Lottery Winner would buy what kind of Stereo Gear

I'd have two systems: an mbl set-up like in the video (thanks mofi!) in a custom built soundproof room designed specifically for the mbl set-up. I heard that rig at rmaf and it is my favorite stereo I've heard in my entire life. I'd have the room designed by rives audio.

My second system would be whatever comes in a ferrari 458 spider (even though the true music comes with the top down at 9,000 rpm ;-)

Phaelon, super models are good for diffusion, terrible for absorption. Besides, you probably couldn't get them to be quite; "this is like, totally unfair to have to just stand here. Don't they know I'm a super model and I don't deserve to be treated like this."
