Best Isolation Devices?

You'll never be able to fully isolate a component that is in the same room as the speaker system. Nor will you ever be able to transfer all of the energy that the device generates or picks up to another device. Some energy will remain with that component and / or be reflected back to that component. Anybody that tells you something different either doesn't understand the basic laws of physics or has some type of agenda.

The best that you can do is to reduce the ampitude of the resonances / vibrations that the device generates or picks up and try to spread them over a wide frequency range. At the same time, you have to think about minimizing the potential for the devices being used to achieve those goals contributing their own sonic signature into the system. They can do this via reflecting the energy that they were not able to effecively absorb or pass on back into the device OR coupling other outside energy back into the system. After all, anything that is coupled to a device can transmit energy in both directions. While the energy transfer might not be equal in both directions, denying this fact would be nothing short of silly.

Having said all of that, please do a search in the archives regarding coupling and / or isolating. You'll find a wealth of information both here and on Audio Asylum. Sean

Thanks for all your input and sorry for the bold print of my origional post. I was frustrated in experimenting with different tweeks and forgot that it's about having fun and enjoying the music. After all it's only a hobby.
That being said I discovered that by putting better cones on my PS Audio P500 the sound dramatically improved. I did not believe the ac conditioner was as influenced by isolation as it is.I put brass under the PS Audio and BDR cones#4 under the power supply of my preamp and that seems to work for now.It's fun to be able to manipulate the sound of my system by simply switching cones around. I guess it's about trial and error. As I'm reading more posts on Audiogon I'm realizing that I have tons to learn about audio but that's OK as I'm always willing to learn. Thanks

Would an isolation shelf be significant under my Titanium cones under my CDP? My CDP is on Titanium cones and directly on the top shelf of my Atlantis rack. I'm thinking of putting an isolation shelf under the Titanium cones on the top shelf of my rack.

experiment till you find nirvana. similar to sidssp who used an inner tube, i placed a few of those air filled packing bags (about 4in x7in under my cdp. Imaging improved, bass improved, some detail improved...all to a fairly substantial degree...high end extension such as brush work on snare and some symbols vanished completely. a combination of metal and rubber cones under my tube pre with the pointy end up helped the imaging there with no adverse affects. Wish i had more time to chase the ultimate
