IMPEDANCE of MC Cartridges are not absolute, but there are guidance formulas and Maker's recommendations.
ANY MC Cartridge: do the math, i.e.
Hana before you choose between the ML and the SL
ML, slightly lower signal strength 0.4mv; much lower coil impedance 7 ohms; HANA recommended load more than 100 ohms. A bit lower would be ok, i.e. 70 ohms
Hana SL, slightly higher 0.5 mv signal; much higher coil impedance 30 ohms; HANA recommended load more than 400 ohms, a bit lower 300 ohms would be ok.
a SUT, best, one with separate adjustments for signal strength and impedance would be good, you could get a lower signal strength and the proper impedance.
You could use the SUT output with your existing MM Phono Input, where the RIAA EQ takes place.
And you would be set for future cartridge choices.
xFactors (signal increase) (you want a lower signal increase to use your existing chain)
.....................................
existing 5.5mv is too high (unless you change your Phono Stage)
Hana ML: 0.4 mv: if xFactor is 10 (+20db), signal is 4.0 mv
Hana SL, 0.5 mv, if xFactor is 8, (+18db) signal is 4.0 mv
....................
example of why separate adjustments for signal strength and impedance is advantageous:
My Fidelity Research has 4 optional choices, lowest is 10.55 xFactor; however the impedance is directly related to the xFactor and is 423 ohms.
Hana SL 0.5mv x 10.55 = 5.28 mv, too high for your existing set up, 423 impedance is good.
If ML, 0.4mv x 10.55 = 4.22 mv, a bit lower, perhaps low enough GOOD, BUT, the impedance is 423, much higher than recommended 100 ohms

Ortofon T30 SUT has 5 options, the results are like mine, none have proper combo of gain and impedance.
