For those of you who had spent over hundred thousand dollars for your sound system.

I can’t afford to spend 150K on a turntable, etc. etc., so I build my own stuff. More fun, and mostly better quality.

Regrets? Didn't start sooner.  DIY forever!!

There must be a lot of wealthy people in this group.  I wonder how you get by the wife factor?  

Either your wife is with you or it comes out of your personal allowance. Fortunately for me, wife is with me all the way - e.g. a higher end Koetsu for a major birthday.

I spy a JJ Electronics preamp in the rack. I had one years ago and still have fond memories of it. Excellent phono stage.

There are several ways to play the wife game.  There is the "sneak": I know someone who bought the cheapest Naim linestage, and when his wife was not home, he then snuck in the top-of-the-line model which looks almost identical to their cheapest model.  There is flat out lying:  I know someone who told his wife he paid $250 for Avantgarde Duo speakers on Craigslist (he got caught when he was updating his insurance information and left the page open on his computer).  And then, there is the most expensive approach of all: the bribe--I know someone whose habit cost well more than twice the price of his gear, because he has to buy some jewelry or other expensive items in exchange for indulging his habit.
