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.

My sincere apologies to you Timtim. I assure you that is was NOT my intention. Way up in this thread, Emorrisiv wrote "keep it coming" in that he wanted to have a dialogue re. isolation, etc & I posted with very good intentions. Since then I'm afraid that we hijacked your thread. I think that the thread is badly scarred but we might be able to limp back to your intentions for this thread (I hope).

Good to read that you've had very good luck w/ your isolation technique w/ your integrated. I believe that the technique you are using is sound & will yield good results.

Well, it's not really a big deal. At least you guys stayed civil for the most part ..LOL
I just hate to have a thread written off as useless, when the original tweak has done so much good in my system.
So let me throw out a few more thoughts: While there is a TON of BS hype in the world of audio tweak advertising, Gingko has labratory results to back up their cloud platforms. They even have shown real time vibration comparison results on HUGE screens at national A/V events. Take a look at their website for real world experiments with empirical data to prove it.
I think we "audiophiles" sometimes keep looking for the next great thing, when in truth it's already been tried, proven to be successful, and passed over in our over zealousness. The platform under my Lexicon is literally night and day, by a huge margin, and with ZERO psychoacoustic mentality muddling things. Yes ... I have done blind listening comparisons with my family and friends, even if they did think it excessive .. LOL

Timtim, I am glad you like the results you achieved, especially for the dollars invested. Just remember, since you've touted the Gingko results, raquetballs are not Gingko balls. Sometimes we diy-ers get pretty close, sometimes not. If you ever get to hear a comparison in your system let me know.

Racquetballs turn vibrational energy into heat VERY well. Those who know this are listening with a grin :-)
