals – Accommodates spade, banana, or bare-wire connections with rock-solid mechanical grip.

 Build & Engineering Highlights

 Solid Aluminum Chassis – Thick, vibration-damped casing with high-grade materials throughout for resonance control and visual elegance.

 Symmetrical Mono Design – Each Edge M is purpose-built as a mono amplifier, eliminating crosstalk and maximizing signal integrity per channel.

 Precision-Milled Heatsinks – Sculpted fins on each side act as passive cooling without fans, maintaining optimal thermal performance and silent operation.
