Is There Any Advantage To Move To A Herron Audio 2-2A From A VTPH MC Plus ?

If Using An MC Cartridge Only ??
Researching to buy the 2A everyone said it was a worthy upgrade from the 2. Coming from the MC Plus should be dramatically better. 

Read the review of my system. Everything matters but the Herron contributes big time.
What not call Keith and ask him?
