The main reason to keep the vinyl is that although CD's have the potential for great sound, most are crippled by their producers to sound like complete crap. I can't listen to many of them, most are brick walled and even clipped. Vinyl through a moving coil cartridge and a vacuum tube preamp trounces the sound of most CD's. Not everything released on vinyl is on CD or other digital medium yet. If your vinyl sounds like rice krispies it's time to look for a better copy!I sold all my tube and vinyl gear back in 1999 and have never looked back. Beyond that, my 40 year collection of vinyl had been stored in the basement for over another 10 years before that. Unless you have some quad recordings from "back in the day" I can think of no other reason to hold onto the forever technically crippled medium. There's so little recordings that aren't available in Redbook and at the tips of your fingers from streamers to make the torture of listening to rice krispies unimaginable.
I do make digital copies of my vinyl (maybe 10% done), so no worries about wearing records out like I used to back in the day. People who aren't collectors will never understand why one would keep a vinyl collection if it's been digitised or replaced by CD's, or yuck, if you can just steam it off YouTube.
