I was fortunate to spend much less than $50k on my Apogee speakers, which may perform as well as some $50k speakers.
I was also fortunate enough to buy a $50k Hyundai Ioniq 6 for only $40k after the manufacturer's multiple rebates (in 2024). It comes with free maintenance for 10 yrs. and free charging for 2 yrs., so it was not hard for me to buy it and sell my 27-year old Camry. It even has a listenable "premium" sound system, but the best thing is that the car is quiet enough to listen to even classical harp while driving on the freeway.
