Dear Raul, According to every treatise I have ever read about the Tiptoes, the originals made of solid aluminum, they were not intended to be anti-resonance devices. They were/are meant to drain energy, but in one direction only. In other words, they are diodic in nature. If carefully placed at vibrational nodes on a shelf surface, they are supposed to transfer vibrational energy FROM the component INTO the shelf, but not vice-versa, ideally because the shelf is inert at the point contacted by the tip of the tiptoe. This has nothing to do with damping; it's all about dissipating energy. Using a stethoscope to survey the surface of a shelf, so as to locate the inert points on the shelf surface, I have observed this effect personally. If you don't take care to place the tiptoes correctly at vibrational nodes, then they lose their diodic property; energy can go in either direction, into and out from the shelf, and they are no different from raising your gear on alu blocks. The very best "tiptoe"-like device I ever owned were/are the Goldmund cones (no longer available). They have a core of amorphous damping material that feels like putty and an outer body of some dense metal. I still use them whenever and wherever it makes sense. One of the few tweaks I can actually "hear".
Were it not for the fact that I own and use an FR64S, I might take your critique very seriously, because "on paper" it makes sense. What I wrote above is based on my actual experience using the tonearm, and my experience is in contradiction to the theory you posit. Evidently, you had a different experience. This could be due to a difference in cartridge or headshell or in the construction of the tonearm mount. As noted, I am using it with an Acutex MI type cartridge; perhaps non-MC cartridges impart less energy into the headshell than do MC types. I am not using the FR headshell; I am using a lightweight aluminum headshell. Also, Halcro is using a carbon fiber headshell. For sure, this would make a drastic difference in the transmission of energy into the arm wand, compared to the clunky FR headshell and some others as well.
