Integrityhifi TRU-GLIDER Pendulum Tonearm

Maybe someone else that has the Tru-Glider and can chime in but I’m having excellent results and flawless tracking.

Only one Tru-Glider user? C'mon!

I am trying to figure out how some of the claims are justified.  "Weightless"?  "No pivot"?  The arm and headshell MUST have effective mass in order to work with cartridge compliance, and it is clear from visual inspection that they do.  Therefore it is not weightless. There definitely IS a pivot with its center at the attachment of the string; it's just a sloppy one.  That reminds me of at least the early WT tonearms, which also claimed no bearing, when in fact they had a pivot that was just not close tolerance.  And that headshell...  Does it really work without any friction? (If there is any friction in its lateral movement to maintain tangency, then there would be at least a small skating force.)  Anyway, all of that said, I have heard other oddball tonearms that cannot meet the claims of their makers yet sound great.  So I would never say without hearing this one that it cannot sound great.  Lord knows, no orthodox pivoted tonearm is perfect.

Well that's the "problem" lancelock...you have actual experience with  the tonearm! I mean, how can you possibly judge its performance unless you have some sort of engineering experience with no need to hear it?
; -)

Several times I have wrestled with Mijostyn's statement: "A tonearm must be limited to 2 degrees of motion. It must be held rigidly in all others. I will never personally consider an arm that is designed otherwise." I think by this statement, M is meaning to indict unipivot tonearms in favor of gimbal bearing tonearms. But the principle is poorly stated. I gimbal bearing will fix motion at the pivot in two dimensions, up and down and side to side, but at the other end of the lever, those two dimensions are always additive and permit motion of the headshell /cartridge in all directions in the vertical plane, with respect to the center of rest, just as with a unipivot. Indeed that has to be the case, else gimbal bearing tonearms could not track a flawed LP that has a slight warp and is also slightly offcenter.
