"Old" vinyl, pressed before the digital era, when that vinyl was made from the analog master tape sounded great. I have several friends with 1000s of records bought in the 60s, 70s, kept in pristine condition. Most sound wonderful.
Current vinyl is a horse of a different colour. Almost all current vinyl you can buy (except perhaps audiophile pressings) has been made either from original recorded to digital masters or from digital copies of the original analog masters. Once the music has gone through one or 2 format conversions before being vinyl, it will have lost some of that analog magic.
So if a current purchase new LP sounds better on your turntable than your digital source, and they at some point were from the same digital master I can only come to one of 2 conclusions why:
#1 Your analog implementation (turntable, tonearm, cartridge, phono preamp) is better than your digital.
#2 Your analog front end alters the sound in some way that makes it a more pleasing for you. Nothing wrong with that. The purpose of this hobby is the pursuit of musical enjoyment.
I personally found very little difference on current pressings between my digital front end I described previously and my analog front end (VPI Prime, Benz Wood, Art Audio Phono preamp).
That's pretty much why I stopped buying vinyl.
So for those with huge old record collections, enjoy your treasures, but for those starting to build a record collection from scratch , well.... have fun I guess.
I no longer spend all that time physically going to stores to buy records although I do miss the thrill of finding a forgotten treasure in some dusty record bin in somewhere land.
