OK...I've ditched my mono cartridge


Like many others I suspect, after the Beatles Mono release Box Set

I read a lot about the 'supposed' benefits of a true mono cartridge over simply using the 'mono' button in a phono-stage/preamp.
So I was persuaded to try one (without breaking the bank).

It's now been 18 months of listening and comparing the AT 33Mono

with all my other favourite stereo cartridges played with the mono button on the Halcro DM10 preamp.
Firstly...I'm not a fan of the AT33 sound. Compared to my short-listed dozen cartridges out of the 80+ I have owned, it lacks sparkle, depth, bass and 'life'...😩
Why have I narrowed down my worldwide search for the 'ideal' cartridge to a mere handful....to then just meekly accept the second rate performance of a 'hack' cartridge simply because it's a 'true' mono?
And why would anyone who has invested in a Koetsu Coralstone, Atlas, Anna, Goldfinger or Airtight for their stereo listening pleasure.....'step-down' to a lesser cartridge for their mono listening?
Oh...I know you can buy better sounding mono cartridges than the AT-33Mono.....but how many are you going to try to hope to match your favourite stereo ones?
Now that I've ditched the 33Mono.....I can listen to all my great cartridges with all their diverse flavours just as I do for stereo recordings.
And I never really did hear a special difference in the dedicated 'mono' one even though I half persuaded myself that I should...🤓

Everyone should reach their own conclusion.  My experience is that a mono reissue will sound different than a pre 1964 mono pressing, even when using the same cartridge (be it mono or stereo).  Mono cartridges will sound different, based upon construction.  A true mono cartridge generates signal from horizontal motion, only.  A stereo cartridge modified to become a mono cartridge will still respond to vertical motion.  Why is this an important distinction ?  Even though a modified cartridge is supposed to suppress vertical signal by summing, bridging, coil alignment, etc it is still there.  Unfortunately the existence of the vertical signal introduces phase anomalies that are audible.   It is easier and cheaper to adapt a stereo cartridge than to construct a true mono cartridge, which why there are very few.  At the low end there is the Denon DL102.  Anything better costs considerably more.  Some listeners swear by vintage Fairchild and ESL mono cartridges, that are more than 50yrs old.  However there are a few specialists that can rebuild them.
 
Unfortunately, the preamp driving one of my two systems lacks any mono switch (Atma-sphere MP1). I am thinking of replacing the function of its "phase" switch with a "mono" function
Lew, just so you know, we do option the preamp with a mono switch, executed using a custom rotary switch, often with a separate phono input. We've done tape EQ in this same manner.
Thanks thom and iopscrl for substantiating my perspective.

But let me phrase it a bit differently than I did before.  First off, I probably need to own more than a few mono LPs before I'll consider the trouble and expense of a mono cartridge.  Otherwise hopefully I'll have a mono switch on my pre or phono amp and be content.

However if I've purchased many mono reissues, better optimization may be worthwhile. If those reissues were cut since maybe 1990, they very likely were done with a stereo cutter head.  So choosing an appropriate stylus suggests a modern profile, whether it is in an "adapted" stereo model or a true mono design.

But then if I own a number of original mono pressings, produced with mono cutter heads, my stylus choice will likely be different.  Why would I not want a larger, conical/spherical stylus to better match the groove made by that cutter?  Also in this case I do not want any vertical pick up so that affects my choice as well.

Without beating this into the ground I feel it depends on how many monos and how they were produced that we want to listen to.

Pryso, This has been beaten to the ground on multiple threads and of course viability depends on a record collection. If someone has very good stereo carts and a collection of mono reissues, they will get performance beyond that of a stereo cart and a mono switch, with a high quality mono cart. This is with vertical compliance to play a modern reissue in a reasonable manner.

Even if vertical rejection is 30dB - same as a mono switch, the 45° groove wall has two sides, just like a stereo record. With a stereo cart there is always a difference between channels - output, phase, etc. That difference gets combined with a mono switch.

I can't say it's worth it for any individual user, but companies like Ortofon and Lyra make high end mono carts.

Regards,

Halcro, you state that you've had 80+ cartridges and then mention Anna, Coralstone, Goldfinger, etc.  Are these some of the stereo cartridges you've compared the A-T to?  Is that
