Yes, you are correct, I am assuming most all content is available. Most is. However, what happened to me, and I suspect what happens to most folks is that once the sound quality difference disappears and you have access to more than a million albums your focus shifts from playing the really restricted amount of music you have collected… carefully chosen to sound the very best because of it’s high cost, to exploring new music, enjoying thousands of albums you never knew existed.
When my streaming sound quality rose to my other sources, I think I called up the albums I owned for about a week, before I noticed an album I had never heard before from the same group while searching. Then I would remember a band I did not own. Then I started to just look at new albums, then choose genera and listen to new stuff. Very quickly I seldom would listen to the old stuff I owned. And when I did, if it isn’t there, there is a high definition version of one of their other albums or a better band.
High quality streaming changes everything.
