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.

indranil,
another way you could try is to get the number of springs you have (hoping four?) under a heavy shelf, larger than the base of the TT you are using. Get the shelf completely horizontal, buy starting from the furthest edges of the shelf that will accommodate the leveling, moving the springs to suit under the shelf, creating the broadest sprung base. Now find where the TT with a record in it will sit on your shelf where that position will make the entire shelf and TT horizontal. Hopefully the center of gravity off the TT will align with the centre of gravity of the shelf in a vertical alignment.

millercarbon - now you can see why Townshend calls it seismic isolation!
I am glad you were willing to try it, to discover it for yourself.

And the springs on your wooden floors might be about the same as suspending the cables, have you shored up, or propped up under your floor where the springs are yet? Because if you have not, I wager money on it, there's more in store for you yet.

A room on a suspended floor versus a concrete floor can only throw up so many issues around vibration and resonance, I can't imagine how I'd go about trying to fix all of them! Starting from a concrete room allows me get past all of that. Consequently, my system is very responsive to small changes and tweaks.

@noromance- That is very true for a concrete floor...While it doesn't absorb all the seismic vibration issues but it allows these tools to work optimally relatively easily. You are one of the lucky folks to have the advantage of a concrete floor and can focus more on the music....
Thanks.

Actually all concrete does is alter, not eliminate, vibration. 

I'll get around to shoring up under things. Its on the list. But its a long list. Still need to finish the Spring Thing, add springs under the rest of the subs, and amps, and suspend a few more things.  

For now my system sounds so freaking insanely good its hard to do anything but just listen and try not to gape and drool.
More to discover
