Did you mention you have a phonostage? I didn’t see any mention of one. So if you’re using a phonostage that’s internally contained within the turntable, then that could easily be why your digital setup sounds better. I find that most people, listening to popular music as they do, will think digital surpasses vinyl. But listen to a recording of a flute (an instrument i play), or any other well-recorded acoustic instrument and you will hear the difference between the two more easily, and I wouldn’t be surprised if the vinyl sound was closer to how a real flute sounds. Of course, that begs the question of how many listeners KNOW what acoustic instruments sound like. I get the impression that’s not the case. I mean, that the majority of people’s music is acoustic. Even if that, the ’80s produced the worst vinyl - and sound - of the 20th century. Vinyl was so thin you could flex it easily. NOT the case with an lp made in 1960.
So, If you are listening to classical, I can imagine the vinyl sounding better. But if you listen to pop, rock and the rest of the musical genres, then I could see digital sounding better, since so much music is overly compressed and manipulated.
What do you listen to?
