Springs under turntable


I picked up a set of springs for $35 on Amazon. I intended to use them under a preamp but one thing led to another and I tried them under the turntable. Now, this is no mean feat. It’s a Garrard 401 in a 60pound 50mm slate plinth. The spring device is interesting. It’s sold under the Nobsound brand and is made up of two 45mm wide solid billets of aluminum endcaps with recesses to fit up to seven small springs. It’s very well made. You can add or remove springs depending on the weight distribution. I had to do this with a level and it only took a few minutes. They look good. I did not fit them for floor isolation as I have concrete. I played a few tracks before fitting, and played the same tracks after fitting. Improvement in bass definition, speed, air, inner detail, more space around instruments, nicer timbre and color. Pleasant surprise for little money.

Folks,
I have just ordered three Feet of silence from Solid-Tech for my turntable on their website. Solid tech has already shipped it from Sweden and I am expecting it to be in the US within a week. I will let you know its performance once I have it in my music room.
Thanks.

@millercarbon,

On your diy springy thingys are they positioned between the bottom of Moab's and the mdf plates?

You are not using the provided spikes into the mdf and the diy springy thingys on the bottom of the mdf plates?

Thanks
Moabs are on BDR Cones, on MDF Spring Thing. Springs are on BDR Round Things so they can slide over the carpet real nice. 
@indranilsen The FOS heavy duty only support 3-6kg per foot. My turntable is at least 40kg.
