RE: Looking for Ideas and Advice on DIY Component Suspension

I had a long conversation the other day about this type of vibration control concept.

Me too, coincidentally. I was in contact with the inventor of one of the commercial isolation bearing devices. He mentioned that he is now suspending his turntable in this fashion and is perhaps interested in taking the concept further.

While this method isolates the device from a rack shelf, the device is still vulnerable to airborne and self-generated resonances/vibrations.

Yes, of course this makes sense. And moreover, by eliminating "drainage pathways" (in the form of cones or spikes or the like), it would seem that airborne and self-generated vibrational energy really has nowhere to go. Not good. This is why I selected just my DAC for my initial experiments. At roughly 30 lbs., it's truly built like a tank ... with a chassis that was machined from a solid block of aluminum, I believe; that is rounded on its sides to minimize vibrations; and that was treated pretty extensively inside with anti-resonance/vibration material. To take the opposite end of my component spectrum, I wouldn't dream of suspending my amp or pre-amp (with their much-less-robust enclosures) in this way, as I think that the loss of "drainage" would be very detrimental.

The other aspect of a suspended component by a strap attacked to the ceiling is the component is now coupled to the ceiling with its own vibration control issues,some which can be much more vs. a rack shelf.

In that case, it sounds like my inability to utilize my ceiling -- and my need to utilize my rack in some way -- might not be the downside that I thought it might be? Does one of my three ideas -- i.e., long bungee "loops" around the shelf above; a strap-bungee hybrid around the shelf above; or bungee cords secured to solid steel rack uprights -- appeal more than the others? Do any alternative designs come to mind?

Does your system involve the very thick maple boards and massive brass footers shown in the image?

Yes and no. That photo illustrates my rack's basic skeleton -- the Mapleshade Samson rack with 2" solid maple shelves. (Mine has five shelves as opposed to three.) I do not, however, use the separate maple isolation platforms. For one thing, I don't have the vertical space. As well, I don't couple any of my components to their shelves with brass footers. I'm currently using a couple different isolation bearing devices ... specifically, Aurios MIB devices under my transport, and Rollerblock Jr.+ devices under (and bolted to) my DAC. My amp and pre-amp are on some generic cones but would probably benefit a lot from something better, and I'm thinking about starting over. (Your carbon fiber discs are coming! We'll go from there...) Turntable up top is on its own separate maple platform (mainly because of its size), and I'm experimenting with different materials between the top shelf and that platform. Finally, the entire rack does sit on four brass footers directly on the floor. Perhaps it should be isolated from the floor somehow?

Duster, "cheers" to you! Your comments are always very welcome!
