Daverz, I heard Quatro many times and never liked 'em. Unlike models 3 and 5 it always sounded "small" to me. Maybe it was a set up. With Vandies Quatro or Five you never know if it's the the way the crossover was set up that you're hearing or the speakers themselves. Anyway, all Vandies no matter what model have a highly recognisable signature sound and I came to conclusion that it's a bad rather than a good thing. Plus as good and musical Vandies are I'm yet to hear them play certain kinds of music well (modern metal for example) while B&W's don't give a flying **** about what kind of music they play - be it Mozart or Slayer, Miles or Eagles, Crimson or James Brown - they don't impose their signature all over it like Vandies do. Now don't get me wrong - I still think Vandies are terrific but simply not the speaker I need now.
