I also use Aurios MIB 1.0's, three beneath each Clements RT-7 floorstanding speaker. The three Aurios MIB 1.0's rest upon marble ( I was at Home Depot, and forgot to use Granite) tiles supported by the original heavy metal bases from the speaker manufacturer. There is a flat rug with padding on wooden floor supported by steel beams (overzealous builder) beneath the heavy metal bases, and somehow, this all self-leveled the tiles beneath the Aurios. The transmission line bass thunders deeply, and pitch accurately, while the ribbon tweeter delivers musical, and extended treble output. So, I am in the floating speaker camp, and happy. When someone accidentally bumps against one of the tall speakers, and it starts to float back and forth, it can scare the uninitiated.
What's supporting your speakers?
I've had a lot of luck with Rollerballs or variants thereof under my electronics, including, surprisingly enough, a Power Plant. Seems like, in my system, the speakers just disappear a little bit more everytime I hit on a really successful tweak. i have ETC spikes under my Martin Logans right now, but was wondering if anyone has found a really great speaker footer.
