Cambridge Audio Azur 840A Amplifier (Certified Refurbished)

Bring true hi-fi authority to your two-channel setup. Cambridge Audio’s Azur 840A uses the brand’s proprietary Class XD output stage to deliver 120W per channel into 8Ω (200W into 4Ω) with vanishingly low distortion and superb control—so you get grip, scale, and detail even with demanding speakers. A massive toroidal power supply, separate pre/power supplies, and a precision relay-ladder volume control keep the signal pristine, while balanced XLR input support and flexible I/O make it easy to build out a serious system.
