There was a story in a High fidelity magazine
Do you remember what year was it? Perhaps, it is possible to find the article.
I could not tell you, it was in the 1980s, and I do not even remember which HI-FI magazine it was in, I read several back then.
It is a subject that has been covered by many in different ways though, I seem to remember a similar one using a new tube amplifier that was extremely expensive, Like 10,000 dollars for a hundred watt amp that would normally be under $1,000. People act this way still all the time, thinking that they can hear the difference, but when subjected to vigorous blind tests they cannot tell the difference, sometimes there is hardly a difference in the specifications when tested side by side . That is not to say that there are not differences in some cases, just that people tend to hear what they want to hear.
