Azur 651P

About the Azur 651P

The Cambridge Audio Azur 651P is a phono preamplifier designed to support both Moving Magnet (MM) and Moving Coil (MC) cartridges, providing audiophile-grade amplification with low distortion and noise. It features a single-ended Class A gain stage with passive RIAA equalization using multi-parallel capacitors to achieve exceptional accuracy of ±0.3dB up to 50kHz. The input stages use discrete low-noise transistors instead of integrated circuits to minimize interference and distortion. The unit includes a subsonic filter to remove low-frequency rumble caused by vinyl imperfections, a ground terminal for turntable grounding, and a front-panel power switch to reduce energy consumption. It has two pairs of RCA inputs (one for MM and one for MC), a pair of RCA outputs, and an external 12V DC power supply. The chassis is a full metal construction with a thick brushed aluminum front panel, designed to minimize vibration and interference. The 651P is praised for its wide soundstage, musicality, and detailed, refined output, making it a cost-effective solution for vinyl enthusiasts seeking high fidelity sound.
