If you won the power ball tomorrow night would you

Zoya, even this kind of money cannot help in inviting dead musicians. Besides, musicians are not servants. I mean, not supposed to be, they should not come to your house.

i can tell you right now that the ones who went out and spent 400k on a new set up would never be happy with it after a week. i would wager they were back on a gon 10 days later looking for tweeks, like that resonator bell i see for sale at 2400$. best bet is season tix for every major symphony and concert you can find

Veroman,

So true.

"Hey, devil, ,I already have a sense of humor , You need a sense of serious."

Yep, you seem like a true comedian schubert...

I am frugal:

1- Re-tip my Supex through SoundSmith. Find an Audire Class A amp or two, eventually; otherwise, go to Audio Research. Buy back my beautiful KT-917 or equivalent. Keep B&K tuner. Upgrade B&W 803's with 802's. Build perfect sub box for inside my fake fireplace. Take audio design course at MIT to design crossover for such and my DM 16 based subs. Well, maybe hire consultant from MIT, instead.
2- Get rid of Supercharged S2000 and its crappy sound for supercharged Lotus Evora with whatever it takes for great sound. Add Jag XKS convertable for daily driver.  
3- Undoubtedly, but maybe just add on to house. Already have excellent acoustics, but garage could be redone into third system, maybe even with movies. A second floor would be nice. A new system in my repurchase of ex-chalet in the mountains would be on the list. 
4- NOOOOO!
5- Mostly, and I don't have to win the lottery.
