Excellent glossary! Thanks for the link.
IMO, writing about sound is like writing about food (a clever chap said writing about music is like dancing about architecture...). A food critic can talk about the various flavours of a dish in a way that can leave you salivating (or disgusted); but until you taste it for yourself you will never know whether the dish is for you. Tart, sour, sweet, smooth, crunchy, creamy, pungent, light, gamey, fluffy, brittle, juicy, melt-in-your-mouth: all of these words evoke reactions based as much on chemical and emotional memory as any objective description they aim to build. But they say as much about the reviewer as about the dish itself.
Similarly, we can agree to use the terms in the glossary, but there's no way to tell whether the headphone is something that you as the individual listener will actually like. Warm, lean, bassy, harsh, neutral ... see what I mean? Maybe you'll agree with the reviewer -- but maybe not!
Anyway, another clever chap said I don't know art, but I know what I like. Listen to the V6 (or 7506) in a test with other Sony MDR's and you'll know whether Gautama's statement is true (for you). BTW, it was for me, for what that's worth.
Man, this post doesn't help, eh?!?
