Is a low output MC superior in sound quality to a high output MC??

To lewn,   That is a good point. My thinking on the issue of  the SS Otello cartridge with the U-Turn TT, is that platform and tonearm a worthy match up.  Consider the fact that a few audiophiles will invest in a "armless" table, and seek out the a seaprate tonearm compatible with the cartridge they want and have selected. This is understandable specialization like buying a separate phono pre-amp to insure the best performance from an analog set-up instead of using the phono stage in a integrated amp or pre-amp. 

My concern is getting the most out of a cartridge for the TT and  the arm I currently have. The only time I  purchased a separate arm for a table was in 1988 when I owned VPI HR19 Jr.and installed Audioquest PT-6 tonearm That was almost 30 years ago and audiophile market was  readily open to a separate arm and  an armless table. It was the mark of being a serious audiophile and/or vinyl lover. I don't think that is as  true today as it was 30 years ago. Many mid to high-end tables come with the brand's arm and many pre-packed  with a  decent cartridge. When you get above $3000, some brands come with their own designed arm, but generally NO pre-packed cartridge because they assume if you are paying for a $3000 plus table, you are probably going to install $1000-$2000  cartridge.

My other reason for me is I did not want to spend $479.00 for the SS Otello or possibly any cartridge. I can get any Denon HOMC or LOMC on e-bay for almost half their retail price which I know can be risky because it can be gray market junk or a worthless knock off.   

Let me work backward

To paraneer,  Thank you. That information is valuable. FYI, U- Turn's designer Ben Carter claims he has received several testimonials about the synergy between the Denon DL-110 HOMC and the Orbit Plus tonearm.

As far as the SS "Otello" I am not sure putting a $479 cartridge on a U-Turn table that cost me $409 including the their optional cork mat makes sense, but it is something to consider, if that is the best match up and will provide the best sound quality.

To willewonka,  Thanks for the heads up about the Moon LP110 adjustments; I have looked over the manual and understand the adjustment that are offered. Right now I am just using the "default" setting and did not have to open the chassis to make adjustments. 

To Chakster: Thanks for the additional info regarding the HOMC versus LOMC  issue.       SJ

The Moon tech said that the MM gain is high enough for even the Denon DL110 HOMC with an published spec output of 1.6 mV. The DL-103 LOMC is .0.3 and the infamous DL 103R LOMC is  approximately the same

I am still mulling over keeping the U-Turn Orbit PlusTT with the Ortofon 2M RED cartridge

There are three (3) types of input adjustments available on the MOON 110LP Phono Pre-amplifier allowing you to configure it for either a moving magnet or moving coil cartridge; Capacitance loading, Resistance loading and Gain level.

Thank you to all members who responded so far. Each has re-educated me about these two types of MC's, and also the dark horse, moving iron design offered by the Sound-Smith company which I considered but only up to the" Otello" model which is listed at $479.

The issue of phono pre-amp gain and pre-amp and amp  gain seems crucial, but so does cartridge/tonearm interface  My current system is a Moon Audio LP -110 phono pre-amp  The MM gain is 40db, and MC gain is 60db. The Moon tech said that the MM gain is high enough for even the Denon DL110 HOMC with an published spec output of 1.6 mV. The DL-103 LOMC is .0.3 and the infamous DL 103R LOMC is  approximately the same. The LOMC DL-103 is actually less expensive than HOMC DL-110.

The rest of my rig is the Conrad Johnson PV14L SE and BAT VK-200 amp; the speakers are the Golden Ear Technology 7's . I am sure how the interface of the amp , pre-amp, LP-110 PP and any LOMC would play out so I need to do a little home work. 

BTW, the Denon DL-110 HOMC weights 4.8 grams. I don't recall the weight of the DL-103 LOMC.   I mentioned this because several of  you  probably saw my thread about TT at $1100 or under. . I am still mulling over keeping the U-Turn Orbit PlusTT with the Ortofon 2M RED cartridge which   has a output of 5.5 mV which sounds better after replacing original motor because of a hum problem. The new motor has reduced 90% of the hum. but there is a residual low-level hum still there, but is not distracting or annoying..

Lastly, with the above setup of electronics and Ortofon cartridge, at step 64 out 99 steps on volume control of the CJ line stage, the sound is very loud. but good.  I am hoping a  better cartridge whether MM or MC will improve the sound, but the tonearm on U-Turn table is not well suited for anything higher than the two Denon MC's  I have indicated.  Any further comments or advice is welcomed    Thanks, SJ
