Bo1972, I have raved about the StillPoints Ultras since the SSs first came out and then the Fives and now the Minis. Under speakers there is no question that the Fives are best, especially if you can get four in contact with your speakers. This is also the case under amps. I use two StillPoints Component stands which allow you to get all four in contact with the bottom of the amps.
The major concern with the Minis is as StillPoints says shock. You can break the ceramic balls that make them work. So if you have help with a heavy preamp, you can probably use them. Remember that you can adjust four to get all in contact with the component. If not, use the SSs. I've had mixed results with the Fives under preamps, dacs, and other source components.
But audio isn't easy. Star Sound Technologies has a platform, the Apprentice, that rivals the StillPoints Ultras and sounds quite different. I've had several instances in my system where I either had to really use the Star Sounds or preferred them. I think there is little question that they sound faster than the Stillpoints, but their sound stages is quite different than the Stillpoints. I will leave that to your tastes. Both products put to shame other isolation and coupling devices. I've got boxes and boxes of rejects.
Oh, and do not spray them. For one thing the spray may get on the ceramic balls and ruin their benefits. Second polish them into a mirror finish. I have yet to attempt this on the Minis but on the SSs and Fives, I got amazing results. I did not discover this, Tripoint did and told me to do it.
