Two things you can't cheat with vinyl play.
1) Physics and 2) the Record Pressing Plants.
PHYSICS (the obvious one)
Raise VTA ....you lower VTF and alter other set up parameters.
Lower VTA....you raise VTF and alter other setup parameters.
RECORD PROCESSING PLANTS. (not so obvious)
There were / are no standards for the vertical angles the records are cut at (the included angle).
American plants angles are different from European plants.
Each time the cutting stylus is replaced (every 10 hours?) the new one goes in a little different than before. 8^0

What to do ?
********************
If with one average setting your vinyl rig does not allow you to hear these differences, or it does not bother you too much.... consider yourself BLESSED ...enjoy your records.
If however you hear differences even with same thickness records (different included angles) ....and...maybe..... suffer from a little Audiophilia Nervosa...... there are at least four things you can do from my personal experiences over the years.
1) make the necessary adjustments after VTA changes.
2) acquire a preamp with adjustable on the fly "Gain". Lower gain for bright records and vice versa.
3) acquire an amp that allows for on the fly gain changes.
4) acquire a tonearm that was designed with VTA changes in mind and allows you to make these VTA changes, with ease, and not affect any other setup prarameters. FWIW - One tonearm only - exists - that I am aware of that has this capability. ET 2.0, and ET 2.5. They are protected by patent.
If there is another tonearm let me know.
Cheers
Enjoy your records.
