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.

C1ferrari, Darkmoebius et al, JCarr is very active on Audiogon too...... see threads about Lyra and Fidelity Research Cartridges.
Dear Nilthepill, ++++++Another plus, IME, for linear arms ( that hasn't been talked about) is that they are able to track more readily than the pivot arms in case of playing a record with very low freq content (examples- techno music- Deepchord, Pole, Luciano, Patha du Prince,etc). This may be unique to my set ups. Let others chime in here.+++++
.... in your IME, but then you should give a listen indeed to some decent set-up (they even do not have to be set-up perfectly to show off) Graham P2, Triplanar or FR6Xs pivot tonearms.
Your personal impressions might very well change direction by 180°.
I for one did listen on the very same turntable with the very same cartridges, cable and all other periphery identical.
Especially in the very low level the linear trackers are no match for the very best pivot designs in terms of speed, inner details, maximum dynamics and tight, hard punch. Most linear trackers du built up a big, fat but soft and not really low bass which might sound fascinating with certain set-ups, but not if your woofers go really down and not if the set-up is able to provide air, freshness and color, speed and minute detail in the lower registers.

Still fascinating for me to watch the ignorance of the simple and obvious mechanical model and the resulting issues.
It is still IMEs and IMHOs, personal dislikes and choosing side by ownership. I had them - almost all. The day a linear tracker shows up which does address the obvious issues of the mechanical model, I am in the first group to buy it. And I will do so before any "sound report" or sonic description by anybody. Simply because it can be seen in the mere design of a linear tracking tonearm, whether it will perform up to the promise of the concept or not.
But by now I finally realize that I am only spoiling the party here.
Tonarm design is mechanics (static and dynamic) and geometry only.
Here is a lot of the old conflict between religious want-to-believe and cruel, yet plain, scientific research and description.

Not at all, I think most of us(even linear-arm owners) see your contribution as refreshing, insightful, and highly educational. Nor do I think anyone disagrees with your mechanical and physical description of the forces at work within the two discussed tonearm designs.

I think some disagreement may stem from your patent rejection of the subjective listening experiences of others while offering up your own as law.

Compare these responses of yours:

Individual - yet subjective empirical... - audiophile impressions versus mechanical laws.....

You are referring to days long gone by while using a phrase abused today. However - long term subjective observations are always subjective.
Logic - isn't it ?
With this statement:

As of yet, we've had no convincing(non-subjective) proof that properly set up, modern, linear-tracking tonearms actually:
a) cause premature or excessive cartridge wear/damage,
b) cause increased distortion due to excessive lateral force to the cantilever/motor assembly.

I have no doubt you PERCEIVE a pivot's greater "speed, inner details, maximum dynamics and tight, hard punch...air, freshness and color, speed and minute detail in the lower registers" versus linear tonearms "big, fat but soft and not really low bass" in your(or all) systems, but as you so succinctly said above
long term subjective observations are always subjective.
Logic - isn't it ?
Now, if you have frequency response and waterfall decay charts or the response by the two(or more) different tonearm setups in your room with the same cartridge, that's an entirely different ball of wax, altogether.

Regardless, I hope you will continue to participate in this thread, as your responses are the type that help elevate such discussions above the subjective "tit for tat" so often found on forums.

I have sent an email to Jonathan Carr(of Lyra design fame) inviting him to offer his insight into cartridge design criterion and tolerances. Perhaps his insight can help illuminate other aspects of this discussion we've yet to delve into and clear up some others. I would love to hear from some other cart designers, too.
Hi Dertonarm,

Thank you for mentioning Mr. Carr's contributions to AudiogoN...I'll review them. I'm fascinated by the discussion of free body diagrams and force vectors that are germane to this topic :-)

Somewhat off topic, but I'm rather curious...have you listened to analogue reel-to-reel masters (or close to them)? The sound is/has the potential to be exquisite and the experience - revelatory!

Vbr,
Sam

There are a few threads here in Audiogon's Analog forum dedicated to Reel To Reel playback"
1. Why Not Bring Back Analog, Reel to Reel Tape
2. Tape Project Tapes

And, Albert Porter who has participated in this thread has a discussion of his Ampex 351 Project

Do a search of the Analog forum for "reel to reel", there are a lot threads.
