For the past year I have been using an SME 20/3 TT with the Series V arm and a Lyra Skala cartridge.
Lately I've noticed damage to 3 or 4 new LPs unlike anything seen before, very localized groove damage from <a half inch to about 2 inches, the rest of the disk being pristine. The groove looks as if scored by a tiny chisel. The sound is a brief, "zip" noise lasting up to 4 or 5 passes, after which the record plays normally.
My first thought was cartridge trouble, but the Skala tracks perfectly and silently, and the damage is localized to one spot on the disk. Therefore I don't blame the cartridge but don't want to risk further harm to my record collection either.
I suspect that the groove damage on these new LPs might be a flaw from the manufacturing process but seek some advice.
