Product Highlights

    Designed For Purity

    There's something uniquely pleasurable about listening to vinyl, something that digital media can't reproduce in quite the same way. However 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 preamp) 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 we have designed the 551P using premium components chosen for exceptional accuracy, amplifying the signal without distorting it or introducing noise.

Details from Cambridge Audio


    The 551P works with all popular turntables that use a Moving Magnet cartridge (the stylus or needle). For a high–end audiophile turntable with a Moving Coil cartridge see the Azur 651P premium phono stage which works with both types.

    Moving Magnet Vs Moving Coil

    The 551P is a Moving Magnet type (MM) phono stage, which describes the commonly used type of cartridge configuration typically supplied with affordable modern turntables.

    Do I Really Need A Separate Phono Preamplifier

    Some amplifiers are already able to support turntable connections but these in–built phono preamplifiers are massively out–performed by the 551P and we believe that any serious vinyl lover will immediately hear the benefits. Connected using a single audio interconnect cable, the 551P is set up in seconds allowing you to appreciate stunning clarity, musicality and resolution from all your vinyl recordings.
