It was an obvious question to answer: hard needle vibrating in a softer surface jagged groove. I was trying the gauge how long a record would last before the sonic properties were effected. Over a period of time, hearing the same music on vinyl would surely effect the sound. Would a user adjust their system to compensate, thus compromising other areas of their system.
It was just a thought bubble I had as I resume my vinyl journey (from the 1960's). is there anything that can be done to slow the process... besides not playing them as much. I have albums where I may play some favourites more than the whole side. Wear in this case would not be even.
