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.

@millercarbon Can't wait to hear what you think. 
Percussion is spectacular. Julie London on mono from 1966 can't be mono!!
One small downside. Poor recordings are laid out in their inadequacies.

"What is going on?"

You’re decoupling from floor bourne, mechanical, and acoustical vibrations.

Hello,I have been experimenting with springs for sometime and I have the Nobsound springs/disks as well. What is important here, in my opinion, is to get the correct set of springs that for a given load bring the resonant frequency of the platform with the load to below 5 hz. Without that you are likely not going to get much benefit although they might sound better than any tightly coupled solution.
Also you have to pay attention to asymmetrical load distribution of the component which would require different set of springs under the platform. I prefer putting the springs underneath the platform instead of directly coupling to the component because that allows you to design isolation in the horizontal/rotational directions on the platform like roller bearings.
The good news is that none of these challenges are insurmountable if you have time to experiment. In the end I agree with you all that isolating your audio/video components and addressing the seismic vibration challenge is the way to go...Thanks.

@indranilsen Thank you. It's sounding so good now that I'm noy going to change it! However, I'm going to try them under another the platform of turntable when I get more Nobsound sets.

@noromance- Glad to hear the improvements that you are getting out of the springs. Does it provide isolation against footfalls/subsonic frequency band?
Thanks
