According to Jolida, the JD9 II phono stage provides 60 db of gain for 5mV input via the MM section, 75 db or 85 db, respectively, via the MC low and high gain sections, for lower input voltages. (I looked but could not find any data for the model III.) If the nominal output of the Hana SL is 2mV and assuming 60 db of gain via MM for 2mV in, the output signal would be 2V. That alone is more than enough voltage to drive most amplifiers to full output, regardless of the gain afforded by any linestage inserted between the phono and the amplifier. You could even use a passive linestage. So, I would say the MM section ought to be MORE than adequate. Mark, most amplifiers are driven to full output by 1V or more of signal voltage. You need to know the output of the cartridge (typically stated for 5 cm/sec stylus velocity), the gain of the phono stage, the gain of any linestage in the pathway, the input sensitivity of the amplifier, and the efficiency of the speakers, when making these estimates of how components will match in actual practice. OR, just try it.
As to the load resistance, that is a dance that never ends, but I routinely use 47K ohms into my MC stages and 47K or 100K into my MM stages. Every time I load down even a LOMC cartridge, I find myself preferring the "unloaded" state afforded by 47K. But that’s just me and my particular (Atma-sphere MP1, fully balanced) phono stage.
Nandric, It would be impossible for cartridge makers to follow any guideline for load resistance, let alone 47K ohms. First of all, most end users are brainwashed into believing that they need to use 100 ohms or thereabouts for LOMC cartridges, and they would be put out by not having that option available. Many phono stages use a fixed 100 ohm load, because it makes the customers satisfied. As you know, many modern phono stages solve the problem by providing a choice of loads starting at 100R and going out to 47K. Most cartridge package inserts state ">100 ohms", or similar ambivalent directions. As Ralph is fond of pointing out, the load resistance is more for the phono stage than for the cartridge, at any rate.
