This is audio conspiracy theory to the max. The thought that well known audio manufactures' business model is to fool their customers so that they will buy a product they won't like and have to trade up sooner is borderline paranoia. THE PROBLEM: is that a vast number of audio buyers, even high end buyers, don't know how to listen or know what to listen for or just don't know their audio tastes so they end up making mistakes. That's not the manufacturers fault.
Are audiophile products designed to initially impress then fatigue to make you upgrade?
If not why are many hardly using the systems they assembled, why are so many upgrading fairly new gear that’s fully working? Seems to me many are designed to impress reviewers, show-goers, short-term listeners, and on the sales floor but once in a home system, in the long run, they fatigue users fail to engage and make you feel something is missing so back you go with piles of cash.
