Thoughts On Turntable Clamps And Weights

@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.

Go to yellowagents.com/seismometer

@mijostyn OK. I got that one, for a couple bucks.

If I put my iPhone on the platter and bang on the isolation platform I get tiny little blips (like small bubbles). If I bang on the rack the isolation platform sits on the tiny blips are even tinier. If I walk around there is is nothing.

As an experiment I also wedged the phone between the arm board, and the base of the tonearm, while playing the MMJ45 of Art Blakey and Jazz Messengers Mosaic. That should load the room with enough bass and dynamics. Without doing anything else the measurement is a solid straight line while the record plays: no blips at all. While I'm playing that I bang on the iosaltion platform and get tiny blips, and can kind of hear it in the bass. And banging on the rack the isolation platform sits on results in even tinier blips. No mistracking in any case.

I should try Weather Report Sweetnighter and turn it way up to see what happens.

Bottom line though is that while I'm playing a record it's not recording even the slightest vibrations that I can tell.
