Isolation Devices for Digital

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.

If your budget can accomodate it, try the Nordost Ti Pulsar points. They give the music a very solid foundation and help with detail retrieval.

I think that the cones used on equipment do drain vibrations, but it is not a one way street and can send vibrations back up as others have said. Thus, I find many people that use spikes, do so on top of another indepedent platform that is isolated ny a non-cone device.

The vibrations would drain down into the platform, while out side vibration cannot effect the platform as it stops at the non-cone device. Think of it as a cd player sitting spiked onto a wood platform that is supported by Vibrapods. Therefore both do as they are intended to, opposite functions.

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.
