Lyra and OMA

Thank you all. I've learned a lot!  

HA, shame on me? I took too long to move on the Lyra and someone else bought it!  It was an 'open box'- I can't do a $3,600 cart. right now.

Plus... I was very much on the fence with adding mass to the arm as the solution to the lack of symbiosis described by @jcarr.  A few years ago I had only the F9e, and was buying a new stylus, Peter Green at SS, said I might try to add a blue-tac weight (measured 1@gm) to the arm. It didn't work for me.

The Korf discussion is fantastic:

It clearly shows the Why, which was part of my quest after @jcarr wrote to the subject. 

Thanks:

and everybody who helped me save $1,900 on a cart that's not right for my TT!

Let’s not leave out @solypsa . 

The century plus of experience was reflected in @jcarr statement to seek out an MC that sounds good on your arm. 

Effective mass and engineering resonance transmission and control are interrelated, within a small range the added bits can work, but not always….

I run both an additional weight / spacer w a Lyra on my Triplaner, and a Kuzma….

Enjoy the music all !

Experimenting with adding mass to a tonearm (presumably to the headshell) may help dynamics and low-frequency weight and extension, but doing so will also push the counterweight farther away from the tonearm pivot, which may trigger adverse side-effects such as reduced maximum tracking ability.

Pragmatically this may not be such a great concern, as on most LPs you may not notice any difference in tracking performance.

Nonetheless, the overall results will likely be better if it is also possible to add mass to the counterweight, so that the distance between the counterweight and vertical bearing can remain the same as with the unmodified tonearm, or be reduced.
