Welcome to the tweakend!

@dekay 
My system is in Flux right now.  Are you talking about virtual systems? If not, where?

mijostyn,

BAT VK-30SE preamp on one, Herron VTPH-2A on the other. I may also try it under a secondary turntable I use for checking out used records at some point, but right now I don’t have a pile to check out.

georgehifi,

I may try that again at some point, if only to compare to the balls.

The trick is getting 6", 8" and 12" inner tubes and choosing the one that best fits the size and weight distribution of the component. Fill with 3-5 PSI and balance the component on the tube. I even went so far as to fill a 6" inner tube with 90 weight oil and that was trans-formative. However, I was concerned that over time the oil would degrade/soften the rubber and I would have a huge mess on my hands at some point. 

Now that I think about it, I wonder if water in the inner tube would be a suitable replacement??

Vinylzone, what are you planning to put on them?

I tried the inner tube thing back in the 90s. I found it just about impossible to balance components where the center of mass was significantly off center.

 Very easy, you need to "think out of the square", you buy an inner tube that is smaller, 2/3rd’s the size of the plinth it’s under and locate it more to be under the heavier section of the load. Inner tube is far better at isolating than thick rubber balls.

Cheers George

georgehifi,

I tried the inner tube thing back in the 90s.  I found it just about impossible to balance components where the center of mass was significantly off center.

The Raquetteballs do have thicker rubber, but it's still the air inside the ball that provides the spring.  And it's much easier to level a component with the center of mass was off center of the component.

A couple years ago I bought a box of golf balls (~ 8 x 8) to try, but never got around to it. The box will fit pretty well under either my Audio Alchemy DDP-1 or PS 5. Currently, both are resting on Machina Dynamica springs (as is all my kit), which are very effective

Just got my Amazon order. Picked up some nice some cans of
Raquetteballs, a dozen Sushi dipping dishes, and a couple of excellent quality maple cutting boards. Let the games begin!

Even better would have been "half inflated" scooter iner tubes under the bread board/s. Thinner rubber and air as the isolator.

Herron phono stage?

List your system (it's free and tiring - some of my updates never landed and I have yet to attempt adding them again).

DeKay

Yes, the BAT has balls, and so does the Herron.

Sounds good for dinner NOT for upgrading a stereo.

All of them!

He's trolling. He's had blue balls since forever.

Are the balls for your new BAT?

DeKay

Bingo! (the first one, well, maybe both.  We'll see)

I'll try and post some pics tonight if I get the chance.

Isolation platforms, or home made sushi and a game of racquetball?
