Lyra and OMA

@michaellent  : Only take in count that the calculators in the net for the tonearm/cartridge frequency resonance takes the compliance at 10hz not 100hz. So, the Kleos has a compliance around 19 cu.

Btw, I own the Kleos and never heard the Songbird ( I owned 6 years ago the top of the line Sumiko. ) and I can tell you that the Kleos is an excellent quality performer.

Regards and enjoy the MUSIC NOT DISTORTIONS,

There are calculators and there is experience. Maybe JCarr knows a little ;)

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

@rauliruegas  

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?
