Acrylic headphone equipment stand with racquetball suspension *** photos ***

OK, here are the newest updates on my DIY Headfi vibration isolating acrylic stand. The changes I have made are to the shelves. They now have a space for mass loading with material of your choice. While sand and lead shot works well, I prefer the Black Gold material from Lovan. This development is a HUGE advantage, because it allows you to load the shelves at exactly the correct weight to keep the 10lbs per racquetball ratio. This is the ration that Gingko Audio proved to me the perfect weight per ball to accomplish the least shelf resonance, when using an accelerometer and seismic measuring machines.

The top shelf is temporarily filled with individual one pound bags of the Black Gold material, but will be changed to match the bottom shelf tomorrow. The bottom shelf has a black velvet bag inside of it, with the dampening material inside the bag.

The other improvement is the "fence" on the bottom of the shelves. This fence sits at 3/8" out from every side of the edge of each ball. This means if the shelf was to be bumped really hard, it can only travel 3/8" in any direction, before hitting a racquetball and stopping immediately from going any further.

This has been quite a project, but the difference in sound quality is not only astonishing .... it has been measured by scientific instruments, and proven to remove almost ALL resonance and vibration.

Cheers

I am surprised no-one has mentioned the bamboo headphone stand in the background .. LOL  Unless i am mistaken, that is unique. At least I don't believe I saw a bamboo stand in the "DIY headphone stand" thread.

Where did you get the acrylic?

LOL ... Someone did notice !   Thanks

Acrylic can be purchased from hundreds of places online, even cut to size. Problem is, the higher grade which is cast and not extruded is expensive, and shipping is rough due to weight. When I bought mine I lived in Boston, and there was a business there that ONLY did acrylic.

Tell you what .... it is more difficult to work with than I would have ever believed. Cutting it takes special blades that won't chip it .... drilling it takes special cut back bits that won't crack it. You don't really glue it .... it is really plastic welding, and you REALLY have to be careful with that process.
