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.

D-Mo,

Thanks, I've actually posted to 2/3 threads! I think Albert has his Studer A810 back in rotation and hope he gets it revved-up for my next visit!

Now, back to your regularly scheduled programming...just playin' :-)

Vbr,
Sam

Happy to take questions. -Phil

Bravo! I will join you if I can afford this potential design, surely will be expensive! Thanks for sticking to mechanic discussion. No, you did not spoil the party. In fact, you have lively up the party. The great filmmaker John Cassavetes once wrote to a writer friend, “Energy bursts out of your writing. I've been thinking about you. The unknown adventurer. Blasting forth through concrete. Blast them. Then love them. Then blast them again...” You see, the blasting and loving is the same thing. Your passion for audio and science is applauded.

The Thales arm and the new sibling Simplicity arm look to have this potential but I do have concern about its extra bearings for the guiding motions to achieve geometric accuracy and hopefully not in the classic case of when the cure is worse than the disease. Regardless, I applaud innovative thinking.

Personally I have given up on the perfect tonearm. I like both genres, as long as people don't tell me their only reason for not liking pivot arm is because a linear tracker tracks more like the cutter head. Maybe I should just go digital. :-)

Just kidding!

This has been an exhilarating thread!

Hi C1ferrari, I had 2 professional Studer C-37 tubed stereo reel-o-reel machines with about 120 early Westminster, RCA, Mercury and others 2-track 7.5 and 15 ips tapes back in the 1990ies. The rock solid sound of a good r-t-r machine run with a great 2-track 15 ips tape has always been my reference for ohysical presence in sound reproduction. I abandoned r-t-r in the later 1990ies due to lack of supply in original tapes. Furthermore I could finally get the very same physical presence and dynamic from analog cartridge/tonearm and that did it for me. I got insane offerings for my two C37 Studer machines and the tape collection and let them go.
Hi Darkmoebius, I guess we would rather need graphs from spectrometers to show energy storage and resonance built-up in tonearm wands to illustrate the physical issues I was talking about.
Water decay and frequency sweeps will do for cross-overs and speaker building, but not here for tonearm/cartridge issues (or in case they really would do, the respective tonearm's performance would be so poor that it is hardly worth discussing at all...).
My sonic descriptions (I knew that would be coming back against me.... ;-)....) were done to "illustrate" the sonic results of the bearing rigidity and the mechanical problems in linear trackers.
Otherwise you will find very few sonic statements in any of my posts.
From my point of view (sorry for personalizing again..) the mechanical model and the resulting issues (and the lack of addressing designs..) are so obvious that its kind of frustrating.
