@mikelavigne first post says it all.
And one can make setup simple or complex, spend a lot or not so much. You can get damn nice sound quality with lower expenditures, spending more gives marginal increases, and then one may get past this certain plateau of marginal increases to where sound quality goes into revelatory territory.
I have well over 3.5k physical cd media, around 3.5k vinyl and even with this relatively large collection streaming has so far much more to offer, I've found SO MUCH new wonderful music! I'd have to spend multiples of $10k on physical media to match whats in my streaming libraries. And I can play all this music in stream of consciousness mode, I love all genres of music and playing a particular track may bring to mind another completely unrelated track in totally different genre, its like my own personal radio station attuned directly to my mood, and this with SQ that competes with the best of best vinyl setups I've heard in over thirty years involvement with high end audio.
IME, there is no longer any reason to even start a physical media collection, just go straight to streaming, don't divide your expenditures over various sources, you'll get to great destination sooner than later with this focus.
