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?

I have 1mil Miyayima Zero and it is amazing! So much better than stero carrridges on mono.

Mono cartridges simply work better on mono records.  Quieter, more presence.  The Miyajima is a true mono and would be the best choice of those you are considering.

All of you guys who extoll the virtues of using a mono cartridge on a mono LP, do you have a mono switch on your linestage?  And if so, do you hear a difference between the mono switch used with a stereo cartridge vs a mono cartridge?  My opinion is I get a large fraction of the benefit by just using a mono switch, and the trade-off with a mono cartridge is that the cartridge must compete against your stereo cartridge for overall SQ.  Thus with an inferior mono cartridge, you might taking two steps forward and one step backward.  (Or something like that.)

I may be in error here, but my understanding is that mono cartridges on mono records tend to reproduce far less surface noise. If this is because surface noise results from vertical movements of the stylus, it makes sense as the vertical movements are ignored. IF any of that is true, there is then the complication that a cartridge for modern mono recordings must have some vertical compliance so as to avoid damage to a stereo record played inadvertently. This may be why I see some mono cartridges (eg from AT) labelled as dual moving coil cartridges. I assume the innards are the same as in stereo versions, but the coils are connected to sum the output to both channels. Now if we have the 45° arrangement of stereo coils, but wired to output mono, surely that just does the same job as a mono switch on the pre-amp?
