Would an Isolation TT platform further improve my TT?

According to the last two posts it seems the the Luxman has a built in Isolation system w/the spring insulator feet. I wonder putting this TT on a block w/more isolators would diminish the sound. Any thoughts and opinions.

The problem for two stacked iso (spring) systems is they will interfere if the Fr resonant frequencies are close to each other. My Nirvana 2 stage isolation base has two stacked heavy mass-on-spring layers, where the Fr for each stage is predetermined to not be close enough to interfere. The lower layer of springs supports a much higher load than the top layer of springs. If two spring systems are arbitrarily stacked it will be like a car going down the road with two shock absorbers per wheel. It would not be smoother, it would be very bumpy.

I have always found that the more rigid the support, the tighter, more incisive and clearer the sound. Damping of the support by using wood or "absorbers" softens the sound. Marble and glass sounds etched while oak sounds warm etc. I'm old school and have to be convinced otherwise but spikes, cones and inertia allow the table to be as fixed as possible.

Which is why I built this.

Which all I know for sure is it was a big improvement over the floor.

The best isolation occurs when there is a great ease of motion. Therefore, ironically and perhaps counter-intuitively, a flimsy and flexible stand would sound better than a rigid one. A rigid frame actually transfers vibration more efficiently than a rickety frame.

Would you put performing musicians on active isolation platforms too ? Remember, seismic activity, traffic etc.
Only passive isolation, my friends, active will introduce subtractive colorations - often the worst kind of colorations.
