Cambridge Audio Azur 840C CD Player Balanced Outputs

The Cambridge Audio Azur 840C is a high-end CD player and digital hub built around a dual differential DAC architecture using twin Analog Devices AD1955 chips, combined with Cambridge’s proprietary Anagram ATF upsampling to 24-bit/384kHz. It features a fully balanced design with XLR and RCA outputs, plus multiple digital inputs (coaxial and optical), allowing it to function as an external DAC. Internally, it uses multiple regulated power supplies (up to ~19 regulators), high-quality capacitors (often Nichicon-based), and a robust linear power supply, contributing to low noise and stability. The transport is solidly built, and the unit offers wide connectivity including digital outputs, control bus, and RS232, making it unusually versatile for its era.

Sonically, the 840C is widely regarded as a “giant killer” digital source, combining high resolution with smooth, non-fatiguing tonality. It delivers excellent detail retrieval without midrange glare or harsh treble, maintaining a rare balance between precision and musical ease. It is tonally neutral with strong timing and rhythm, presenting music in a controlled yet engaging manner rather than sounding overly analytical
