Dear @michaellent : Project designer recomend in its site the Ofrtofon Cadenza RED ( in this line the Black is trully good. ) that has lower compliance and higher weigth that the Kleos and its resonance frequency is around 11hz against the healthy 9hz in the Lyra.
Ovbiously that who knows best the Kleos quality performance is the designer but the 10" EVO must be really good tonearm for Project makes the Cadenza recomendation.
I think that you can try the Kleos. Resonance frequency is not all between the relationship in tonearm/cartridge, the quality of the design and builded results are important because around tonearm/cartridge exist several other resonances/distortions developed during playback.
For me always is better that the cartridge suspension sees a lower dynamic mass than heavier one.
About those " shortfalls " you posted in the other thread can or can’t appears, in analog world always are trade-offs nothing is perfect . I don’t know in the EVO/Kleos which kind of shortfall could appears if any.
Btw, phono stage quality performance is way critical because it’s the unit that has the responsability to handled the sensible cartridge signal adding and losting almost nothing of what the cartridge stylus tip pick-up from those LP groove modulations. As better your phono stage as better your listening sessions.
Regards and enjoy the MUSIC NOT DISTORTIONS,
R.
