If you floor is on concrete and your equipment rack is sturdy just use the maple. Wood that thick is very dead and maple is very heavy, perfect.

Are you kidding me? We have an earthquake every 5 minutes? You might as well worry about your grandmother driving through your listening room in a drag line.
