Well, there is vinyl and then there is vinyl. Always has been. But of all my recent buys of both old and new music, some sound like a bumpy noisy thing with no range and can be even off center (but clear or colored WOOO!!!) and the others - usually the solid colored vinyl blow my socks off. But still, they are almost all better than CDs, at least for me on my system.
But my recent purchase of the Pachinko soundtrack (clear vinyl - how do they do that?) is so bad that it's going back.
So yes, some sound like they were cut from redbook CD bit rates but others are amazing. I see no trend.
