Age old discussion I know but MM or MC? Benefits?

Uberwaltz, you’ve received a lot of excellent comments above. I would add that a good means of narrowing the bewildering range of choices you would have in going to an LOMC cartridge would be to choose one having comparable weight and comparable compliance to your present cartridge. In doing so you would minimize the possibility of a mismatch between arm and cartridge, since your present cartridge appears to be commonly supplied with your turntable.

Your present cartridge weighs 8.4 grams. Its compliance doesn’t appear to be specified, but the compliances indicated at vinylengine.com for numerous Clearaudio moving magnet cartridges are all 15 x 10^-6 cm/dyne, presumably at 10 Hz. (Cartridges manufactured in Japan typically have compliances specified at 100 Hz, and to equate those numbers to the 10 Hz specs used by European manufacturers multiply the Japanese numbers by a factor in the area of approximately 1.7, as I understand it).

That would seem to rule out the Denon DL-103 and 103R that were mentioned. Although their weights (8.5 grams) are very close to the weight of your present cartridge, they have 100 Hz compliances of only 5 x 10^-6 cm/dyne.

Also, while I’m not familiar with the phono stage you have purchased, and specifically with its noise performance, keep in mind that choosing a cartridge having a rated output in the area of say 0.5 mv is less likely to result in excessive hiss than one having a considerably lower rated output, such as the DL-103R (0.25 mv). I note that the description of the phono stage recommends a minimum cartridge output rating of 0.15 mv, but I would take that with some grains of salt.  It's usually a good idea to provide significant margin relative to published specs.

Good luck with your choice. Regards,

REG of TAS has forever been a proponent of MM cartridges over MC types.  This is not to say he is wrong, just to say that he has a longstanding bias that he maintained even when HP was gushing over every new LOMC entry from Japan, back in the 70s and 80s and probably the 90s.  This proves to me that in the end, the judging has to be subjective and system-dependent.

As always Al, your posts are very inciseful and contain many words of wisdom, as do the vast majority of the post already in this thread and I am grateful for each and every reply and the time and effort that goes into them.
I was of the opinion that a very lomc might not be a good fit and that possibly a medium output as you state or even a homc. Or stick with mm...or try mi....
Yes I have lots of great information now but still unclear of future path.
But that is one that at least is much more informed for sure!
Maybe at my level the present cart is more than good enough....but we all know the itch to try greener pastures.

Agreed that you have to be the judge. Cart choice must fit into your system and produce a sound you like. Other people's opinions are just that. This is a subjective hobby. 

A lot of people will say that to truly hear what MC can do you need to spend $$$. I have heard anywhere from 2000k to 3000k. For me that is a lot to spend on a cart that cost near the same price to re-tip and at some point will completely fail. 

I have heard MC up to about 1500 bucks and was not overly impressed. I prefer the Soundsmith carts sound and the their economics of re-tip. 

Also surprised you have not read that your phono stage was specifically developed with a circuit to work with the 20x dyanvector. People say with the enhancer circuit and the 20x you get a lot of performance for the dollar.

MM are great, cost less, gives more and you can look for the top carts mentioned by many users in the dedicated thread. No one knows which MM or MI would be the best in your system and it’s about personal preferences in sound. But the potential of vintage MM is huge, prices are real compared to MC. It’s always nice to get rid of all additional cables, suts, headamps etc, just to connect your MM to the phono stage to get the decent loud sound. Rare vintage MM cartridges will give you neutrial presentation much closer to the mastertape than most of the MC. The option with 100k load is also very nice to improve the sound quality.

MC cartridges are also good (often colored), but normally more expensive if you will get in count the price of the sut, headamps or high gain phono stages. They are more sensitive to cables, because the signal is so low. In the other words you can spend a lot to realize at the end of the day that your vintage MM is still better.

High Output MC are also not bad, i have at lest 2 of them.
I have MI cartridges as well and even very low output MM cartridge.

I was so disappointed with the very expensive modern MC cartridges, the prices are crazy and i can’s stand it, still can be fine for some people, but i don’t believe in the absolute cartridge, it’s always experiment, you never know.

I would avoid oldschool cartridges, conical tips and those broadcast denon 103 madness. MM cartridges from the 70s/80s are superior to the modern MM cartridges and of cource much better that oldschool MC carts.

It’s nice to have an alternative in the system (at least two tonearms with different types of cartridges). It is so much fun and always potential to find a better cartridge if you can compare them carefully.
