Springs under turntable

Same here. Good one. Thanks!

Noromance, bad design for anything. If you could get them down to the right resonance frequency they would wobble all over the place. People were also discussing the use of springs under subwoofers and I expressed my opinion that it is not a good thing to do.

As far as Bass is concerned, everyone should have a pair of good head phones. Forget about the image but focus on the sound and detail. This is the bass you should hear out of your system ideally. Using a record with an acoustic bass solo to compare is ideal. If you like pushing the lower frequencies louder as a matter of taste well, that is up to you but you will sacrifice some detail. 

Indranilsen, You have to level the turntable with a record on the platter and yes it always matters. Perhaps not as much with a pivoted arm as with a tangential tracker but still. You may also want to adjust the feet so they all bounce together if you can. Lock the tonearm in it's rest. Push the turntable down stretching all the springs to their limit and let go. The springs that bounce fastest are farthest away from the center of mass so move them a little closer to the center of the turntable. Try to adjust them so that they all bounce together at the same rate. The games we children play. 

I think that using prings under a turntable must be very delicate indeed.... And it is not the same at all than under speakers....

These nobsound MUST be adjusted near 1 % of optimal compression....For a turntable it is way much delicate and refine adjusment necessary even about the structural properties of springs themselves more than for speakers....

That explain some difficulties with springs under turntable....

Under my speakers they are fantastic at the express condition to be very adjusted.....You cannot do that in one or 2 trying....

Beware of much clarity in the sound....The first clue that all is OK come from a better timbre accuracy not clarity only.... I made this error the first listening, i concluded too early that all was ok.... I corrected the load a couple of times and when the tonal accuracy was there all was positive on all counts.... No trade-off....

@toetapaudio, @mijostyn, @mahgister- Thanks for your feedback. I will have to adjust the turntable feet height to make it 100% leveled. With springs underneath it sounds like another time-consuming adjustment work that I have to add to the mix....
I have worked with inner tubes, have the Ingress roller bearings to address the seismic vibration concern but what I have experienced is that it always comes down to this finer calibration/load adjustment factor which is very manual and very time consuming. You can easily spend hours without getting the desired results... I wish there are tools available in the market to complete this load adjustment step quickly and accurately. Yes I am familiar with Stacore platforms, another super expensive isolation solution but I doubt it comes with any load adjustment/calibration tool without which the total investment becomes worthless. Interestingly very few manufacturers talk about it let alone building it in their products.
I would love to get all my components isolated from the seismic vibration and I am ready to pay for a commercial solution but just not ready to make a huge investment yet spend hours in setting it up to get the maximum isolation.
What are your thoughts on this point?
Thanks.

My experience is the adjustment is less difficult with some choices of music you know very well...

Choose violins solo and in mass.... For higher frequencies...

Choose brass ensemble with tuba, trombone, trumpet and horn... for the bass level...

for example : Empire Brass playing Gabrielli

Human voice solo is useful indeed .....

Always adjust in relation to timbre accuracy never in relation to clarity only  or bass....
