Springs under turntable

This is insane. Sound is getting better as they bed in OR as I acclimate to the new presentation. It's the delicacy thats amazing. Like going from an okay MM to a superb MC. It's also showing me that I was wrong about the limits of the Garrard/Decca as being a touch shy and rough and ready in the upper range. Nope. This is see-through detail. Best part is that the music isn't sharp and seering - it's warm and beautiful and very detailed.

@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.
