I use a standard Segue platform under my turntable which sits on my Symposium Foundation rack. I'm not sure that using wood under the Segue would be optimal in conjunction with the Symposium products as you may not realize the full potential of the coupling and dampening obtained with Symposium products used together. I understand that Symposium recommends the Segue ISO platform specifically for turntables and I've pondered whether that would be provide any notable performance different over the standard Segue I use.
Sorry that I don't have direct experience using maple under the Segue.
