What we MUST have in mind is that many manufacturers speculate with tha fact that most of their clients listen to live music hardly ever. Their idea of how acoustic intruments sound differs from the truth. Many "high end" systems sound more surreal than realistic.
Also a good point. I think this goes back to the surround sound argument as well - how many movie-goers are involved in impressive car chases or fast-paced shoot-outs in their daily lives? Let alone exposed to things like dinosaurs, vampires, alien invaders, and monsters from hell?
So do you go for "cool" or "accurate" in this case?
