Four years ago Audio Analogue celebrated its twentieth birthday with a handful of brand new Anniversary editions of the company's earlier classic amplifiers. Then the brand launched its PureAA line of products, drawing key ideas from the Anniversary amps and adding a raft of further features. Third in the line, following the AAcento amplifier and AAphono, is the new AAdac.

25 years of continuous success, six generations of engineering excellence, and more than a million products sold - these are milestones worth celebrating. The new 600 Series Anniversary Edition is the seventh generation of 600 Series loudspeakers from Bowers & Wilkins. The new range shares the same blend of outstanding value and superlative sound quality as its six forebears but, in Bowers & Wilkins' tradition, features new and improved components to ensure it can continue to set the standard for high-performance sound quality at an accessible price point.
