@mijostyn Thanks for the list! One or the early upgrades I thought about was putting a Jico SAS/B stylus into my Shure V15, which I guess is 50 years old and has an elliptical stylus. For about the same price I bought a new Audio Technica VM540ML cartridge, which seems to have the same MicroLine stylus as the SAS/B, albeit on an aluminium cantilever. It makes it on to TAS' "50 Greatest Bargains in High-End Audio". And I still have the complete Shure cartridge!
Had not thought of digitising my records, though I did record all my dad's records to tape. I note that Presto Classical can now singly manufacture no-longer-available CDs from the back catalogues of record companies like Decca, Deutsche Grammophon, Philips, Sony etc. They also had over 6,000 SACDs in their catalogue last time I counted. And they have just introduced a streaming service including file downloads.
