The positive changes one can make to vinyl are really incremental. Your talking, primarily, about a mechanical product...not a plug in and play electrical one. Tinkering goes a long way to getting it to sound good...most folks these days don't take the time to do it as they are drawn to other things (cellphone, work, family, computer, etc)
But, for those that tinker relentlessly, you get the best playback of those available...despite it being a 100 year old technology now.
Once you dial in several of them right and your rig is respectable you get that moment where you realize all your efforts are getting similarly priced digital gear was all for naught.
Ruthlessly clean records are a great advance in your listening pleasure. The benefit in tracking, lower noise and cleaner/clearer treble performance (where you start to realize how bland CD/Redbook is) is much, much better.
