Primarily the biggest difference is that generally the Germans are much more serious about hi-fi than we are and also tend to spend big money on seriously hi-end kit.
They tend to think more 'out of the box' than we do and in terms of equipment are not afraid to go outside of the mainstream, whereas in Britain enthusiasts, in the main, are 'bargain hunters' who operate in the low to mid echelons of the marketplace buying mainly mass-produced mainstream hi-fi.
Basically, outside of the US, the Japanese and German markets are where the 'big players' are in hi-fi, so the Munich show reflects this.
