Warm up time for record playing


It seems that my records don’t realize their full sonic potential until about 45 minutes of playing. Even if the rest of the system is already warmed up.
Does anyone have an explanation for this?

If it was just your hearing changing than digital sources would take just as long but they take 20 minutes compared to nearly an hour for the turntable. 
Nah! But, I did like the first version of your post better, Slaw. That’s one; thirteen left in the bank. Does thirteen buy me a piece of plastic?  (You just had to go there, eh?)
