I do have to point out that there can be a real link between cost and performance, not always as dominant or determining, but it is there. For instance, I completely agree with the sentiment the above poster advocates for, but I also would point out that the gear listed is very expensive so the idea that they will be more than just a price tag as articulated certainly is true, but there is an element of getting to that stage by affording the more expensive gear. I have come across people that eschew the idea that expensive gear is better, and even when they can afford top of the line gear, they actually find their preferred sound signatures in lower cost items, but those people are rare. I do think that typically people purchase the best that they can afford or rationalize.
