@larryi , high horizontal effective mass does not mean the cartridge does not move. It means it resonates at a lower frequency. The penalty for that is the same as it is for any pivoted arm and remember on the other side of this equation you have the much lighter vertical effective mass which is going to do exactly the opposite in the vertical direction destroying the bass and even causing feedback under certain circumstances. You can not separate the two. You are caught between a rock and a hard place.
@lewm , and that is the problem with the argument with a high effective mass being "OK" On top of that the slow oscillation of the cantilever at the resonance point is going to place the cantilever in a less linear point in it's travel increasing distortion and tracking problems. The market usually figures things out. No air bearing arm has ever gained traction in the market and I do not think it is because of the complexity of having a compressor. The Clearaudio straight line trackers are lighter but still cursed by the same problem on top of hygiene issues and people in general do not care for them. No compressor.
I also object to your coloring this as my "ideology." It is not my ideology any more than the sun rising in the east. You can hypothesize that this issue does not cause a sonic problem but the issue exists.
Finally, IMHO a good pivoted tonearm is going to function and sound better. If tangential tracking is your thing check out the Reed 5T and the Schroder LT. The Schroder in particular is genius. It accomplishes the goal of tangential tracking while maintaining similar vertical and horizontal effective mass and avoids the use of motors and compressors.
