Easy solution. Just listen. Get used to the sound with the felt. In a few days remove it to compare. Doing an A/B comparison right away doesn’t work as well.
Horrible solution. Where would this website be if people tried and listened instead of wildly guessing and pontificating? Don't listen to this wild man. Keep posting and asking until you find the one saying what you already decided to do anyway, and then do that, but under no circumstances actually compare by listening. Once you start down that road no telling where it leads.
