Hi Pete,

"I think for some reason you've filed Oddmanout's comments in the same category in which people believe the cones/points are isolators (or mechanical diodes) and not couplers."

In my post, I responded to the statement saying "They are desighned to drain vibrations from the component to the shelf." and didn't "file" the statement with those made by anyone else. Your disagreement suggests that coupling the component via such means will allow vibrations "to travel to the shelf where those vibrations can potentially be converted to another energy form." This presupposes a systematic approach utilizing some kind of absorptive material below the cones. I agree, especially with your use of the word "potentially". Whether converting the vibrations emanating from a component to another energy form after providing a means for said vibes to travel to another object leaves the original component with fewer vibrations is something I would tend to doubt (since it will continue to generate them), though I can easily see how the sound would *change* by coupling the resonant characteristics of two objects.

Where I do not agree (and please notice I used the words "in my view") is with the concept of "draining" which is not the same thing as providing a conductive path. I can put a pipe between two tubs of water and that pipe will provide an effective means for the water to travel from one tub to the other (in either direction). This however, isn't the same thing as saying that pipe will necessarily "drain" water from one tub to the other, regardless of the shape of the pipe.

Further, to my mind, the concept of draining implies something will be removed, leaving behind a smaller quantity of that something than before the draining was applied. So, again from my perspective, what we've created is a conduit and nothing more.

"...Vibration management is a combination of isolation, coupling, and damping techniques..."

Though I frequently enthuse about isolation, I don't believe I've ever said anything that would suggest I don't agree with that statement.

I don't know if you've ever seen it but the link below will take you to one of the better articles I've read regarding cones (or spikes, arrowheads, nails, etc.). I've found much to agree with in this article and hope you find it interesting.

Happy Listening!
