It doesn't work that way. I mean if you stick an AT440MLA on either tonearm, you are not going to get midbass bloom.
As for the collar, yes the stock one does not cause severe problems and is fine for most people. However, if you try to print out and use an arc protractor, you cannot trace the arc well because the arm pillar is not vertical. May or may not be audible to you but what I say can be easily verified.
