A good friend who is into restoring analog tape recorders such as Ampex has a clever and true watch phrase:
“before everything else, make sure the tape runs and is aligned perfectly.” all else follows; without that nothing matters. I am paraphrasing…

Analogy for this is perfect playback from the groove - the recording chain after that is trivial these days.

That said, I will listen!

The overwhelming weak links in the chain will be in the analog domain, namely, the inherent limitations of the analog vinyl disc itself, its condition, how well it is cleaned and how well it is played.  The other weak link is the skill of the person doing the work. A sufficiently competent person knows his tools, how to achieve the best results with them and just gets on with the job.
