When used with the optional Ultra base, should the Ultra SS and Ultra 5 be tightly screwed into the base or unscrewed 1/4 turn(as is recommended when the Ultras are mounted directly into speakers)?
When attached directly to an MDF speaker and unscrewed 1/4 turn, be careful not to lift the speakers by grabbing onto the Stillpoints device. This can rip the threaded anchor out of the cabinet.
In response to OP, I compared Ultra 5, Ultra SS, and Star Sound Audiopoints to stock Merlin points in my modified VSM-MX. Both Stillpoints and Audiopoints surpass stock Merlin footers. The isolating Stillpoints do a particularly good job on carpeted surfaces, where conventional points can't get a solid footing to couple as designed. In addition, four Stillpoints surpass three in every application that I've tried.
