Are linear tracking arms better than pivoted arms?

Sometimes I feel sad, when I read some posts that there are a few who are not satisfied with some expensive units. So much work from the Designers to sky the latest NASA secrets, the steal some dust from the moon from them to make better sounding bearings, all those friendly journalists who have only ONE goal, to help in the endless search of the best...
and then: We read something no one really wants to know, ok, maybe via private mail, but please, not in public discussions.
When I had my Airline/Triplanar/Davinci/Graham and-some-more I loved the click of the starting compressor, the first move from the Arm to remove the dust, the starting of sound when my cartridge touched the first groove.
I loved it, the respect I got from visiting audiophiles, here they saw, that I am a serious Audiophile. Great time.
After a while I discovered late in the evening that the most used Arm was not that one which worked with air. I asked myself, what happened?
Had it to do something with sound?
I am still on the way to find my answer :-)

Thank you, Darkmoebius
"Has anyone ever had a cartridge wear out more quickly or be damaged by this lateral force of a linear arm?"
I have used my Souther for many years. Two years ago I sold my old Audio Technica AT150ML and purchased a new Audio technica 150MLX. The Audiogoner who purchased my old cartridge was very complementary in his feedback post concerning the condition and performance of his purchase.
Now I know this is anecdotal, and I do not keep strict track of my playing time, but still, if wear were a serious problem it seems I would know it by now.

Has anyone compared recent linear and pivot tonearms on a 2-arm TT at the same time w/ the same cartridge for an A/B comparison? What did you notice?

yep.

currently i have 2 Ortofon A90 cartridges; one on my Garrard 301/Triplaner and one on my Rockport Sirius III. the one on the Rockport only has about 50 hours on it and the other one has about 125 hours.

there are no 'unusual' issues with the A90 on the Rockport. it exhibits the same performance advantages of any cartridge i mount on the Rockport.

my perspective on this 'issue' that linear trackers are somehow 'stressful' on cartridges is that i have seen none of that at all. as i mentioned in an earlier post in this thread i had a vdH Colibri (a particularly delicately built cartridge) on my Rockport for 5 years with zero issues. as far as other performance problems/limitations from linear arms, again, i don't see them.

not all linear trackers are the same. it's likely a much greater challenge to build one to work properly, but it can and has been done. as far as limitations of an air bearing in bass performance, in theory maybe, but again i don't really hear that either when the Rockport arm is optimized. i know Andy Payor certainly does not subcribe to that perspective.....but what does he know?

Dear Nandric, he means "tongue in cheek"......

DT and Atma-sphere, The Triplanar bearings are needle-type bearings, are they not? Hence I don't know how they would be comparable to ball-type bearings and whether the same quality ratings apply. Of course, they are not from Schweinfurt so obviously could not be so great. Did you ever see the movie "Twelve O'clock High"? Clark Gable and Gregory Peck play two US airforce officers based in England, and the whole issue is bombing those bearing factories at Schweinfurt, every night. Anyway, the stress on bearings in any tonearm is infinitesimal compared to, for example, a wheel bearing in an automobile or a crankshaft bearing. So I think bearings rated 7 and lower would probably not make an audible difference compared to bearings rated 11.
