homemade turntable vibration isolation platform


Out of a couple years of frustration, I irrationally tried to create my own turntable suspended platform to cure two problems. First, footfall would often jar the stylus enough to skip and my music seemed muddy/blurry. The floor bounced enough to make us have to tip toe through the living room. It was getting where I would hate to even play a record. I went searching for tweeks. Ideas abound. Ropes from ceiling, etc. But I live in a yurt. Everything moves, including ceiling beams. Floor works like trampoline (almost). Out of complete desperation, I drilled holes in the top of my component cabinet (double 3/4" plywood) and suspended my turntable on another piece of plywood by bungees from four posts. I got lucky!! It worked fantastically. One could almost jump up and down in the room (my wife tried). AND, a solid bass appeared, soundstage grew a third larger, the clarity was enhanced exponentially. Pure luck I cured my years of frustration and got an indescribable upgrade sound quality besides. After 6 tries I've recreated a free standing unit that works as well. Just had to share.....

Right. And it needs to be tuned according to both the frequency and amplitude of the vibration you’re trying to filter out, as well as the mass and fundamental resonance of the device you’re using.

>>>>Huh? No it doesn’t.
Bungee cords are like any other type of spring, they can be used to isolate any and all components. The trick is to match the spring rate of the bungee cords with the mass of the component, you know, like any other mass on spring. Ideally you want to obtain a smooth very low frequency up and down motion when pushing on the component.
