My digital streaming leg of my system sounds as good and sometimes better than my very good vinyl leg. I don’t think recording my vinyl would improve the sound.
Since I think it is pretty natural once streaming’s sound quality is equal to or better than that of your vinyl collection, most folks focus changes from the few thousand recording you have heard many times to the millions you have not. So, the question is tricky.
Personally, I do not waste my valuable time copying music when I have millions of albums at my finger tips.
