CAMBRIDGE AUDIO AZUR 650A

Pre owned. In good conditions. Shows light signs of wear. Supplied with remote control (worn, as shown in the photos, but fully functional). Does not include original packaging.

The Cambridge Audio Azur 650A is an integrated amplifier that combines preamplification and power amplification functions in a single chassis, offering a complete and high-level solution for discerning music enthusiasts. From the very first glance, it impresses with its elegant, modern, and minimalist design, featuring a brushed aluminum front panel and a rigid, seamless monoblock chassis designed to reduce resonance and enhance structural integrity. The dual-layer damping feet not only provide stability but also contribute to excellent mechanical isolation.

Internally, the 650A stands out for its superior engineering. It features an oversized toroidal transformer, twin rectifiers, and separate power supplies for the left and right channels, enabling true dual-mono operation with extremely low distortion and an impressively dynamic sound. The fully redesigned output stage delivers tighter bass response and remarkably fast, controlled drive over any type of speaker. Channel balance is handled by a high-quality ALPS volume potentiometer, complemented by refined tone controls that allow precise adjustments to bass and treble without compromising sonic purity.

Each internal component is carefully selected—from strategically placed electrolytic capacitors to audiophile-grade polypropylene capacitors. Gold-plated speaker terminals ensure the cleanest signal transmission possible. Cambridge Audio’s proprietary CAP5 protection system constantly monitors the unit for overloads or faults, ensuring safety without interfering with audio performance.

In terms of connectivity, the Azur 650A is equipped with a wide range of options: analog RCA inputs for multiple audio sources, a dedicated phono input for turntables, and a convenient front-panel input for portable devices like iPods or MP3 players. A headphone output is also included, as well as rear speaker terminals. The amplifier integrates seamlessly with modern digital systems such as Apple TV, Sonos, or Squeezebox, and can enhance the sound quality of TVs or DVD players.

With the included Navigator remote control, users can operate the amplifier from a distance, as well as control matching CD players such as the 550C or 650C, or even an iPod connected to a compatible dock like the iD50. Every aspect is designed for maximum convenience, without compromising performance.

The Cambridge Audio Azur 650A is built to be a true benchmark in its category—an amplifier that blends power, precision, refinement, and versatility in a single unit, created for those who want to experience music with the highest level of immersion.
