Been banging on about hardwood supports forever here, met with complete silence, sometimes you need to give something a go rather than ignore the obvious because your entrenched in hifi magazine speak from the 80's, i too believed it & played along for far too long.
Your description is almost spot on with a description i gave a few months back, much derision followed, obviously, i would stick with the height thing, much safer here, don't dare claim the wood support has improved matters "musically", forbidden word
