Tekunda, you pose an intriguing question, "How can opinions on sound quality differ so much?" Of course it depends on one's listening biases, his/her individual hearing curve, and familiarity (like or disdain) for the particular music being played. Even one's own past listening experience comes into play. I think folks tend not to like presentations that are radically different from what they hear from their personal systems, even if the radical differences are for the better. Having attended my fair share of audiophile demonstrations, I know, first-hand, that it is not uncommon for 'philes to totally disagree on whether what they have heard was good or bad. Interestingly, they usually agreed on what they had heard -- but some would like it and others would not. I used to say that if musicians were playing live behind a curtain, that half the audiophiles in the room would swear that the sound was totally unnatural and inaccurate. It seems to be the nature of the beast.
The only reason that I even posted about the MBLs was because the other fellow who posted insisted that they had the "worst" sound at the show. That just seemed too far left of center for me to ignore. If he had merely said he disliked them I could have let that lie. But he is entitled to his opinion -- as are we all.
Even if there were such a thing as a "perfect speaker," there would be those who would insist it was flawed and not to their liking. Of that, I am entirely certain. :)
