Valueless? Is that even a word?
Does one have to drive a Lamborghini to know that they are some of the finest automobiles in production today?
It would be nice if we could audition all the high-end equipment discussed here but that is just not possible.
Opinions are formed on personal tastes , reviews, and here-say. Like you, I know a quality product when I see one. Take Playboy magazine for example. I can certainly appreciate the beauty of the young ladies pictured but chances are slim to none I will ever met meet them in person. That does not prevent me from forming an opinion on what I see and read. Just like theses beautiful women most High-end gear is way out of my league, not to mention price range.
We can dream though.
