I'm transferring three of my four complete Ring Cycles to MP3.

[Aristus]

I've got the Ring by Georg Solti and the Vienna Philharmonic, the English Language Ring Cycle by the English National Opera, and the 2013 Seattle Opera Ring Cycle. Even on CD, they're awfully cumbersome to transport, so I got a new Apple device just for my Ring operas. They're uploading right now.

My fourth Ring is on LP. It's a very poor recording of the 1951 Ring Cycle at La Scala, notable mostly as one of Kirsten Flagstad's final performances as Brunnhilde.

1. Put them on your computer as flacs...

then you will have them "uncompressed". Then you can do whatever you want with them for easy transport.
