Hi everybody! I'm new here and i currently have my music discography in ALAC from 16bits CD, but that's not enought for me and i want to upgrade to 24bits but what's the best source? I read that vinyl is better but it have some noise on background, kinda of static. Can someone help me? PS: English is not my primary language, plase don't mind if i wrote something wrong. Thanks =)
