What is under your TT, cheap islolation?

I am looking for a way to isolate my turntable without using a shelf bolted to the wall. I am trying to save money while I re-configure the room. For now my turntable is on top of my stand but you have to tip toe around the room. I am wondering if a big rock iso platform (or DYI version) or some iso nodes under a butcher block would help with the bouncing turntable? I have two tables I am testing at the moment, one is a Thorens TD-160 & the other is a VPI HW19 MKII, both of them suspended. The floors are pretty sturdy, it is a dedicated room over my garage with serious supports built in to the floor.

Hi fishwater,

One extra thing you might try. This is something that was recommended to me since I also use sandboxes (see my system pictures). That is to make a few pieces of MDF or some of the poplar into strips, maybe 1 inch or 1 1/2 inch in width and glue them on edge to the bottom of the top shelf. This way they protrude down into the sand and act like sinks. Picture it like an upside-down heat sink. I'm in the middle of a couple of other projects so I haven't gotten around to trying it yet. It does make sense though.

Best of luck,

Dan

I was afraid of that. The problem is the sandbox is great for vibrations but, obviously, it is bouncing with the floor as well. As others have mentioned the real solution is to completely decouple from the movement of the floor. You could try moving to a wall or corner that has a load bearing structure beneath it in hope that the floor bounce won't be as severe in such a location. Otherwise, it's either the wall shelf or hanging it.

BTW your sandbox could still be of benefit on a shelf.

Don't give up!
