I don't begrudge anyone with the means to pursue the ultimate.
That said, I can't help but wonder whether it's not true that "ignorance is bliss".
I can be very obsessive and am not at all sure that being exposed to 100K systems would make me happier, knowing I could never afford one, myself.
Furthermore, as I'm not engineering-minded, were I able to spend 100K, there's no guarantee I'd end up withy a system that I'd enjoy more than my current 25K system.
I actually haven't heard many systems. I attended a couple meetings of a local audiophile society and felt very out of place, as the emphasis was very much on gear. No-one wanted to talk about music.
