Springs under turntable

Right, that's the problem with concrete and stone, they ring. They are not inherently highly damped materials. What sounds great with a certain system at a certain level may not always sound so great as it gets better. With mine the problems with concrete and stone only started to sound like problems within the last couple of years. Before that it was like they were providing a solid foundation of impact and slam for bass and dynamics for midrange and treble. Then as things got better it gradually became more and more apparent the "contribution" they make is ringing. They add a certain hardness and glare. No getting around it. 

Concrete (and stone) being massive and stiff makes for a great platform or base on which to build. But they are not that great in and of themselves. Vibrations travel faster through hard high density materials like concrete than through soft low density materials like wood. That's just basic physics. So the fact concrete moves less at low frequencies really only makes the high transmission rate of higher frequencies all the more obvious. 

It just might not be obvious now. But it will be, if you go far enough. Then you will be ready for springs. They are so cheap and easy to do though its hard to see why anyone would want to wait.

Hi @indranilsen, our set up atm is Ingress cup and rollers set up in a equilateral triangle on plan, balls touching the equipment directly, bases sitting on 30mm thick black slate which are square on plan, with springs supporting the slate platforms. The springs sit on one of our toetapaudio designed maple Audio furniture which is supported on Ingress speaker type double cup and rollers in each corner, four sets in total.

One could try fixing Ingress rollers directly to top of NobSound or perhaps Feet of Silence springs (use industrial double sided perhaps for a quick test and then perhaps use Epoxy at a later stage. Mechanical fixings would also be possible). You need both rollers and springs imo for best results (see Barry Diament).I may experiment with NobSound and FOS in this way but Ingress are also developing a version which incorporates a spring which I’m hoping to test the prototypes soon. I also have some designs of my own which I might get made.

All this is really worth while. Makes a huge difference. Don’t even think of upgrading until you are on top of seismic isolation imo.

There is another type of isolation which I’m looking into which might be interesting. I’ll let you know.

I am waiting for someone to advocate some sort of springs for one's listening seat.  After all, if all the equipment is bouncing around, shouldn't the listener be moving in tune?
Indranilson, I would not be too anal about perfect level for your turntable, although it should be very close to level if not perfectly so.  But what is more important, if you are going to spring load it, is that the spring action moves the table in the vertical direction with perfect symmetry or near to it.  You don't want an external disturbance to cause one end or corner of the table to move more than any other.  In the extreme case, this could provoke a mechanical oscillation. Could also cause problems with tracking the LP.

@lewm - I won't advocate for springs under the seat, with the speakers and electronics isolated correctly, there's absolutely no need. However nice padding to make it comfortable for hours of listening pleasure, ah yeah, I fully advocate for that!

Enjoy the tunes :-)

I don't use a sprung turntable, but in the days I had a Linn....the springs should be wound in different directions to cancel each other's bounce.
