Best Isolation Device for Speakers?

Has anyone had a chance to directly compare different speaker isolation tweaks? I am wondering because of the recent thread on the Sistrum stand. I know that many of these things have been discussed in other posts, but there is not alot of direct comparison among them. I suspect that most of these are excellent, so if anyone has some information on their specific sonic impact, that would be helpful. I have a pair of Thiel 7.2s. Some of the ones I am considering:

Aurios Pro
Sistrum Speaker Stand
Mana Speaker Stand
Stillpoints
Audiopoints

Thanks,
Rob

You need to call the boys at Starsound about the use of Sistrum with your speakers..You should be able to position the triangle of the Sistrum in a way that will not interfere with the driver on the bottom..They will help a lot. Even the use of Audiopoints 1.5 in will be large..Tom

Isolation vs coupling...I won't go there. However, if you want to isolate, nothing is better than suspending the speakers from the ceiling. Chains or wire, and perhaps monofiliament fishing line works. For even better isolation (from the ceiling) you could use bungie cords. Cheap too.

With the boxes floating in space you get acoustic isolation as well as mechanical isolation. IMHO the acoustic part is usually most important.

Sir I beg to differ. In your proposal there is no provision for resonant energy to leave. The resonance will come out the front the back the sides. You will have a 360 degree resonant pattern to augment the music..Tom

Theaudiotweak...Enclosures should be solidly constructed of "dead" material, shaped so the panels don't vibrate, (cylinders are good), internally braced, and internally damped. If the top/sides of your enclosure vibrate, even glueing the bottom to a concrete floor wouldn't help.

Of course, the real answer is to get rid of the box entirely: go planar.

What is the best material to put under the speakers? I've got some B&W Nautilus 803's and I can buy Sound Anchor stands for them. I've read that putting BDR IV cones under the Sound Anchor stands is an improvement.

Perhaps putting a 2' x 2' sheet of granite, tile, hardward would be better?
