The issue is...once a typical audioboo snob goes up in price, he will never look at anything cheaper lest it beat his high price junk, somehow. So, you will never get a fair comparison, feel for what you get as you go up in price on a speaker in the same room with the same electronics.
For example, there is the question of at what point is a speaker just getting carried by the electronics? A guy will put a 15k or 5k speaker on 10k, 5k, etc cheaper electronics, a 60k speaker on 40k electronics and so on. He will never give that 15k speaker or a 5k speaker the same chance (i.e put both the 60k speaker and the 15k speaker on the same 40k electronics). And then, he'll claim that the carried 60k speaker beat the 15k speaker or 5k speaker. When you level out the playing field, "interesting" results emerge.
It you are in the KC FB group, swing by for a demo/comparison of gear at drastically different price brackets (see what you get as you go up in price or not), some good ol' fashioned myth busting and acquisition of 'disruptive' knowledge.
