Crazy ass Audio tweaking

[bobhol]

Oh please kind sir (richard51) can we have some pictures of your stoning process.

 

[garbulky]

Hehe @richard51 I have been in contact with ya for sometime over at headfi. I'm surprised you bought this up here. I was almost run out of town for my preference not to use USB! The reaction to your rocks seems positively charming!

Is the purpose to try to find a scientific basis for rocks "cleaning" the power grid, or just to throw it out as a subjective impression, and leave it at that? If the latter, then this thread is done. If the former, the best thing to do (for this forum) would be to measure with and without rocks to see if there is any performance difference. It is always possible the rocks add some shielding or whatever though it seems unlikely there would be any significant difference. Or maybe rocks and substrate (I assume something is holding them in place) provide shielding. Or this is just another hoax meant to annoy people.

I think everyone in the US is buying stones since we won the gold medal in curling yesterday.

Sal, you need to stop reminding me of this! My only comfort is that our Swedish ladies won the gold ...

I believe granite blocks are pretty good decouplers and speakers stands.

But I wonder; is there a rule of thumb as to how heavy the (granite) stone should be compared to speaker’s weight?

Intuitively, it makes sense to use a stone that is heavier than the speaker.

What do you think?

Another science related question regarding stones: How compares granite’s own frequency to the audio related frequencies? What is the ideal frequency/material for speaker stands/decouplers?

(Just an attempt to get a bizarre thread on course to something useful).

I'll leave it to the scientists to decide what laws of physics might need to be called on here. But it looks very much like richard is hoping Poe's Law applies. I'm not sure he's succeeded.

Why would you want to do that?

Used to work in a lab way back when our analytical balances were analog. They sat on one of these as the place was full of vibration from machinery. We had to pass calibration which always happened on this table. The floor this sat upon had obvious vibrations felt in your feet. So massive granite works.

 

[svart-hvitt]

Yes, and I believe density is one part of the equation:

Could the other part of the equation be «material frequency»? I don’t know anything about that («eigenfrequency»)!



And if you want to avoid resonance in the material sneeking into the speaker, you’d need some petroleum products, like these? Thoughts on stone and petroleum for mission-critical audio applications?

Forget large masses and sorbothane.

What we need here is a superconducting maglev table to physically isolate the components from the ground.

I suppose a superconducting magnetic table can be thought of as a type of 'stone'...

Oddly enough, my colleague & I were discussing the use of crystals to align our audio chakras only hours before I read this thread... We were also discussing the possibility of superconducting speaker cables; none of your common-or-garden unidirectional, oxygen-free copper rubbish.

For DACs?

I hate to tell you that these might have been OK for analytical balances (until the electromechanical isolation bases came along). They rely on having huge mass but offer little or no compliance to accomplish isolation. I had two installed for use with ultramicrotomes, we found that they were inadequate. Have you ever watched the surface of a mercury pool sitting on one?

After listening to The Don re reporting people behaving strangely, I believe some audio forum administrators will be rather busy thus.

<Warning: humor attempt:>

Why do ultamicrotomists never attempt to have a discussion?
Because they are both really good at splitting hairs

I find humor more difficult than cutting remarks.

Subjective anecdotal report. You could feel vibrations in the floor with your hand. You did not feel vibrations on the table top with your hand. The balance on an adjacent slate counter would not settle down to the last digit. On the granite no problems. So it was helping in some way. The floor was ceramic tiles on a concrete slab.

I use diamonds. You must use natural organic diamonds, though, as the cheap industrial man-made ones cause the sound to be too harsh and mechanical. And for best sound they must be flawless but that does come at a price premium. The best sound is worth every little hundred thousand dollars, however.

Pffft, everyone knows if you want organic sound you have to use limestone. Its made from ancient sea creatures, that once had a full spectrum of marine sonar waves traveling through their shells that affects not only the tonal qualities, but the plankton of your source.

Interesting. I'm curious, what is the "black material" under the top of that table? It is some sort of foam, or shadow from picture?

You should hear what this rock infuses in my rig.
