1) Buy a few Marantz 7s and 9s and put them away in a closet for 30 years.
2) Buy a Goldmund turntable. I owned mine for 30 years. Of course, 29 of them were spent figuring out how to use it, but man, I loved that thing.
3) Buy season tix at Carnegie and keep upgrading by donating as a patron until you get into the center Tier 1 boxes. That might take 30 years also.
4) Tell your children that if they go near your turntable, you will sell them to buy a new one. It works very effectively.
