I am finishing up benchwork tomorrow, so the next step will be to start on the elevated line. I need to know how necessary is it to have homasote if I am using cork roadbed. I would say I have seen more than a few layouts with cork or foam roadbed only, with no homasote. So are both necessary? If I can I want to use just the cork.
I would really like some feedback from some that have used both methods. Is there really a large sound difference? I am using Atlas track.
Thanks in advance for your replies.
