Rwd,
The Ref's VTA/SRA adjustment is on the fly.
It is less convenient to use than a TriPlanar or JMW because it requires two small hex wrenches, one to loosen the set screw and one to turn the adjusting screw. No knobs.
It is less repeatable than a TriPlanar because there's no scale of any sort.
Once a Ref is set up it will stay set up, but that doesn't mean you can just "set and forget". The cartridges likely to be paired with these arms are remarkably responsive to small adjustments. To maintain optimum performance requires frequent fine-tuning of VTF. Adjustment of VTA/SRA for every record, or at least different thicknesses. This will be equally true with a Reference, a TriPlanar or any other top arm, depending on the preferences of the user of course.
