Typically 2" - 4". Some application may work better with thinner platforms. For turntables and CD players for me, thicker has worked better.
By better I mean less exaggerated and more "natural" sounding highs, smoother but more detailed midrange, cleaner and better articulated bass. The whole presentation just sounds more coherent and better put together.
