I believe the Studio line has 'lesser' cabinetry, mainly in the form of veneer but they still look very nice. UK cabinets seem uniformly well done, esp. with the more exotic woods like yew and burled walnut. The drivers and xover parts may be less highly-specified but those more knowledgeable may have a better answer. Proac certainly has a devoted following, to the point where clones are now available on the web, and even here. Imitation is the sincerest form of flattery.
