If you won the power ball tomorrow night would you


1. Upgrade parts of you're system.
2.  Get rid of everything you have and start over again.
3.  Buy a new house and build a dedicated listening room.
4.  Hire a consultant to put together a system for you.
5.  Just enjoy what you have and buy more music.

1. Buy presidency. Not US presidency.
2. Slightly improve my stereo, by a factor of 10.
3. Not a dime to any charity, might set-up my own.
Alternatively, could sacrifice the presidency and stereo upgrade, form private Foreign Legion and stop the war in Syria within two months. Doctors Without Borders and Save The Children wouldn't be needed there much.
Don't wanna sound like a jerk here but, charities will not be the first thing I think of if I hit for 1 billion dollars. 
All this "doctor's without borders" talk is NOT why I'm reading this thread.
Come on guys. Say something....
...I don't know.......exciting. Remember, you just hit for a BILLION dollars.
After/if I made it through the first few weeks of partying like the wolf of wallstreet, then I'll start to think about charities. 
If I'm not dead. Lol

Definitely #3. This is the plan already established. If I had that sort of money however the "room" would be a separate building from the main house connected by a breezeway. I would research and oversee each step of the construction since I love projects. The most interesting aspect would be determining room shape. That would be so much fun!
