I have a box of RtR tapes (Couple hundred on various high-quality Maxell, BASF and other reels) my brother made from vinyl in the early-mid 1970’s. From LP’s I couldn’t afford now in mint condition. But that’s what the tapes sound like now, 50 years on. Mint. The machine I use is a Revox B77 4-track I rebuilt, added upgrades to (digital counter, new input and reproduction boards from Belgium), calibrated it, it’s historic, and brings good memories for me. Fun. What a hobby should be.
