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!

hi tomasheig:
thanks -- i do believe that the modest mono cartridge will likely exceed the performance/satisfaction of the top stereo cartridge on a mono source ... but the problem is that the tonearm will also be lower quality and that could really affect things.

the match is the real question, as the tonearm & cartridge are a "system".

winegasman:
thanks much for the info. i was hoping to avoid any loss, but it may be that i have to go that route. if people threw up all over the idea, then i would want to avoid it.

the problem is that i have to buy a new armboard for my tonearm (~$2-300 -- pretty pricey!), so that kind of stinks. that definitely adds alot to the cost of the experiment and that is cost that cannot be recovered.

i could buy a mono cartridge to try on my current tonearm, BUT.... i wind up in the same position as when i started this conversation -- confirming what i already suspect (a good mono cartrdige can be better than a great stereo cartridge) but getting no practical info to help answer my real question about modest arm + mono cartridge.

I love my tonearm, but it does not allow for easy switching of cartridges. If that was the case, I'd probably purchase a 2nd armwand/headshell.

thank you!

Ebalog,

Another route to consider is getting a second table, one whose cost is about what you'd have to lay out for armboard and modest tonearm. Make that table your dedicated mono table for your experiment. Perhaps a Rega table with the 250 or 300 arm (if those are what you're considering)? Then pick up your modest mono cart. If you like the sound, you can sell the table/arm for not much loss (if you buy used, you might even break even!). Then you can make the investment in the armboard and 2nd arm with the full confidence of knowing that you like the sound you're going to get (unless, for some reason, the arm you choose is terribly mismatched with your table).

Enjoy the ride!

i really don't have the space for a 2nd table, but your suggestion is an interesting one as it certainly does minimize the potential loss and allow me to do a test in my own system.

my current table is very high performance, so i could expect that the mono cart + arm would do even better on my primary setup.

interesting though. many thanks!!

Hello Ebalog
I have a Basis TT with a Graham 2.2. I have two wands for the Graham arm. 1 for a Stereo Koetsu Urushi and 1 for a Lyra Helikon Mono. IMHO, this is one of the best investment I have made. I have found that this allows me to purchase used records I would normally pass over if they were stereo. As Eldartford stated in and earlier reply, a mono true cartridge does not send any vertical groove modulation information. This where most of the damage you here on stereo records happens. A stereo cartridge will send the vertical groove info to your preamp even it is in mono mode. The Lyra does sound better than the Koetsu for mono recordings even with my preamp in mono mode because of the missing vertical info. There are a lot of very great recordings out there in mono like the Beatles records, all of them up to the White Album were recorded in mono then channeled or remixed into stereo. IMHO they sound best in mono not stereo.
I would try the extra TT if I were you, that way you can get it used then sell it off. Then add the second tone arm to your current setup if you are happy with it. If you do the extra arm I would get the RB300 with the rewired upgrade and a Shelter 501. I heard it with my setup and it sounded great. Then I purchase the extra wand to complete my setup, I went with the Lyra because I wanted even better sound quality.
Do not use these mono cartridges on 78’s as this will destroy both the record and cartridge.

thank you, hevac1!

if you had to live with the rb300 + shelter 501, would you still elect to play all your mono records with it (on the same TT) instead of using your graham/koetsu combo (again, on the same basis TT)?

or would you use the koetsu for "clean" monos?

great info!
