Questions about the audeze lcd 2 classic / closed

I’m looking into getting my first audezes, and wanna know if they will be right for me

  1. Will my aune b1s be able to drive them at 110 db?

  2. Is the noise isolation on the audeze lcd 2 classics as good as the audioquest nighthawk or will I need to get the closed?

  3. What are the sound differences between the classic and the closed. I’m looking for something similar but better then audioquest nighthawks.
