Scompracer, I used the very same Triplanar on my Hyperspace that I now use on my Nantais/Lenco. To mount the Triplanar on the H'space, I needed to have Tom Fletcher (Nottingham Analog boss and mentor) make me a special platform that raised the tonearm base to an acceptable height.
As to the question about feet for the Nantais/Lenco, when I bought mine, Jean had some threaded brass cones that were made for his projects. I bought a set of 3 for some extra dough, $160, I think. I've no reason at all to believe they would be any better than the Mapleshade cones or any other solidly made cones, but having the threaded attachment to the plinth is nice for height adjustment.
