Thoughts On Turntable Clamps And Weights

@pindac My wall shelf will be mounted to a plaster on brick wall. I will drill into the brick an fasten the appropriate anchors, readily available form the local hardware store. I have done this before. As an extra measure I also glue the anchors into the brick. I could sit on that shelf.

Get the app and check out how your situation is doing now. I think the app is free. When placed on the platter should be able to jump and bang around without anything registering on the platter. Wall shelfs may help with severe problems like foot fall issues but they are poor isolation otherwise. You can prove that to yourself. Get the app. it will tell you everything.

@mijostyn What app do you use (I am on iPhone)

I picked something off the app store, and vibration seems negligible to be. During normal play it says vibrations can only be detected by instruments, and if I bang on the isolation platform with the phone on the platter it says very slight vibrations felt only by some people. 

But like I said, I listen to large-scale orchestral music all the time, with large speakers and subs in a smallish room, and I can pick out plenty of inner detail.

At some point I will borrow a HRS platform from my dealer to see if it makes a difference, but for now I don't have a problem to solve, as far as I'm concerned.

@dwette ,

That app is referring to earthquakes! The one I use is labeled Seismometer. I also use an iPhone. It looks like a real seismometer. There is a needle that paints squiggles on a graph when you disturb it. If you put it down on any surface and tap you will see a sgiggle. I have it open right now and it is registering me typing. if you go to the app store and type in seismometer, "Vibration meter, seismometer" comes up. "measure all vibrations." that is the one.  

@mijostyn who's the app publisher? There's more than one fitting your description.

The one I got comes up as "Vibration Meter, seismograph": "Measure all vibrations" by ExaMobile S.A.
