Audiophile Vibration Control Product Testing and Review - Part 2 - Sand vs Sorbothane vs Squash Ball

[@DickVanPaiton]

I would have loved to see the comparison with sorbothane half spheres which have the right shore value for the weight of the equipment.

[@AudiophileJunkie]

It's easy to do that test yourself or compare to anything you want.

Did you try your Squash ball idea with my Focal Aria (including sand filled stands). Incredible result. There is so much more room filled with music. Sound goes far over the speaker boundaries left and right. I used 5 Squash balls per Speaker stand but I feel they are too heavy overall. I will increase to 6. Did you ever create a Squash ball per kg ratio one could use as a guideline?

[@AudiophileJunkie]

Glad it worked. I didn't calculate exact ratios but I know Townsend has done that for their products. I usually just keep trying adding more balls and the geometry under the gear until it measures best.

+1 on sand filled stands. Mine are 3/16 steel welded and all crossbeams and legs filled w sand. Coupled to floor via brass cones. All equipment (mono’d tube amps on “shorty stands” at room null points, turntable, CD player, preamp, phono pre etc) are on these types of stands. All “shelves” are made of 2 1/2” hard maple. The turntable sits on a stand w a 350lb granite slab (isolated from stand by hard maple feet) on top of that is a 2 1/2” maple “shelf” that is isolated from granite by brass cone feet. The Clearaudio sits atop that. None of the shelves of any of the racks ever directly make contact w the metal racks. Minimum sound treatment in room (heavy insulated drapes, natural wool rug on hardwood floor). Super quiet background, large deep soundstage (near field speaker setup).

Thanks for the video, very interesting aproach! Do you have a link to buy the squash balls? I would like to try it on my system.

Good demo all the time！

[@willbrink]

Is that a rug you're testing on? That's going to make a major difference if it is.

Whats the duro rating on the sorbothane?

[@marcwilson564]

Hello. Loved this series and would like to do a similar set of tests in my listening room. What is the app you are using?

[@AudiophileJunkie]

Hamm seismograph

[@marcwilson564]

@@AudiophileJunkie Thanks. It took a bit if a search to find it. Not in the Google Play store. Works great!

[@saltzine]

"Double yellow" squash ball = least bounce (of squash balls) This equals more coupling to the floor? Their greater density means more vibration turned to heat?

[@AudiophileJunkie]

It's not a hard and fast rule to use the double yellow, but it provides a firmer base than ones that are too soft. You're trying to mimic the Townsend spring and bellows for both firmness and dissipation, so this seems to work best.

what is the app that you are using?

[@AudiophileJunkie]

Hamm seismograph, but there are many that can probably work just as well
