Also the quality of the vinyl and the method in which it is stamped determines whether there will be sporadic drop outs and noise (chunks, potholes, pits) in the groove walls. Some of this depends on the formulation of the vinyl compound, whether it contains recycled materials, etc. Even with a given formulation, there will be batch variation of the quality of the premelted pellets from the supplier. I have several pressings that, except for a few sections that sounds like tearing of the record, they are otherwise quiet and decent sounding.
How much does vinyl formulation have an influence on overall sound?
Sometimes i wonder if what we hear regardless if its a digital recording on vinyl or analog on vinyl, how much does the actual formulation have to do with overall sound quality. I am beginning to think a lot. Interested with your thoughts on this
