I am the North American importer of Miyajima Labs. I can tell you any true mono cartridge should not be used on stereo LP's as they have no vertical or up and down compliance! It is painfully obvious if it is a stereo LP when you play it with a mono cartridge. A good example is the re-issue Peggy Lee Black Coffee LP that has both mono and stereo tracks!
The Miyajima Mono cartridges play both original and re issue mono LP's sublimely. I suggest you read Michael Fremer's new review of the Zero he kept after the review (like the Premium Mono BE he used to use), and now uses on his vast mono collection. Nice thing is they have a 7 day money back trial. Arm matching used to be trickery but the Zero and Kansui make it way easier and now, even uni-pivots, like VPI are good! Harry Weisfield at VPI makes custom arm wands for the Miyajima's! He loves them!
