I'm with above! If I didn't have well over 3k albums I wouldn't bother with vinyl. I do like the art, physical stimulus and feelings of nostalgia playing records brings, but I'd not bother if I had lets say only 500 albums or so. I'd sell those off along with all vinyl equipment, streaming would be my sole reference source.
As for sound quality face offs, vinyl vs cd's or streaming. This has been back and forth battle for years. I can't determine some hard and fast rules in regard to cost differentials. I can say sound quality generally correlates to expenditures, gonna cost big time for both at the top end. My experience is optimizing streaming far more complex than vinyl optimization, far more variables what with networks, rendering schemes, music player software, linear power supplies, ethernet vs optical, local file implementation, must be forgetting something!
