Yep, I figured this wouldn't be an easy ask!

As mentioned, I already have isolation platforms under the speakers, and I'm impressed enough with them that I don't intend to change them out. (On my suspended wood floor, the difference was quite noticeable.) I don't really need to move the speakers, just be able to adjust the isolation footers and fine tune the aim, so lifting in place is enough.
I'll watch for the release of the IsoAcoustics lift, and if that doesn't fit the bill, I may try the one I linked originally. (Perhaps I can swap the small head on it for a larger, flat one.) Or maybe I just find the local Wilson Audio dealer and see if they have one of the Wilson lifts that I can borrow/rent.
Thanks.
