I listen to all of my music on hand (vinyl collection). There are definitely some better sounding records than others. There are incredible sounding records, too. And there are a few that are just terrible sounding. I still listen to all of it. However, those lesser sounding records just sound better to my ears when the volume is adjusted accordingly. That is to say, for lesser quality recordings I listen with the volume lower than I do for the high-quality recordings. It seems to work better for my ears and allows me to have a more enjoyable listening session.
My system is quite good and is revealing, and my room is fairly well treated. I get from the records what they have to offer. Again, I adjust the volume accordingly and enjoy my record collection in its entirety.
