Racquetball isolation platform perfection


Racquetball isolation platform perfection ... and DIY style to boot ! Thought I'd share with you my experiment that turned out working perfectly in my system.
Basically I copied a Ginko Cloud platform using $5 worth of racquetballs from Wal Mart and some 1/2" Birch plywood. I used a specialty grinding stone from a local tool store that makes a perfect 1.5" concave in the wood. Cinched it up in my drill press and drilled it down about 1.5" in from every corner, and went down about 3/8" deep. It's allows the balls to move back and forth by about a half inch, and when the top platform is added the CD player simply " floats " on top. just like an original Ginko. This EASILY bested several different cones I have in my collection, a set of Isonodes, a set of Symposium Rollerblocks, and a innertube isolation platform.

Total cost ? $15.

The bass is the tightest and most defined I have ever had in my current system. It made amazing amounts of good things happen under my Lexicon RT-20.

Try it for yourself, it was a winner in my system.

Racquetballs turn vibrational energy into heat VERY well. Those who know this are listening with a grin :-)
Way to go Timtim. I have not tried the DYI cloud yet, but I am trying to get the materials to do it. I did pickup a set of the Dmotto bearing stands and they work great,and were not expensive at all. I won them here on audiogon.
Meanwhile I am still searching for the plexiglass. I see that it can be ordered online but I would like to find it local shop. Do you have any photos of your design? I would love to see it.

As for all the arguing, it gets very boring to read.You guys lost me quickly.I really couldn't keep the logical order of the discussion from the boring scientific boasting and the even more boring rants and personal attacks.
This hobby like all hobbies creates children from adults and then loses the fun factor.

My apology to Timtim if I was the impetus for starting the whole mess. I have been intrigued by the Cloud and thought that it could be duplicated in a DIY project and was happy to read someone had done it.Keep up the good work.

This started off as a very good thread.
I would encourage audiophiles to try these.

I have implemented 5 black racquetballs placed on Vibrapods as the suspension for my custom dual Plinth VPI with Triplanar arm and Zyx cartridge. The balls fit perfectly into the VPI holes that are already cut into most VPI bases.

This is the best isolation system I have ever found, and I have tried quite a few by different manufacturers over the last 30 years.

It has zero vibration\sound coming through the suspension, and great dynamics as well.

If interested, please take a look on my "System" page, or email..

Have fun..
