@dan Honestly, while reading about ridiculous audiophile junk is endlessly entertaining, there is a little part at the back of my mind that knows, for sure, that there is some area of my life where I don't know nearly as much as i think I do, and am completely susceptible to this kind of stuff. And of course I don't know what area(s) they are.
Rob, no, it's not that. You probably wouldn't talk about these kinds of things in-depth, with confidence like that, without researching them first.
