Can you move the tonearm pivot point back to accommodate it? Other than that I have nothing further to add, sorry.

VPI tonearm length improvement
I conducted a quick search, prior to posting this inquiry and was left with minimal information.
I currently have the JMW 9” (2nd gen) on a VPI Scout. There is a listing on various audio sites with a 10” JMW arm for sale at $475.
The question is, would I see improvement in sound quality equal to the investment?
