Well, it should just reverse it. I'm mainly looking for if I can hear the difference - i.e. does the isolator pad make any difference.

Besides with the setup I've got (and no barriers bar sheets) this is the best way to ensure that I cannot tell wether the isolator works or not.

We've set it up, so I should have some results by tomorrow.

Watch this space!
