I listened to vinyl LP, shellac 78s and R2R tape. By 21 years old (1977), I had 10,000 LPs, 3,500 78s and 150 R2Rs, mostly self recorded from LPs and FM (Met Opera). My collection doubled by 35 (1991) except for the R2Rs. Then I added CDs, now at 7,000 with over 1,200 in box sets/collections. I kept buying LPs and 78s until today. I sold 18,000 78s and LPs over the years as I have a rule, if I don't potentially want to hear a recording 3 times annually, out it goes.
