Isolation Devices for Digital

If you want vibration isolation, use material that can undergo displacement and absorb vibration or dissipate it. Elastomers, felt, etc. are the usual materials used by engineers. Ball bearings and hard materials do nothing but transmit all of the incoming vibration. Using solid steel blocks instead of springs on your car suspension is something you would dare not do. Air suspensions are great for vibration isolation btw. Precision lab instruments are often mounted on them.

Mdconnelly, there is no such thing as drain. Now, having cones might change the sound for you but they do nothing except transmit vibration.

No Mdconnelly, a cone is not like a one way valve. It will transmit all the floor borne vibration that makes it's way up the rack to your component. There are places that will rent you a vibration tester. You can check for yourself what a cone can and cannot do. You do not have to take my word for it even though I deal with vibration issues on a daily basis as a mech engineer:) If you want to learn something about isolation devices, shoot me an email.

Likecoiledsteel, sorry, you cannot make a general statement like that. I have no doubt sometimes these cones affect the sources in your system, perhaps in a pleasant way but to call it an isolator, drain, whatever is not right. My question to you would be this: Don't you think by precariously balancing a cdp on 3 points, you might decrease it's stability and cause it to move more? I would urge you all to look up some real isolators online and see what they look like and the materials they are made of.
Tvad there is a good reason why air suspensions make good isolators. They can have super low natural frequencies, less than 10 Hz.

Jylee, ball bearings do NOT absorb vibration. I wish they did, it would make my life easier at work! Where did you get that from? What exactly do you mean by lateral vibrations?
