I understand your point, you could also compair it to a mustang gt, 0-60 in 5.5-6 seconds, for 30k or so, then you can get a ferarri for with the same specs for 90-100k. does a home audio system that has $10000 towers sound that much better than my home system?
At the end of the day it is all were you place value, what is the limit for you. I think in the progression of life youstart out by saying why pay $300 for a 12" dd sub when I can get an mtx 12 for $120. then you progress to the DD and say whay pay 600 for an idmax ... until you find your limit. The limit is subjective it think, it is what sounds good enough for you for the money you are willing to spend. If that $100 steak tastes a little better, it is worth the extra money, as long as you value the better taste. What make a Rolex presidential worth $15k does it do any more than my Tissot? nope. but it is worth more.
This is all for conversation sake
