Mono Cartridge Question


You chaps have watched me struggle with the issue of my London Decca Reference being irreplaceable, and then joyfully learning that John Wright has a successor after all. You have seen me buy and test three other MI designs (Nagaoka MP-500, Grado Statement3, Soundsmith Sussurro MkII) along with my older MC cartridges (Ortofon Kontrapunkt C and Benz Micro Ruby 3). Since those struggles have led me to owning two SME turntables and four tonearms, I am now torturing myself with the question of whether one of those four should be home to a dedicated mono cartridge. Remember, I only have one ear and cannot hear stereo at the best of times. A mono cartridge for my few dozen mono recordings would be a matter of reduced surface noise and possibly some improvement in dynamics.

I can get hold of an Ortofon Cadenza Mono (two voice coils so not true mono) for about 1600CDN, and a Miyajima Zero for 3450CDN. So the question is this: am I mad to even think about it? Money is not what it once was before I retired. There is no opportunity to go and hear these before purchase, without spending much more than purchase price on travel.

Shall I "make do" with my rather good stereo carts for my mono LPs or is there something better waiting for me when I get out those Parlophone Beatles LPs?

FWIW, for the past 20 years Lyra has been making mono cartridges with vertical compliance (but no ability to convert vertical motions into electrical signals) and line contact styli of similar dimensions as a microridge (the contact radii of our stylus measure 3um x 70um).

I will add that for a few decades our cartridges have possessed neither polepieces (conductive or not) nor any body structure in the vicinity of the signal coils, with both features being targeted at the banishment of eddy currents.
