There are some serious heavyweights here in regard to turntables. From guys that have paid the cost and tried pretty much every table you can imagine, to people that are recording industry insiders that know what stuff is SUPPOSED to sound like based on mixing in recording studios.
I've learned bunches of stuff here from people that asked nothing from me beyond possibly an unspoken desire that I contribute what I can, when I can, in terms of knowledge or experience.
This kind of information used to get shared little bits at a time in person if you were lucky enough to know the right people.
Sometimes, you just need to start somewhere (get a turntable) and run with it.
