Good point. I remember much earlier in my pursuit of high end audio being very happy once my system was in place that I got years of pleasure at no additional cost (not including record collecting). I would go many years 5 - 10 without any investments.
My system cost is about double what it has been since my retirement. But if I just consider the incremental $75K I put into my system since I retired (earlier investments well amortized) and that I listen about 1,100 hours a year… assuming I live at least another 10 years… That’s about $7 / hour. My season tickets to the symphony are about $70 / hour. Or $35 / hour if only one seat.
Of course I have custom made bicycles.. those are about $2 / hour. I ride about 5,000 miles a year.
