David,
Let me clarify what I meant by “break equipment” in my previous response.
I believe that physical forces can cause changes to electrical properties of electrical components (resistors, diodes, capacitors, transformers, inductors) inside audio equipment which in turn can have an impact on the sound of audio equipment.
I also believe that one of the physical forces that I described above is vibrations.
If we agree on the point above, then let me define a vibration.
To me a vibration is movement which consists of two directions: forward and back, or up and down, or both (but for the arguments sake, let’s keep it one dimensional). Looking into one vibration further we notice that it is made up of acceleration and deceleration with a change in direction between them.
Which brings me to my point:
It is the change in direction, or rather the fast acceleration and deceleration, that exert physical forces on components inside audio equipment that change the equipment’s sound. So we need to concentrate on reducing their speed. I want to note that the vibration’s frequency is less important because that criteria alone doesn’t say anything about the acceleration and deceleration of the change in direction of that vibration.
Your point of vibrations being able to decay as fast as possible is valid but is in my view primarily for components that generate vibrations themselves. If my speakers create floor vibrations, than I am interested in preventing them from reaching my equipment. Now yes, some equipment makes its own vibrations and some equipment will vibrate because of air pressure caused by the speakers. In those cases your point stands, but I am personally not concerned with that scenario because I do not have speakers that can pressurize the room to such levels and I do not listed at those levels.
I also think we shouldn’t spend much more time discussing the impact of sub sonic or very low frequencies on audio components. My speakers cannot produce anything below 32HZ and they produce 32HZ at -10db in my room. I do not have any organ recordings and am not a big fan of classical or piano recordings.
My original question was on the theoretical differences between two types of vibration reducing/controlling devices that are currently sold. Namely, damping and coupling/tuning. After this discussion I am still unconvinced that the latter is the best way to go for my system.
