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.
" Mono cartridges are less forgiving than stereo cartridges in many respects. They can put a heck of a load on a tone arm because of their requirements."

Actually more forgiving of pressing or condition defects.  Most noise is transfered from vertical content.  Most users of mono cartridges (modified for mono, or true mono) report a significant reduction in surface noise and audibility of surface defects.   However, some (not all) mono cartridges are lower in compliance than the average stereo cartridge, thus requiring a higher mass tonearm for best performance.  On the other hand, many have reported excellent results from using a Rega 300 arm with a mono cartridge.
