Mark Fleischmann has posted a review of the B&W 805 Diamond Series loudspeakers system (together, $14,500), including a full suite of measurements, at Home Theater. His conclusions:
The Bowers & Wilkins 805 Diamond provides the high-end sophistication of the Diamond Series in a monitor package that’s especially well suited to home theater (and that certainly includes music). This speaker’s top-to-bottom confidence is the product of a good ear, first-class engineering resources, and top-flight materials. It also has an artistic prowess, an ability to juggle disparate elements that made each new listening experience unique, often sur- prising, and as pleasurable as the source material could support. The HTM4 Diamond center is equally worthy, and it’s not often that I can say that about a center speaker. The ASW 12CM sub complemented the Diamonds with an ideal mix of power, restraint, and adjustability. No question about it: This is an expensive system. But worth it.
