Made my own 10+ kg brilliant pebble! Mass damping to the extreme! - Page 8

I just want to say that Lord Chaos's posts have been the funniest things I've read all day, and as ridiculous as this all seems, it can be sort of amusing if you ignore the lewdness that is thrown in there, if not a bit odd.

Thank you. I'm glad I was able to rock your world in a good way. Laughter is good.

I did some testing and it seemed like the weight distribution on top of the chassis gave a different sound. The smaller the pressure point the heavier and more solid the bass was. The white stone had similar bass size as the books which were heavier, but it gave fake clarity and openness. The eggs sounded the brightest and cleanest, they gave a little more vocal information because of less bass emphasis.

I liked the sound of the white stone inside the plastic jar the most. Without the jar the bass was too solid.

Big plastic jar: 50 grams
Small plastic jar: 30 grams
7 egg stones: 1100 grams
White ball stone: 1250 grams
Books: 1800 grams


The position on top of the chassis matters also, but it's going to be impossible to get any consistency in the testing. The books had the most consistent sound but it sounded little dull. But with the stones, weird stuff happened, sometimes they sounded bright and sometimes little smoother, but they never sounded dull.


The longer I tested the smaller differences I heard, until I couldn't hear a difference because of fatigue. I need to do long-term testing to confirm...

Why didn't I think of this, now it's all making since.

Have you tried getting a lot of smaller stones and arranging them like an AKG logo? Or would you have to go back to Turkey to get them?

The logo is more than for looks, it has special mathematical properties that may make the system sound better.

Just reading through this thread is making me itch for a(nother) serious impulse buy... So, when I tell my wife I'm spending $xk on some headphones, I can say, 'Well, look at this guy!'. It also helps that she has been to McManus's house - and she can't honestly determine who is crazier...

Patrick: You go gurl!

Brilliant Pebbles - best of both worlds?

I did some more testing and weird stuff is going on with the eggs now! They sounded smooth now. It sounded like the best of both worlds. I got more low-level detail and it sounded smoother than the white ball (without plastic). It seems like the position of the eggs had shifted inside the plastic jar, it's not consistent.

So then I realized that if the stones are even smaller you can get both the open and smooth sound signature, and if the stones are of different shapes it should be even better. I just found out the design for Brilliant Pebbles! Is Brilliant Pebbles the Valhalla of stones?

The books seem to make everything dull, it reduces the resonances but it also seems to make something worse in the process, it reduces the brightness by making it darker and heavier, but it's choking the gear instead of letting it breathe.
But with the Brilliant Pebbles, it's so light that it lets the component breathe while reducing some of the internal resonances!

I did some testing with Brilliant Pebbles and the improvements are far from significant. But without the bottle it sounded harsh and fatiguing. With the bottle it sounded silkier, similar to changing from RCA to XLR connectors (night and day). But the difference wasn't night and day, it was almost inaudible.
Maybe a bigger bottle is better, or more of the small bottles! Then the weight distribution on top gets consistent. I want dozens of these bottles!

Or maybe I should buy (or hunt the beaches of Turkey) these stones myself and make my own enclosure. Or maybe I should put the stones inside the chassis? Or even better, a new chassis entirely made of stones!

You make a very good point. If you stand in the center of the logo naked covered in the blood of a freshly sacrificed spring lamb you can envoke the god of high fidelity to babtise your system with his magic urine. Now that's a realistic tweak that we all know and use on a regular basis.

*edit: oops, didn't realize you were located in Sweden, lol
Well, there ARE other people in Sweden besides Patrick you know There's even people here who listens to headphones... so Patrick, arrange a mini-meet!

Only my wife gets to listen to my system, we will do it on our honeymoon.

Will she wear a wedding dress made out of ERS papers?

On topic, I don't think the effect of the stone is that far fetched. Many audio manufacturers claim that the casing is an integral part of their sonic design so why shouldn't a heavy stone on top of it affect the sound? There's all kind of audio specific stuff you can buy to place on cd players, speakers and such. And as Patrick said, since books for example normally can be found at home for free why not try?

there are tweaks which are exactly the same concept as this which you can buy. lesse here hold on

I just re-read Jonathan Valin's article, "The Title Bout In Analog Playback," in the December 2006 TAS, comparing the Walker Proscenium Black Diamond and the Kuzma Stabi XL. Great review! Among other things, I was awed by the uncommon mass of these contenders. The Walker is 304 lbs with its 75 lb lead platter, and sits on a 450 lb dedicated stand. The Kuzma is 176 lbs, including its 48 lb platter.

read this article it's an example of this kind of tuning using, dots, different types of wood and lead. even a mention of the particles in the wood box-stand for an amp!

In other words, Patrick is a bit weird even for this forum but he's certainly not alone in this regard. The audio world is as close to bibbity-bobbity boo magicland as we have outside of the Playboy Mansion these days. Why not wear a wizards hat and call yourself Frodo?
