- @bobby1945, we recommend Townshend Podiums, they work with a large range of speakers and are available in different platform sizes and spring rates. Worth the investment imo. We use them with Cube Nenuphar’s. See David’s Cube Nenuphar thread for comments.
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.

Try combining NobSound, FOS or MD springs with Ingress cup and rollers to obtain greater freedom of movement in the radial and horizontal planes. You may have to use a transitional platform of a suitable material between the two different components in order to get stability. I have found slate to be good but there may be other materials that work in your system. |
Suggest reading Barry Diament research paper to start. Seismic isolation is essential and often overlooked. Suggest Ingress cup and rollers/slate platform/vertical isolation such as metal spring or inner tube. Townshend products are good as well. Stay away from points and rubber of any kind. Any material change will alter the sound but not always in a good way. |
Yes, Solid Tech gives more freedom of movement in the radial and horizontal planes than the NobSound on their own. You can combine NobSound with Ingress cup and ball supported on a suitable platform ( slate in my case but may be system dependant, worth experimenting with different materials) for better performance. Solid Tech, Townshend Pods, Geoff Kaits springs or kids tyre inner tube under inflated all good options to try under the platform. The Ingress cup and roller balls give you a very high degree of radial and horizontal freedom but couple in the vertical plane thus needing a spring of some kind for vertical isolation. I get extremely good results with this relatively inexpensive set up. If you can afford to spend more then take a look at Stacore Platforms. For a complete ready made solution at a reasonable cost it’s hard to beat the Townshend platforms particularly for turntables or where you use very stiff and/or heavy cables which can influence the performance of the Ingress cup and ball isolators. Note, that if using cup and ball isolators like Ingress, it is most important to set them up in a perfect equilateral triangle on plan for best results. In some cases you may need to support the cables with sky hooks for example in order that they don’t interfere with movement. |
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. |
@mitch2 thanks for posting Townshend link, I use them with Cube speakers and imo they improve clarity. I came across this which may be of interest as well https://youtu.be/5ihzvD3urc4 |
