Granite base, stainless steel platter, etc. total weight of 100kg. The super-heavy body suppresses unwanted vibrations. The platter and tonearm are air-floating, so the air film also absorbs unwanted vibrations. The 27kg platter is supported only by the pressure of the air (only a few hundred grams). Normally, with a single point of support, you’ll hear a dinging sound when you hit the platter, but by damping it with an air film, you’ll get a knotty sound.
