About the Azur 551P
The Cambridge Audio Azur 551P is a dedicated moving magnet phono preamplifier that allows vinyl enthusiasts to connect their turntables to standard hi-fi amplifiers that lack a built-in phono stage. It amplifies the very small signal from a turntable's MM cartridge to a level suitable for main amplifiers without introducing distortion or noise. Designed with premium components including discrete transistors and audiophile passive RIAA equalization, the 551P delivers a warm, detailed analog sound. It features an acoustically damped full-metal chassis with a thick brushed aluminum front panel for durability and reduced interference. The unit supports all popular MM cartridges and offers a gain of 39dB, a signal-to-noise ratio greater than 85dB, and very low total harmonic distortion (<0.009%). It is powered by an external power supply to minimize noise and has a compact footprint. The 551P is ideal for serious vinyl lovers seeking clarity, musicality, and resolution from their records.
