I don't think that's a comparable analogy though. Creating music (guitarist obsession with tone) is very different from listening to a particular genre, just because it sounds "good". Yes, you might buy different guitars and amps for different styles, but I wouldn't start playing jazz because my amp had a good jazz tone, but then I don't buy hifi gear specifically because it's good at one genre, it should be good for everything if it's good enough. As it happens, I have a pretty wide range of musical taste anyway, that does include Jazz; but I don't think my set up is better at any particular style, it's good at presenting all styles that I like to listen to!
