You're welcome. And good to know. But I was talking about the spring setup mitch2 is using on his system page.
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. |
The only thing a concrete floor does not isolate you from is an earthquake. None of our systems have enough power to move something as heavy and stiff as a concrete floor not to mention it is sitting on compacted stone dust. Millercarbon, glue an accelerometer to you garage floor and record its output while you start up your car, rev the engine and drive in and out. Please tell us what you get! What I see here is a lot of wishful thinking without any science to back it up. |
Mijo To be fair we could be talking about two different types of concrete floor here. You have the solid concrete floor like mine that is sitting on bedrock stones, dirt, whatever etc. Then you have the concrete floor that is a platform so to speak and is suspended. See link just as a FYI. https://thermohouse.co.uk/blog/suspended-floors/ You will get two different results from the two different types of concrete floor. |
Actually all concrete does is alter, not eliminate, vibration.First up, my concrete is a fully sunken basement. Dead as a mountain. It’s not a suspended concrete/rebar floor where I can imagine some vibrations. However, there is NO comparison with my basement and a suspended wooden floor and more importantly, wood/sheetrock walls. |
