Anti vibration stand

So.. I have never been able to set up a turntable in the living room because there is just too much movement in the floor when walking through the room. My set up is all in the basement anyway, but I would still like to have a set up on the main floor too.

I tried setting a turntable up on a mini-trampoline on the shaky floor and sure enough - no amount of stomping could get that thing to skip. Not a practical solution by any means, but there may be a seed of an idea in there somewhere...

or you can put a micro mini-trampoline under each foot of the table. IE ash trays and a but load of rubber bands
 
How many times nowadays, do you see something for the first time? I just love the idea, if I only had a trampoline to try it out...
 
If your turntable feet have a concave bottom the use of Double Yellow Dot Squash balls works very well. I use them on my home built table. They are available in different absorption rates depending on the weight of the table so it is basically adjustable by using different balls.

Problem with this idea is rotational energy will be stored from the turntable motor so the turntable will keep wobbling. Isolation is good, but trampoline is not.

I had a similar issue so I installed a dedicated TT shelf on the wall near the system. No issues after that. No quite as ingenious as the trampoline though.

This works for floor vibrations? The article states it is effective for "airborne vibrations".

Truthfully - the trampoline was in the living room because my daughter wanted to use it while watching Netflix... :rflmao:

I played 2 records on it and put it all away. A wall shelf is not an option in my living room at the present time and neither is a trampoline!

Yeah - like this:

I am sure that even though the TT is pretty balanced, there will be a micro wobble there. I still think there is an ingenious solution somewhere down this road. With the correct density of springs vs table weight a happy medium could be achieved. I am not the one to pursue it though - was just having some fun.

Yes, at least in my case. I´ve got suspended wooden floor that would bounce (not that much as the wood quite inelastic). So, I built the
sand platform mainly for the unwanted effects arising from the wooden floor, in particular when somebody is walking.
 
I use to have problems like this on my wood floor. I now have a better table, cartridge, and phono stage and I can literally jump on the floor right by my stand. Nothing crazy expensive either just quality stuff with a proper cartridge alignment. I also use a 1000 watt subwoofer in my setup with zero feedback issues.

Current setup Sony ps-x70, Ortofon 2m bronze and Yamaha C-85 pre
 
Typical solution if you can't use a wall shelf are combinations of high mass and a way to absorb some movement. Some solutions have been squash balls, or half-tennis balls or similar either under one layer or in between two layers of something heavy - concrete patio paver(s) for example (which is inexpensive but not pretty). For pretty, a slab of marble or similar stone will work. Wood butcher block may work. Try the paver route as a cheap experiment and if that works without breaking the furniture, you can move to using something prettier.
