Are linear tracking arms better than pivoted arms?


My answer to this question is yes. Linear tracking arms trace the record exactly the way it was cut. Pivoted arms generally have two null points across the record and they are the only two points the geometry is correct. All other points on the record have a degree of error with pivoted arms. Linear tracking arms don't need anti-skating like pivoted arms do which is another plus for them.

Linear tracking arms take more skill to set up initially, but I feel they reward the owner with superior sound quality. I have owned and used a variety of pivoted arms over the years, but I feel that my ET-2 is superior sounding to all of them. You can set up a pivoted arm incorrectly and it will still play music. Linear tracking arms pretty much force you to have everything correct or else they will not play. Are they worth the fuss? I think so.

Dertonearm, if I understand you consider a short arm to be the Achille's heel. I can only offer anecdotally that the shorter I adjust my tonearm the better it sounds. I can think of no explanation other than that improved resonance control of shorter arm is of greater importance than maintaining absolute VTA. Designers of top pivot arms obviously give much thought to controlling vibration with particularly elegant arm tube compositions. But it is remarkable how many long pivot arms appear to be casually designed in this respect.(Based on appearance I would include Thales in this second group. I would also include any arm with a detachable headshell.) But all things being equal regarding arm tube composition, a short arm should win at least with respect to vibration control.

Taken from another angle, is it conceivable that micro-variations in VTA(which long pivot arms also suffer albeit to a lesser extent), are any more detrimental than out-of-tangency tracking errors with pivot arms?

Finally, what pivot arm approaches a linear arm in clean portrayal of inner grooves?
We need Jonathan Carr to chime on in this discussion. He designs cartridges for Lyra and used to post on some audio forms a few years ago. But, i can't remember which website.

I be he'd have a lot of insight to share on cartridge design, tolerances, forces, and tonearm factors.

Does anyone remember which audio website he posts on? I think his moniker used to be "J Carr" or something to that effect. For some reasons, I think he now only drops in on one of the DIY Audio boards.
Tzed: Welcome to the monkey house. Perhaps we can team up and ask Phil for tips on setting up our Southers.
Thanks Samujohn, should be a fun ride.
I had a B&O 4004 but it was plug 'n' play so obviously a very different beast to the Souther.
I love the idea that there is a human knowledge base available for question answering and advice.
My first hurdle will be mounting the arm to the table....
D-Mo,

I think the inestimable Jonathan Carr posted on Audio Asylum in the past.

Vbr,
Sam
