Best current footers for preamps?

IMHO, having tried over the years most of what is listed above, I like the Stillpoints Ultra Fives and Ultra Minis and very much the Star Sound Audio Points, especially the new 2.5 larger version. Both maintain the pace of the music, but especially the Star Sound APs used with their Rhythm racks. 

The Stillpoint Ultra also sound best with their ESS racks.

I have piles of ceramic, bad brass, aluminum, rubber, wood, plastic and steel, graphite, and lead feet. 

audioman58, a long time ago I had Sony likepole magnet feet and later a platform from Italy much like what you are talking about. 

Such devices behave just like springs.The Sonys were best as they did not slide to one side. They were about the size of the Stillpoints Ultra Fives.

I don't like spring isolators.
