phono stage break in?

If my stereo is playing I have to listen. I don't care how it sounds. A full orchestra usually has full spectrum of music. Use real music for breakin.
Every component(cables are not a component) I ever had not only requires breakin but except for speakers require warm up. Out of the box they are simply unlistenable.
The more expensive the more breakin time. I have also come to the suspicion that the reason so many great products sound awful at the store is inadequate breakin. Cheap products are playing all the time. Expensive products are turned on only for "special customers." Electrostatic speakers need to have thier transformers breakin and warm up.

"Do we hear various components break in? Absolutely. Some more than others, as has been noted. Cartridges, speakers, tubes, capacitors, interconnects and cables (even if cables aren't "components"!)."
We already had the do cables breakin debate on another thread. Judge for yourself.
