In 1966, John Bowers and his friend Roy Wilkins established B&W Electronics Ltd. -- the seed money had come from an elderly lady who’d been deeply impressed with Bowers’s knowledge of classical music and the quality of the speakers he’d built for her. The same year saw the development of B&W’s first loudspeaker, the P1. Now, 50 years later, Bowers & Wilkins has grown into one of the world’s best-known loudspeaker brands, with a huge variety of products and a distribution chain that spans the globe. Its 50th year saw the redesign of B&W’s flagship 800-series speakers, and the introduction of their first flagship headphones model: the subject of this review, the P9 Signature ($899.99 USD).
