@joenies,
I am glad that you experimented and tested springs under your non suspended turntable because now I don’t have to. I also have a heavy mass turntable (Transrotor Apollon 80MM TMD, roughly 130 pounds with three external motors) resting on a nearly 300 pound Clearaudio MontBlanc turntable stand (columns filled with concrete), on a concrete basement floor with stranded bamboo.
I would like to know what issues you are trying to resolve or if this was a matter of experimentation? I can knock on the turntable stand and I don’t have any resonant sound getting picked up on the tonearm (who does that when listening to music anyway?), and I am also not getting feedback from excessive loudness from music and bass. It’s not happening, dead silent, so I don’t even think about adding suspension or suspending the turntable because I am completely satisfied with the performance based on the aggregate of the design parameters of the entire system. That is what is key here, synergy of the entire turntable system.
Herr Reike from Transrotor has designed some really nice turntables over the years and acoustic feedback elimination is part of that recipe going into the design and build of many Transrotor turntables. Here is a nice video explaining the build details of Transrotor. https://www.youtube.com/watch?v=L38cZ0Bj-Ys
That is why I never bothered to concern myself with the idea of adding a suspension system under my turntable which is built under the principal of being unsuspended.
A few of my Deutsche audio friends scoff at the idea of adding complexity to an already rigid system combined with mass loaded racks etc, which help to ameliorate many floor and vibration issues. They rationalize that the precision of the design and noise reduction of the combined materials make for a very quiet platform to start with. I guess at the end of the day, tomato or tomatoe, whichever solution works best for each individuals system is best for them, but not best for all.
Thanks for the feedback on your attempt of using a suspension system under your mass loaded turntable. It is good for some, not so for others.
