My first brush with high end audio was hearing a high school friend dad's system. It was an AR turntable, Shure cartridge, AR 3 speakers and the AR receiver. At the time this was a very popular combo and it sounded great. However, when I got to the point where I was actively putting together systems I took it as axiomatic that mixing and matching brands was the preferred method. Thirty some years later I'm not so sure. One size will never fit everybody and great results can be achieved either way, but I now believe that for most people (especially music lovers) that it's easier to attain quality sound by going the single brand route. Going with a single brand isn't very different than trusting yourself to a good dealer. Tell them what you want to achieve and how much you have to spend and then let the dealer/manufacturer come up with their solution.
I'm not sure I agree with the thinking that specializing in a component type really produces better quality. At the cutting edge of state of the art components it's probably true, but for more real world products I don't see a correlation. Linn was originally famous for their turntables, but they quickly started to produce some good speakers and later on some top rank CD players. Most people know Quad for their ESLs, but they have always produced very high quality amplifiers. I think it's just a question of a company having the capital to hire the expertise in those areas were they want to produce products.
I don't know why there appears to be a European/U.S. split on this issue. It could just be a historical quirk.
