For years I have been hearing about how our musical libraries are vanishing, yet to this day I have never met a fellow audiophile without one.
Perhaps it's my limited exposure to other audiophiles but I rather think not.
Instead, I'll bet the bulk of you still have collections of physical media. I certainly do. Rows of albums and piles of CDs and SACDs.
What I think has changed is not the presence of physical libraries, but rather a decline in their use. Unless I am working on a specific project where I need an absolute known reference, I am more likely than not playing it from Qobuz.
So, I don't think libraries are obsolete. Not for a long time.
I do believe their use is declining.
I for one would feel rather naked without my surrounding collections of physical media.
How about you?
