Experience With Linear Tracking Turntables

Nice to know that one can set the numerical graduations on the AS adjuster of the SL1200G series to match the numerical magnitude of VTF and achieve what Technics deems to be adequate AS. Do Technics say what that is, in terms of grams of AS force? I'd like to think that some of the better Japanese tonearms that also have AS adjusters with numbers are set up similarly, but one doesn't always know that for sure.

'If you work with cartridge manufacturers and rebuilders a lot, as I have, they can see uneven wear on the stylus within a few months from new."

These are two very different statements.  I agree with the second one.  The first one, not so much.  I have to moderate what I wrote last night because it implies more than is accurate.  While it is true that I set up turntables frequently and have done so for decades, it is not correct to imply that I am seeing many at all for the first time after much use.  Most of what I see are repeats that I have set up myself, again and again.  Accordingly, the incident rate for seeing poor outcomes due to set up problems are approaching zero.  Rare issues involve things like the occasional mishap due to an over enthusiastic cleaning lady or an out of bounds grandchild do occur. Conclusions cannot be drawn from such one offs.  So it would be wrong to draw too many conclusions from my experience.  But back to your two statements above.  It should be stated that the down side to opting to use of either no or too little AS is that uneven wear of the stylus is a real possibility.  I am using 0 AS on my HW-40 with a Hyperion and monitoring it very closely.  I use a Wild-Heerbrugg M5 microscope to see very clearly how the stylus is wearing.  I also am monitoring tracking performance using the software AnalogMagik.  Between the two I should be able to pick up deterioration fairly early.

To return to the original OP's question (...ahem):

I have used the Eminent Technology air-bearing ET-2 tonearm with 4 different cartridges over the past 35 yrs. or so.  I would not recommend inferior linear-tracking turntables, but a high-end, air-bearing, linear-tracking tonearm can be quite satisfactory.  The ET-2 is a pain to set up, especially setting the tracking force.  You also have to have your turntable perfectly level for best results.  Your choice of cartridges is somewhat limited because of its high horizontal mass.  But with a compatible cartridge, it works superbly.  I don't have experience with other linear-tracking arms.  I've had no urge to change tonearms or my SOTA Star Sapphire turntable.

I owned the original Souther Linear Arm in the80’s & in fact went to Lou’s house in MA & saw his whole set up. It first was on a VPI & then a Sota  Sapphire. It could sound very good but setting & aligning it were a real pain as anyone one change affected every other parameter! 
 

Clearaudio bought his patents years ago & I believe still offer a pricey version of the arm.

i opted to go for a Basis w/ an SME arm which has since been replaced by a Basis arm many years ago now. It still sounds excellent w/ a good record & while different than my digital stuff( Innuos/ Bricasti), is equally enjoyable.
