Perfect sound Now what?

I don't know about you guys, but the amount of thought, time and money that I devote to this hobby/quest can hardly be called insignificant. Let's assume, pretend might be better, that perfect sound is actually achieved. Bose does it! They crack the code and give us perfection... on the cheap (I never promised this wasn't going to hurt a little). What would you guys do to fill the void. What activities would you pour your considerable, newly found, disposable income time and effort into? I think I'd like to give photography a whirl. Maybe build an ultralight plane. Ever give this any thought?
