Cambridge Audio Edge A Integrated Amplifier

Redefining Integrated Amplifiers
With Edge A, we took over 50 years of amplifier know-how and challenged ourselves to push the design further. The result is our most accomplished integrated amplifier, made without compromise.
Edge A is built to celebrate musicality, revealing every nuance, every texture, every emotion in your music. It delivers effortless power with breathtaking depth, so you can hear riffs, phrases, and percussive rolls exactly as they were played - just like sitting in the recording booth with the musicians.
Edge A’s gently curved aluminium form, with discreet laser etched logo, single on/off button and centrally located control dial, exudes confidence. It’s equipped to handle a variety of digital and analogue sources, and to output them at a smooth 100 watts per channel. Crafted and tuned by ear, Edge A delivers incredible depth, clarity, and balance. Every component was hand-selected to create an uncompromised listening experience.
Twin opposing symmetry toroidal transformers cancel out electromagnetic interference, delivering consistent tonality and dynamic power at any volume.
Cambridge Audio’s proprietary Class XA amplification eliminates audible crossover distortion, ensuring a pure, natural sound with reduced heat output.
Playback of Hi-Res Audio - up to 24-bit/384kHz PCM DSD256. Built-in high-resolution DAC supports ARC, coaxial, optical, and USB inputs, enabling detailed, high-fidelity playback from digital sources.
aptX HD Bluetooth - Pair any Bluetooth device to your Edge A to easily stream your music. Stream at up to 24-bit/48kHz, maintaining studio-quality sound without cables.
DC-coupled signal path - replaces conventional capacitors, preserving signal integrity and precise stereo imaging across the full frequency range.
Precision-engineered volume control - Solid-state design ensures perfect balance between channels, eliminating the inconsistencies of traditional potentiometers.
Edge A represents the pinnacle of Cambridge Audio’s amplifier design, built with only the finest components selected for their sonic purity. With twin toroidal transformers, Class XA amplification, and a bespoke PCB design, Edge A delivers effortless power and incredible depth, perfectly balanced at any volume.
