Discuss The Viv Lab Rigid Arm

Dear @wrm57  : " If distortion be the food of vinyl, play on! "

Exactly and nothing wrong with that. It's for almost all our audio life what we are acustomen to enjoy.

My point is only, try not add more distortions that the ones you can't avoid in the analog medium.

I’m considering an experiment. The double-podded standalone tonearms have served their purpose in cartridge comparisons and are currently unused. It would take the drilling of just one extra hole in an SME 309-type headshell to mount a cartridge with no offset, and there is sufficient room for the cartridge to have its mounting bolts equidistant either side of a line from the pivot, so it will be perfectly straight. The pods can be placed at any distance from the table, so I could set it up as an underhung tonearm and see (hear?) for myself what that particular fuss is about. It seems that owners of the Viv Labs RF arm rave about it, whilst non-owners say it is impossible for it to be even acceptable. Someone’s got to be right.

Best of all, I have several spare headshells, and the one I alter will still be perfectly usable in a conventional manner afterwards. What’s to lose, except a little time and effort?

Each design has its drawbacks, so its possible that each design can be successful in its own right. I’ve never heard an underhung or no-offset pivoted arm, but it’s certainly an interesting concept so I wouldn’t rule it out.

The problem is that you’d be modifying an arm that was designed to be used with offset - just look at the differences in geometry between the SME and a ViV. So I think you’d be limited in whatever conclusion you could draw from the experiment.

Doggie, cleeds makes a very good point. Note that the bearing assembly at the pivot of the SME tonearm is offset to match the headshell offset angle. That would confound any attempt to use the SME as a test bed for underhung-ness. You could try it but probably should not generalize from such an experiment.

As for me, I continue to enjoy the 9-inch Viv I bought in Tokyo last year.
