( What loudspeaker is that, my 4" diameter small bookshelves do slightly better than that? )
That has certainly been my conclusion too.
All entirely true of course. I think you have touched on the serious issue wrt to the people who believe they can hear all these non-existent differences which is that they could be spending their money instead on the things that really do make a difference: the speakers and the room. This is the tragedy of it IMO - one can take the view that "well it doesn't do any harm to spend $10,000 on an amp and if they believe they can hear a difference, so what?" - but the real problem is that most people don't have limitless funds, so overspending in one area usually means cutting back in another. And the areas they often cut back on are precisely the areas where a real difference can be made. I despair when I see guys spending big bucks on interconnects and amps and DACs etc and then using them in an untreated room with 'average' speakers. Similarly, I am amused when they then profess to hear 'night and day' differences, despite the fact their room is a nightmare of modal issues, reflections, poor sub and speaker placement etc etc.
The magazines also contribute their share of misinformation too - as you say, they have to 'hear differences' or what will they fill their pages with? I continue to read a fair number of the mags because I like to keep up with what is going on, but do you know, I can't ever remember reading a single article in an 'audiophile' mag (over decades) about the contribution the room makes and how it can be tamed.
You didn't answer Arny's questions...
Er... he asked you if you had specific examples of $1,000 and $10,000 amps in mind when you replied what you replied, and he asked you if you had any evidence to back up your assertion that the speakers 'wouldn't sound very good'. So do you?
