Even in the recording studio back in the days of vinyl pressings all ran on studio grade magnetic tape with a higher dynamic range (not by much, albeit), but the sound that the artist was going for was typically hindered by analog recording media in a way that isn't true today.
It's not really a case of them "producing different frequencies when read." It's that CDs are capable of recording and reproducing a broader range of frequencies than vinyl.
Which is a shame for me since I have a entry-level-audiophile setup and just stream and have little desire in getting into vinyl.
You can read them without damaging them slightly. You can't make a perfect copy, so when the vinyl detoriates, you will not be able to "make a fresh copy".
CDs can be copied perfectly and can be moved to superior tech, e.g. SSD. You can continue copying a digital version for the next 1000 years without any loss.
