Live Vibe does not use stainless steel but instead a low speed steel chosen for its sound quality. I know I was part of the listening panel. We had several of the same platforms cut from several grades of steel. The hardest one was the worst as the instruments and voices traveled up the wall towards the ceiling junction. Like sitting in the front row of a IMax theater wrong and uncomfortable. Aluminum and tungsten portray a similar perspective and sometimes painful. The platforms were listened to in several different systems and rooms all of us came to the same conclusion. TomD
