You could be surprised how some people get in to the hobby and bring their money to it. I have dentist friend who lives in NYC, and his interests was extremely fair from music and good sound. He was a lot about a cars, travel etc. It was about 10 years ago. We was drinking whiskey at his place and he started crying that his new BMW was vandalized and his luxury car before was vandalized too. I asked him why you keep buying expensive cars if you live in big busiest city it’s just matter of time when it’s will be vandalized again.... he said yah... I earn good money and I want to spend for some good staff and be satisfied... that evening was beginning of his audiophile journey cause I suggested him to invest in good audio gear... he took the advice very seriously.... now he has three top of the notch systems (home, office, summer house) worth a couple hundred of thousands... and he is guru now gives equipment advices to me. :)
