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.

... But out of level a tonearm will add additional skating forces ...
That’s true.
... in an ideal world all parts of the turntable should operate in exactly the same plane.
Yes, or at least in parallel planes for the turntable, plinth, and arm.
It is just a good measure to put the bubble next to the part that matters the most ...
If you’re using a typical little bubble level to set up your turntable, it’s no wonder that you have some of the playback problems you report. You’ll get more precise results with something like this.
... Unless you are using an arm that is dead straight raising and lowering the arm will change the azimuth ...
Correct. But there’s no reason to accept a turntable setup where those critical component parts - turntable, plinth, armboard/pickup arm - are not in proper alignment. If they cannot be properly aligned, then one or more of the parts are defective. Or poor quality. You've previously said that your stylus tilts towards the spindle when the arm is raised, but I wouldn't accept that from my turntable setup.

... the devise that has to be level to prevent skating forces is the tonearm. So the best place to put your bubble level is on the tonearm board or plinth right at the base of the tonearm. If the platter is a tiny bit off it won’t matter.
Even a level pivoted pickup arm will generate skating force provided the arm has overhang, which almost all do.

The armboard, platter and plinth should all be located on absolutely parallel planes and if they’re not, there will be an issue. In mijostyn’s case, he’s mentioned several times that his pickup arm azimuth changes when VTA changes. That can be explained by a misalignment between arm/platter/plinth.

Cleeds, yes I read tea leaves but most importantly systems like mine are obviously very rare at this point ...
I'm not sure your system is that rare - I've seen lots of systems like yours that included the flapping woofers that you think is inherent to LP playback. But if you're happy with your system, that's all that counts.

Lewm, you and none of those other people obviously have not heard a system like this.
Impressive. Do you also read tea leaves, tarot cards and perform remote viewing?
... A good suspended table should be immune to everything up to an elephant stepping on it ...
I'm inclined to mostly agree. And yet, in another thread, you claimed this:
If I delete the subsonic filter from the program it ia mass pandemonium. It looks like the drivers want to jump right out of the cabinet. It is just inherent in vinyl if you have a good system capable of reproducing deep bass.
As I've mentioned, and as many have demonstrated, such a problem is not at all inherent in LP playback.

Uberwaltz, you REALLY need a Schroder CB on your Avid ... It is the most perfectly designed pivoted tonearm in existence
It is? Do you own one? Have your heard one? Tell us more.
