I do apologize - I am replying before reading the whole thread - conversation might have moved on and I am so dumb that can't find how to multi-quote
1.- Kind of joking but not really - the "enlightened" in the original post? I wouldn't have call them that!
2.- Regarding the quote above, +1 - I think I have come up with a simple analogy for this - for most anything, if you spend A LOT OF MONEY for, let's say a widget, more or less, your are getting something good. That is, by spending money, your are avoiding having to be informed with actual research (not marketing spiel)... knowledge in a way...
BUT
The sign that you know your stuff is when you spend, let's say (and this is just something I just pulled of my BBB ) 10% of the price for 90% of the performance. For many devices being an engineer definitely helps with that. And on top of everything, in audiophilia, given we are dealing with subjective opinions tied to the very fallible human ear... I think the threshold is amazingly low. $100 will get you 99.99% of the performance!
