CAMBRIDGE AZUR 651P/B PHONO ST

Love vinyl? Make the most of any turntable, including the most high-end audiophile models

Adding a turntable to your system is like having a log fire - a radiator may warm you up but you wouldn't want to sit and watch it. There's something uniquely pleasurable about listening to vinyl, something that digital media can't reproduce in quite the same way. While the latest digital formats sound incredible, there's detail and warmth that can't always be expressed in 0s and 1s, crackle that adds character, and live music simply comes to life. And the Azur 651P makes the very most of vinyl, whatever your deck. It even works with Moving Coil cartridges found in the highest of high-end audiophile turntables.

In more detail

Most hi-fi amplifiers won't let you plug in a turntable directly. You need to connect via a phono stage (also known as a phono pre-amp) to make the very small signal from the turntable powerful enough for your main amp to work with. But it's very easy to add noise at this stage, which is why our audio-obsessed engineers carefully designed the 651P using premium components chosen for exceptional accuracy, amplifying the signal without distorting it or introducing noise. They've fine-tuned every element to perfect the performance, creating a state-of-the-art phono pre-amp.

In fact, the 651P does its job with such finesse that, even if your amplifier does have a built-in phono stage, it's well worth bypassing it, bypassing it using the 651P is guaranteed to deliver much greater depth and detail of audio. Vinyl lovers will instantly hear the difference that the dedicated 651P makes to music quality.

The 651P works with all turntables, whichever type of cartridge they use. Like the 551P it works with popular Moving Magnet cartridges. But it also works with Moving Coil cartridges found in the highest-end audiophile turntables.

To those who wrote off vinyl as "dead", we say "nonsense"! Vinyl is once again rightly growing in popularity for the audio quality and particular warmth it can deliver. The Azur 651P, developed in London by our team of music-loving perfectionists, truly makes the most of your vinyl.

Moving Coil compatible

Works with Moving Coil, the audiophile's cartridge of choice, offering even more accuracy and detail than Moving Magnet.

Advanced amplification

Audio circuitry has been refined with multiple transistors wired in parallel ensuring the lowest possible distortion and noise. A copper shield provides further protection to this extremely sensitive part of the circuitry, limiting the noise that can be injected into the signal. This is especially important with a Moving Coil cartridge because its signal is even quieter and more delicate than Moving Magnet, so it needs even more amplification.

Premium components

High-spec multi-parallel capacitors achieve exceptional RIAA accuracy - the industry standard for reproducing vinyl recordings. While a highly accurate, subsonic filter removes the common problem of unwanted low-frequencies that are inaudible but can damage subwoofers.

Total power off

In line with Cambridge Audio's commitment to the environment, a power switch cuts energy consumption to zero when not in use.
