I listened in my teens to the one from the library that had Nilsson in her Valkyrie outfit on the booklet. I can't remember which one that was. I heard from the seller that someone famous signed my Gotter..... booklet. Please Please be Nilsson!!! I listened to Nilsson's Siegfried duet from the Time Life Series and her voice sounds much better on vinyl. I also perused and bought a Beethoven Complete Symphony set by Toscanni from the Masur private library collection. i am stoked.You're bringing back nice memories of acquiring the Solti Ring in my teens (omitting the Walkure, for which opera I preferred the Leinsdorf recording in RCA's magnificent Soria series). I have to say that life has been downhill ever since.
