How good can a mono cartridge be...?


Can a modest mono cartridge better the performance of a top-of-the-line stereo cartridge?

I am wondering if anyone has practical, first-hand experience with this matter as I am deciding whether or not to invest some money in it. The situation:

1) I am luck to have a top-end tonearm and stereo cartridge
2) I have many mono LPs that sound great on the stereo setup (stereo cart, phono stage, 2 speakers)
3) My turntable will support a 2nd armboard, but my budget would not support a 2nd arm of the quality of my current arm -- nor would I be able to afford a top-of-the-line mono cartridge.

Question: Could a modest arm/mono cartridge actually perform better on mono source material than my top arm/stereo cartridge, all else equal? (No mono switches on the preamp, no mono amp, no single-speaker setup.)

What I'm assuming: If I could mount a top-of-the-line mono cartridge on a 2nd arm of the caliber of my first, then I would assume that it would perform better than my stereo cart on the mono source. Unfortunately, I could not afford to duplicate that setup, so I need to add that "practical" element to the question.

Said another way, on mono LPs...
a) Top arm + top mono cart > Top arm + top stereo cart
b) moderate arm + moderate mono cart > moderate arm + moderate stereo cart
c) moderate arm + moderate mono cart ? ( ?) top arm + top stereo cart

Has anyone experimented with this? Is it worth pursuing for me? I would have to get a 2nd armboard, in addition to the arm + cart.

Thank you!

Just wait for the "word" on the new Air Tight mono cartridge.It WILL be considered fabulous,but not cheap!I can say no more,without a contract being put out on me.
Best!
thanks for the responses so far. i am fully aware that there are many mono cartridges *AVAILABLE* (including $4K models), but i am wondering this specifically:

will a modest tonearm (say a rega) + a modest mono cartridge (say in the $500-700 range) perform BETTER on mono recordings than my (top-of-the-line) tonearm + (top-of-the-line) stereo cartridge?

i cannot afford to own 2 top-of-the-line tonearms and 2 top cartridge, but i am wondering if the modest mono combination would actually sound better on mono records.

can anyone help?

thank you!

Yes for the cartridge. Check out a Shelter 501 mono and you are there. A Mono Cartridge is for Mono Recordings and a Stereo Cart. for Stereo. To compare a cheap Rega Arm with a Top of the Line Tonearm is a different Story.
Try it with a Shelter 501 Mono cartridge, it is not expensive and you will hear your Mono's in a real good Quality.
Hi. I have a humble system so I can't tell you how the "modest" set-up will compare to your superb stereo set-up. Then again, no one from out here can honestly know what might "sound better" to you, since it's a purely subjective experience.

My suggestion, since you are curious, and since I trust that the curiousity will not disappear by itself, is to invest in the modest arm and cart that are in your price range (Rega arm and Shelter 501 cart?) and give it a go.

If it doesn't provide the satisfaction you're wondering about, you can sell both for modest losses. The psychic benefit of definitively answering the question for yourself will be well worth the modest cost.

Good luck!

[By the way, I have a tonearm on my table that allows for swappable headshells and for the past few months I've been using an Ortofon K-B ($1,200 sticker) for stereo and a Grado ME+ ($130) for mono and the Grado has pleased me more for mono -- quieter backgrounds and lusher timbre.]
