An Epiphany

So, having had a bit too much to drink last week I stumbled up to bed expecting the wife to shut things down appropriately. She turned everything off except the turntable which she left running in the run out groove which I did not catch until the next day. I wondered how much damage this might actually do so I took another record and recorded it's run out groove with Pure Vinyl in 192/24 then played it overnight. In comparing the two I could not make out even a shred of difference. Now obviously a run out groove is not near as complex as music but it is a bit hard to play the same groove of music over and over again for 12 hours. What about 50k PSI turning vinyl into liquid? Why doesn't the stylus eat it's way to the other side? I played that same groove approximately 24,000 times and it sounded exactly the same.
Go figure.
