Star Sound Tech Sistrum Apprentice: Anyone use the 2.3" platform (SA-102-3)?

Everything I've found in reviews and forum discussions is about the 3.3" model, SA-103-3, so I'm wondering if there are any current or former 102-3 owners? I ask because with a Lampi tube dac and Supratek preamp (two pieces) the 3.3" total model leaves only an inch at most above the taller tubes to the shelf above. The 2.3" model is presented as the step up from the shortest model and also as a shelf topper, so I'm wondering what one might expect from it. Thanks,
Yes, the brass inverts are now effectively a required option across their platform lines.
As an added bonus they make adjustments of the speakers on the platforms so much easier.
I can imagine, although perhaps not where moving the platform itself is required. The Gaias, which I have under my active floorstanders, would seem a little easier in that situation. But for moving components in a shelving unit when dealing with wiring and such, those little caps would seem quite helpful.
