New Schroeder linear tonearm, any thoughts?

Is it absolutely level?

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

So, since you may be listening, Frank, I have often heard knowledgeable people argue about the value or lack of value of having high mass in the horizontal plane. For those who do not like the classical linear tracking tonearms, their very high mass in the horizontal plane is given as one of the problems with such a design. For those who do like them, the same rationale is posited. Further, for the Dynavector tonearms, which also have a higher effective mass in the horizontal plane vs the vertical one, this property is given by Dynavector as an intentional design goal, said to contribute to superior bass performance. What do you think?

Hi,

" Apparently this helps nudge."...

Nope... it's just there to "equalize" all forces acting on the stylus. If it was some form of skating-compensation or -generation arrangement(to "nudge" it inwards), an increase of VTF would change the tendency to move either inwards or outwards. But it doesn't...
Kind of the same as if you were to raise VTF on an air bearing arm that isn't level. It wouldn't move/accelerate any faster if you were to increase VTF. Solely a question of gravity acting on the entire assembly.

Cheers,

Frank
