Your premise (the thread's title) is faulty as is your logic about using a laser. A rock at the end of a stick is extremely effective at tracing the grooves on a semi-solid slab of processed decomposed organic matter.
No cartridge is good enough.
It appears that even the very best can't extract everything from the groove. Yes, along with table/arm.
Is there any way, theoretically speaking, to take cartridge design and execution to a much higher level?
What about laser instead of cartridge/arm? I know there was/is one company that tried. It didn't sound better and required cleaning records before each play. But laser could be improved. This approach didn't take off, it would seem.
