I've noticed that the louder sounds, like loud vocals, will sound grainy and distorted. Just an overall lack in clarity across the whole spectrum. I've been thrown into an OCD fit over this, but who knows...maybe a lot of my albums just have groove damage. That would mean that all my obsessing over this was for nothing, because you obviously can't do anything about that except buy new records. People have suggested buying the MintLP protractor, but I don't see how the provided alignment chart can be THAT flawed to the point where it doesn't even remotely do a good job at alignment.
The other problem is that the Virtuoso is a much more detailed and revealing cart than the Goldring 1012 I was previously using; these albums may have always been damaged, but now it is just easier to hear.
