Hmm, I wouldn't go that far. Many people who are not audiophiles still can hear a difference just like non-anime fans can look at an anime and see that Guilty Crown looks more detailed than Puella Madoka, but Kyuubi beats the pants off Gai in terms of sales (so to speak).
I have a pair of Sony noise-cancelling MDR-NC7 headphones too. I mentioned the violins in my prior post because on the MDR-V6, I can clearly tell a mass of violins playing is significantly clearer than on the noise-cancelling headphones where the violins seem like they were "swirled together" to form a uniform muddy mass. Hmm, an example of what I mean to say is: (1) Draw a 6-inch circle on Strathmore heavy tooth reserve watercolour paper. Draw a 5-inch diameter circle on the sidewalk. Draw a 3-inch circle on top of a room temperature chocolate pudding. (2) Take 7 oreo cookies and lay them in the 5-inch circle semi-randomly; this is the Sony MDR-V6. (3) Take 7 oreo cookies, crush them into rough semi-small pieces and put the jumbled up mess inside the 3 inch circle; this is the Sony noise-cancelling MDR-NC7headphone. (4) The 6-inch circle represents my guess for some un-named high-end headphones. Depending on the headphones, I assume the +2,000 USD ones let you hand-pick 9 cosmetically perfect oreo cookies with all the nabisco raised lettering and designs sharp and not chipped or crushed (you get these cookies at the output of the nabisco factory conveyor belt oven and not from a store package). Lay them nicely even and symmetical inside the circle.
