New Schroeder linear tonearm, any thoughts?

The error in my thinking: Yes, the effective mass is high in the horizontal plane, because of all the paraphernalia necessary for the LT function, but it is only affected by the masses of the arm tube, headshell, (cartridge), and counter-wt, in the vertical plane. Many tonearms are similar in that characteristic.

Hi, and this arm when properly set up (just once during installation) has a ever so slight tendency to want to move to the inner groove...a slight breath sends it on its way...if you have the stylus on a blank record...so not much mass or nearly any force needed for it to trace the grooves...

Hi,
The eff. mass was stated as ranging from 14-21gr. since one can exchange the Certal cartridge mounting plates for lighter or heavier types(phenolic, brass,etc...), just as on my "old" arms.
The eff. mass is only about 20% higher in the lateral plane vs. the vertical plane.
Why? Most of the additional mass(pivoting bar) is near the pivot AND the linkage isn't rigid, but the fluxlines will "bend" if accelerated swiftly(like when the lateral resonance is exited, which, for other reasons is nearly impossible in this design). At the same time, the magnet/guide bar acts a an eddy current brake.
"Conventional" linear tracking arms(not the Simplicity and some other pivoted tangentially tracking arms) typically have a 8-20 times(800-2000%) higher eff. mass in the lateral plane.....

Hope this helps :-)
Have a great weekend,

lewm: yes the arm, table, platter etc. However the tone arm collar (connecting arm to board) has a triangular structure is this has a ever so slight corkscrew arrangement ..so first point of triangle is highest..next point slightly lower and once again. Apparently this helps nudge.

again talking very fine adjustments here and the stylus/arm has compensated for this arrangement...

Not sure how I can explain it better....if you got to my system pics...the 6th pic on the top...you can see about 1/2 of this triangled thingy and one of the 3 fine set screws... http://cgim.audiogon.com/i/vs/s/f/1385427538.jpg
