Linear tracking turntables, whatever happened?


Curious as to the demise and downfall of the seemingly short lived linear tracking TT.
Just from a geometry point of view I would have thought a linear arm should be superior to one with a fixed pivot that sweeps through an arc.
Obviously there is much more to it than that, sort of the reason for this thread.
I am genuinely interested in trying one out for myself as well.

The VPI ring clamp is not usable with the ET2 on my TNT6.

I would a take a chance on this if looking for a sub-$100 p mount. Part of the Azden cartridge line. The Azden YM-P50VL that I own is an excellent cartridge. In some ways I prefer it to my favorite P-mount the Acutex 420STR. This one is the same as the Azden YM-20E (elliptical stylus). New after market styli are available. For $50 and seemingly in good shape, seems like a no-brainer to me. Good luck.

Just want to second all that Chris has said re highest vertical inertia based on my experiences. As Chris may recall, early on in the history of his thread I mentioned that a few years previously I had constructed a long I beam fashioned from balsa wood. Due to the, not exactly state of the art, ways that I had figured out to attach the I beam to the bearing tube it was not a permanent tweak. However, the experiment showed me that there were sonic benefits in doing what he described; particularly in the bass. Frankly, at the time the notion of “highest vertical mass” was not what drove me to try it. It was simply something that seemed logical to try. One of the reasons that I love this arm is that it invites experimentation and I make most setup adjustments based on what I hear with the “theory” secondary. There is a symmetry to the visual impression that the arm demonstrates with the longer I beam that (not meaning to get too Zen about it) seemed natural. Maybe I just got lucky. I recently got two of Bruce’s new and longer I beams each of a different spring compliance.
Good question about a myth perpetuated by early “prominent” reviewers whose understanding of proper setup was limited. The ET2 gives me superior bass to any of the pivoting arms that I mentioned previously in terms of natural tonality and, most importantly, agility. Except, of course, unless one considers the overblown and exaggerated bass that the SME V produced in my system to be “better”. Now, re sounstaging? Haven’t had my coffee yet; so, later 😊
Very happy 20 yrs + user of a linear tracker, the great ET2, here.

First, while he has mentioned his thread, I think it should be stressed what a great resource ct0517’s thread is; not just for users of the ET2 to learn about proper setup and to get “outside the box” practical tips, but for anyone contemplating “going linear”.

By the time that I acquired my ET2 I had owned and lived with several pivoting arms including the SME V, Grado Sig, Sumiko The Arm, Premier MMT, Alphason and Syrinx PU3 (only one I still have). I have used more different cartridges than I can remember of both the MM and MC type and I consider myself fairly adept at tonearm setup, but far from a perfectionist in that respect. I still own several of those cartridges from way back and none have suffered cantilever or suspension issues due to use on the ET2.

There is no question that living with a linear tracker is more complicated than using a pivoting arm for the reasons already mentioned. However, once set up, I did not experience at all the need for constant fiddling and one of the beauties of this arm is that it makes the rare need for relevelling so easy. Which brings up what I feel is one great advantage of an arm like the ET2; I can’t speak for any other linear tracker as I have never owned any other. The ease with which the various setup parameters can be adjusted makes getting the best out of a cartridge infinitely easier in my experience. VTA on the fly is a miracle and I think many would be shocked at just how much just this one feature of the arm helps.

For me, the most important advantage of the arm is that, compared to all the pivoting arms that I have used, there is a fundamental difference in its sonic presentation that I find to be more realistic both tonally and in the way it portrays the soundstage. All those pivoting arms always left me with the impression that the shape of the soundstage and it’s boundaries were dictated by the arm and not necessarily what was recorded. None of them came close to conveying the sense of wide open ambience and stable layering of instruments that the ET2 is capable of conveying. The size of intruments and voices relative to each other always seemed distorted to one degree or another by the pivoting arms compared to the ET2 which tended to sound more realistic in that regard.  I also experienced far fewer instances of having a cartridge which had a tonal flaw that I could not live with which I could not make livable by adjusting setup parameters; adjustments which were typically far more difficult or impossible with the pivoting arms.

A very condensed account of my experiences only and I have no interest in presenting them as definitive; just one more bit of support for linear trackers. Happy New Year to all.
