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.

Dear @ct0517 : I admire your " devotion " to the ET but even that each tonearm has its own trade offs as I already posted.

In those times I bougth new a SOTA TT that came with the ET mounted. As a fact I did it due to really well regarded audio magazynes reviews. No I'm not an expert on the ET but now let me to ask you:

how many times did you listen ( at a good home dedicated  room full range audio sytems. ) the Rockport, Walker, Goldmund or Kuzma top TT's ? and which are the ET trade-offs?

@frogman certainly the SME V is not the best example for rigth low bass range, you can have better bass range for it but needs some tweaks.

Maybe both of you need to listen somewhere what I mean with the rigthnes on low bass range. Obviously the best way is in a live music event at near field position ( 1-3m. ) from the source.

I don't want to convice any one about and is only my opinion that even is not the main subject on this thread. So please ct05 do not make a " big deal " about.

Rauliruegas -
I am disappointed that you were not able to share technical information on how to get the best bass having owned the tonearm. I thought you learned on the ET2 thread about setup, even if you do not still own the tonearm. This is not an ET2 thread so I won't go into setup detail here.

The ET tonearm 2.0 and 2.5 versions, are standalone tonearms, designed to be mounted on many types of turntables. To say it was mounted on a Sota or other table, unfortunately does not tell anyone how you actually set up the tonearm "to perform". That's the info that is valuable. Bruce Thigpen, through his business partnerships arranged to have it mounted on a number of turntables. i.e. Sota, Oracle, VPI etc...

To answer your question I have heard the Kuzma Airline - same room with an ET2. An MC was mounted on an ET 2.0 and it was mounted on a different, what IMO was a lesser table than the Kuzma table that the Airline was mounted on ; so it was not an apples to apples comparison. Still it was enough for me to stay with the ET knowing what I knew.

Regarding Gear and classes of gear.
I have no devotion persay to gear. I can also talk passionately about my room, my speakers, amp, preamp, etc... I do run my gear hard - all hobbies - I keep the good ones and that is the end of it. The Gear are not trophies. The only thing of value is the Room/Space and the music; not the digital files - easily replaced - but my record collection.
   
I do believe that gear does fall into classes. For example assume a person owns just a regular Cartridge W, Tonearm X, and it is on turntable Y. If the person then upgrades the turntable to Z and keeps all else the same, and the results are much better. Then it probably can be said that the tonearm in this case, out classed the previous turntable. That's my opinion.

With that each time my reference turntable was modded to the better, or bettered with another table - it took my ET 2.5 to new heights.
   
The best bass comes when the tonearm is set up for the highest vertical inertia.

@ct0517 - I'm interested in your comment about setting the ET for highest vertical inertia. How do you accomplish that? I've had the Kuzma Airline for at least a dozen years and remain happy with it (the only issues have been compressor related and now that I have a relationship with the SIL folks here in Texas, I've pretty much solved that problem, though it does require more maintenance than a conventional arm). Bass? Not in your face, thwacking slam. But if it is on the record, you will hear it. There is something very 'unmechanical" sounding about these arms. I did have an ET that was given to me many years ago, but never got around to setting it up. Herb Wolfe, who only recently passed away, was supplying a lot of the pumps and hardware to the NY audio mafia back in the day. He was a very cool guy. 
The ET is a phenomenal tonearm and I can’t believe it sells for as little as it does. It just pulls out that much more natural detail and subtle soundstage cues which tells me it’s allowing the cart to do its job. 
I run a portable construction compressor into a water separator into a regulator. It provides me with a half hour play time with a 2 minute run time. Arm is rock solid, never goes out of adjustment. 

Chris’ (ct0517) assertion that high vertical moment-of-inertia produces the best bass is to me, a user of London (Decca) cartridges, VERY interesting. That cartridge exhibits far lower vertical compliance than horizontal, which aligns well with a pickup arm exhibiting higher vertical m-o-i, no?

@analogluvr, I’ve said it before, and I’ll say it again---Eminent Technology’s Bruce Thigpen is as brilliant a hi-fi designer as there has ever been, including Peter Walker!
