Discuss The Viv Lab Rigid Arm

Lew and Dave: The Viv armtube can slide back and forth in the direction of its length through the housing by about 1mm. It can rotate around the axis of the tube a few degrees and it can be lifted a couple of mm to the top of the housing, tho here it takes some lifting to oppose the magnetic force of the fluid--not likely to happen during play.

Thanks for confirming.  I suspect it is this additional ability for movement that plays a big part in the arms response to and recovery from movements that cause mistracking.

Maxson, First, thanks for your response. To your direct observation, does azimuth remain stable over the course of traversing an LP during play? The top surface of the headshell on a Well Tempered Reference tonearm, for example, visibly rolls over toward the spindle as it moves from outer to inner grooves.

@lewm I've never seen the arm roll as you describe. It takes a bit of twisting on my part to get it to leave its upright position.

That’s good, thanks.
