Hi Tboo I did the upgrade from standard kevlar cones to Stillpoints Ultra SS to Ultra 5 under ny Rockport Hyperions.
i can tell you, that this is the a very very good tweak.
I already had a combination of BDR shelves and the source together with the Ultra S with bases ( importaint) under all the upfront equipment as well as the hole gear is mounted on the wall and the speaker on the floor ( floor and walls are not direct atached to each other but separated with polystyren insulation, to avoid cold bridges)
The result was increased resoluiton, much finer taxture and extraodinary expancion of the sound stageas well as a more live articulation of the music. Very lively and adictive.
It is however very importain for the Ultra SS to have the correct hard surface underneath but this is relativ cheap to make experiments here. I also adtioned a set up with ProAc D100 speakers where the Ultra SS and 5 also made a emormusly positive diffence as it did for me. The Stillpoints are not cheap but compared to the effect the provide simply a must under ultra highend gear, after my opiniom.
So try them, they are worth it.
best regards
