Lottery Winner would buy what kind of Stereo Gear

If you were to win the Powerball or Megamillions what would your stereo system consist of and why?
You meant to say systems, didn't you Rleff? I would set up at least 3 systems, Horns with SET, Ribbons/Planars with Solid State, and Dynamic with Tubes. Certainly each would have it's own custom designed room.
Nothing would change. Why should it? This is a never vending quest. The big leagues just might end up being the minors, though.
"Some of my favorite artists: Sinatra, Miles, Holiday, Rubinstein..."

You can live in the past or explore new artists.

One of the problems lottery winners have is the inability to enjoy old pleasures in the same way they used to. They often wind up less happy. If I had the ability to assemble a "cost no object" system I'm not sure I'd enjoy it more than my relatively modest but personally tweeked system that gives me so much pleasure now.
