I never found any information regarding Etsuro compliance. So I did trial and error with my Etsuro Cobalt blue, finding out, that I prefer it in more heavy arms, not doing any measurement. Axiom was developed from a person (D Brakemeier), who still likes the FR64s and FR66s tonearm, so obviously the Axiom is in the high effective mass range.
And finally I like the Gold in this arm. May be I will find in the future a tonearm, which will fit even better, but so far and to my knowledge, I like this pairing. As my MSL siblings (Hayabusa, Sumile, Platinum) all liked the heavier tonearms too, there is for me enough choice of cartridges to use with the Axiom.
The Acoustical Systems Aquilar 10" has only 11g effective mass, maybe I will get this arm too, to have a better chance to listen to my higher compliance cartridges.
