What audio standard do you play or collect?

My everyday choice is Streaming. But I still have my 300+ CD collection collecting dust out in the barn. I used to and still prefer old Jazz and blues on original vinyl.

Currently I stream through Spotify and my brohter’s iTunes account.

CD to Digital FLAC.

Exactly, when ripping CD you should use FLAC.
I remember old mp3-Players could not play this format.
