Apparently, you haven't been the thread closely. It has been explained many times that amplifiers (or anything) that is made from expensive parts and materials by skilled labor in very small quantities is costly. Those who make these items want to make a good profit from their efforts, as do the distributors and retailers.
No one is "misleading" anyone, and just because some can afford and want to buy these products does not make them "gullible".
I don't anything that can be supported in your comments.
