Mono Cartridge Recommendations


I am looking for a true mono cartridge, as I am adding a second tonearm (Musical Life Conductor SE 10") to my Technics SP10ii table. My phono preamp is an Einstein Turntables Choice - so I am looking for a MC cartridge.  Considerations include:

  • whether the cartridge was truly designed for mono (cantilever only moves laterally, typically uses just a single coil) 
  • compliance (many mono cartridges have low compliance, which can chew up grooves of modern mono records (although I'll mostly be listening to older records)
  • stylus shape/size - I could use some guidance here....
My price range is $1-2k.  Currently under consideration is the VAS Nova Mono (has two coils in balanced configuration, output ~ 0.8 mv), and the Miyajima Labs series (all have compliance around 8, which is kind of low).  Can people who have experience in this area provide some recommendations with supporting information (why).  Thanks very much, Peter

Re hum. Yes the Miyajimas can cause hum issues. I have a Zero and while I love it you will need to solve hum problems

The best solution is to use a phono stage or step up with a ground that can be lifted. Either that or having a mono switch on your amp. The latter causes (in my experience using an ARC Ref40) a slight drop in dynamics. My Music First step up has a three way ground switch and this clears all hum issues. The other suggested solution of using only one channel still left me with hum (which is clearly out of phase in each channel as the mono switch cancels it)

anyway expect hum and expect to need to work on dealing with it
@folkfreak Thank you for that info.  I do you have A mono switch, made by KAB, and it is well-made, but it is outboard and requires more RCA connections to place in the circuit. I was concerned about loss of dynamics. One Miyajima dealer told me that the hum could be removed by disconnecting one of the ground wires, but it sounds like that is only a partial fix based on your experience. With the equipment that I have, I don’t think I could offset the hum without some loss in performance. Unless there are other ideas or perspectives?
Re groove wear with low-compliance cartridges. If the tonearm bearings are excellent, and the effective mass is appropriate, it's a non-issue.
As Robert offers a home trial and return policy the best thing to do is to try it out. And stop trying to chase a discount on Miyajima. Robert offers fair prices and good support, simply pick the point in the model line that matches what you are prepared to spend. Having a cable prepped to reject hum is worth trying, see Joel’s discussion here

this failed to deal with hum in my system but it may work for you
In the "old days", it was widely known that using a mono cartridge on a stereo LP was verboten or at best ill-advised.  Some vintage early stereo LP album covers even have that warning printed on the back, in fine print at the bottom right of the text.  This warning is consistent with the concept that a (vintage) true mono cartridge with very low vertical compliance might potentially damage the groove walls of a stereo LP, which encode musical information in the vertical as well as the horizontal direction. Whereas mono LPs produce no musical signal due to vertical deflection of the cantilever.  In those days, many if not most audiophiles owned mono cartridges as their main standby, so it made sense to make sure that those converting to stereo ought to use caution. Clearthink's sarcasm and bad manners are not at all justified. Not that such nastiness is ever justifiable on this forum.

However, in the modern era we have a plethora of new mono cartridges, only a few of which can be said to be "true mono".  Miyajima mono cartridges are some of a very few such cartridges available.  Most other recent production "mono" cartridges are actually stereo cartridges within which the channels are bridged one way or another to produce a mono output.  Such cartridges are likely to have decent vertical compliance, unless they have been radically revised from their stereo origins, and such mono cartridges are not likely to damage a stereo LP.  Whether or not a Miyajima mono (or any of the few other true mono cartridges) can damage a stereo LP, I do not know.  But Robin Wyatt would know.
