You are however making a mistake here. I never asserted that it is like I said and that it is the absolute truth. I am sharing point of views and experiences which are clearly described as sighted and not controlled.
Also, the quote is not the most brilliant thing by Christopher Hitchens – if one asserts X without evidence, his assertion act can be dismissed without evidence. Not X itself, which may have supporting evidence independently. Of course if X is not only asserted, but it is also claimed that evidence is not necessary and, as in religion, even detrimental, well, then it is clearly bollocks
The challenge in post #74 is clearly for amplifiers within parameters that do not stress them - for the anecdotal phenomena I was mentioning you need to bring the amps to stressing them.
Since I switched to high efficiency speakers I doubt I will ever stress my amps in any way, so I do not think I would be able to perceive any difference.
