Springs under turntable

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

No idea, Indra. Concrete floors and walls in basement. But I am literally hearing stuff I didn't know was there. 

@noromance- A few tips on using the Nobsound springs. This unit is a clone of a much expensive item called Iso Black manufactured by a Swedish company Solid Tech. Here is the URL: https://www.solid-tech.net/isoblack/. They used to have a manual which documented the most effective layout of the springs when you are not using all 7 springs. You can download a copy of that manual from the Audio Advisor website who is one of the Solid Tech dealers in the US. Here is the link:

Follow these layouts for the maximum performance.

Also be careful about putting the black rubber mat on top/bottom of the aluminum discs. In my case they added too much damping effect to the sound. You might want to try the discs w/o the black mat first and use it only if there is any audible ringing.
Hope that helps.
Thanks.
