Post Subject: It does need EQPosted by Paul S on: 4/24/2021
Robin, your point is well taken, but I don't think they are trying to circumvent the laws of physics here. I did not read it yet, but Alexandre did provide a link that gets one in the vicinity of an explanation:

Clearly, this EQ system is based on the RIAA curve embedded in the LP grooves, and just as clearly it might be adapted to other recording curves.
Not saying I understand how it operates so precisely, to begin with, but I have heard that optical readers are integral parts of high speed manufacturing processes that are just as amazing, in use all day, every day, around the world.
Best regards,
