Cambridge Audio 551P Phonostage – Black

Here we have a well-regarded budget phono stage from British based company Cambridge Audio. The Azur 551P offers input for moving magnet cartridges and our unit is in very good condition, noting a small blemish on the top – please refer to photographs. It is supplied in original factory packaging along with power supply unit, manual plus our normal three month warranty.
Cambridge Audio Say….
Like all Cambridge Audio products these phono pre-amplifiers adhere to three core principles – stunning performance, ease of use and incredible value.
The design of a high quality but cost-effective phono pre-amplifier presents a major challenge. Providing first-class performance on an unlimited budget is one matter; achieving the same performance within tight price limits is quite another, and requires all the expertise and experience that Cambridge Audio brings to its product design process. We believe we have succeeded in our aim of creating a first-class affordable product.
The 551P features a moving magnet stage and uses low noise discrete transistors for the all-important input stages instead of the more common integrated circuits.
Designed to produce high gain and linearity, without requiring massive amounts of negative feedback to achieve low distortion. It also employs a single-ended ‘Class A’ gain stage with audiophile passive RIAA equalisation.
High quality components are used throughout such as 1% metal film resistors and close tolerance polypropylene capacitors.
