Firstly , thank you for volunteering your financial interest in the commercial side of the audio industry
@robyatt , and in particular your somewhat pertinent business affiliation with Miyajima pick up cartridges , that said … perhaps you might like to take a look at section 13. Of the forum TOS , going forward.
You raise some interesting points with regard to tonearm symbiosis for both ? Murasakino and Miyajima mono cartridges , we have a number of members who have amassed considerable knowledge gleaned from hands on experience with these two mono pickups paired with a good number of disparate tonearms , who hopefully might care to add to the discussion , a few Viz: Mike L ,
@iaxel , bonzo ,
@jazdoc , and of course the OP , are already respondents.
It would be most interesting to learn of other makes and models of tonearm that have paired well ( and/or perhaps not so well ) in concert with , in principle the Sumile but also the Infinity since it has been made reference to and being a fine mono pickup in its own right.
I think it fair to mention that for the most part it would seem that transitioning *From* a Miyajima mono *To* a Sumile mono has proven to be a path fairly well trodden .
