Lyra and OMA

Tonearm has a lot to do do with how much you get out of your cart...

Ah ha! thanks for pointing out the difference between the Japanese standard and the US/euro standard dyne. A lot more compliant than I ever thought. No wonder cart we’re getting such apparent poor results. 
ready to do the real mouth now.

The math says…

The calculation says that the cartridge/arm RF is a very healthy 8.37 Hz. 
So my question is why does the low-mass arm make a difference in the sound?  If the mass were higher, the cartridge/arm compliance would logically be a higher resonant frequency also.  It wouldn’t pass out of the recommendation, but 8.37 Hz nice sweet spot, no?

a better calculator is imo the Korf which also calculates acceleration…. You do understand J Carr is THE designer at Lyra…… ?

I am pleased to hear that the Kleos could have more bottom end slam depending on the tonearm. In my Well Tempered Black Arm, the only thing I think could be improved is the bottom end slam. I was concerned that the Kleos was the issue, but seems like it could be the WTA.

On my LP12, the WTA and the Kleos work well, but with the issue described above.
