Here is a recording of the Bowers & Wilkins 702 Series 3 speakers playing Vogue by Madonna at Audio Video Therapy. Please use headphones to reproduce the binaural audio. Enjoy!
Having returned my s2 after 90 days (have to love Best Buy) for the s3 I can say the differences are subtle but appreciable. The biggest selling point for me was the new design/form factor, especially the plinth. If you can afford the s3 they’re worth the premium.
Sorry, but I don't believe there is one brand the best. Allot of brands are good. It is just the taste of the person what sound they like, and what brand comes close to there whishes. So dynaudio is s very good brand like bowers and Wilkins and like Klipsch and so on
