Lower end Soundsmith cartridges vs others in same price range?

@mijostyn,

The effective mass of the cantilever can not be considered in the same way you would apply effective mass to a simple free-pivot tonearm, and the discussion in this article  http://pspatialaudio.com/analogy.htm#cantilever, highlights that.  The magnet mass and the cartridge suspension have significant impact.  The article models the mechanical components as a electrical model.

Otherwise, you can take what you wish from whatever you read.  

I have run The lowest price Soundsmith for a year and a Nagoka MP-200 on my other TT . Have even switched them.
The MP -200 is FAR better ! Both cost 400 $ .
TT''s were Pro-Ject Per.spect 6 and Rega  6 . Both of them cost the same .

Moving mass of Soundsmith is FAR less. So you have to change your mind. 
I do remind you it's moving cross from B&O stellar research times so it doesn't matter what you hear, it's proven by Youtube videos to be the best.

Nagaoka MP-200 has Boron cantilever.

SoundSmith Otello (if that was the lowest price SS) has aluminum cantilever.

Both cartridges comes with elliptical stylus.

SoundSmith is a mid compliance (22cu at 10Hz and can be ordered with high compliance 28cu too) while the Nagaoka compliance is much lower (7.2 @100Hz is about 12.3 cu @10Hz ! )

If they are about $400 then i have to say that a much better cartridges can be found for nearly the same price under $500 if you will look for a vintage MM or MI with better stylus profile like Stereohedron (Pickering XSV/4000) for example or maybe Grado XTZ MI with its Twin Tip for example (if you're lucky).
