I have a Triplanar, a ZYX Universe and a Transfiguration Orpheus. Neither exhibits even a slight amount of mistracking at the inner grooves. One day one of my cartridges died, and while it was being fixed, I used a Grado Green, which retails for about $35.00 or so. No inner groove issues at all, in fact it seemed to track as well as the other two cartridges. It took a bit of experimentation to load the cartridge, and after that it was quite musical.
What you can take from this is that initial setup, the match of the weight and compliance of the cartridge, in tandem with the effective mass and mechanical resonance of the resulting playback apparatus, is **everything**. If the arm has midrange resonances in the arm tube you could still get into trouble, and there must by no, nada, zero play in the bearings of the pivot!!
