Old vs. new
I have a simple(maybe?) question for you guys, I have some new versions of albums that I’ve replaced from older vintage records that I’ve had thinking they would sound better than my older ones, but they don’t, since vinyl has made a comeback , we’re the older versions engineered and mixed for vinyl and now the new recordings not mixed to favor vinyls characteristics?
