How can I fix this Phono Stage problem

I have a McIntosh C2200 preamp, Mcintosh MC 402 amp, and VPI Classic turntable with Dynavector 20XH cartridge. I just bought a Canary Audio CA-430 phono stage for this system. The problem is that when I use the CA-430 in the MC setting everything works fine, but when I change the CA-430 to the MM setting I hear a loud buzzzzzzzzz coming from both speakers. I checked all my connection, grounding, and interconnect but the buzzzzzzzz does not go away when in the MM setting. Is there anyone out there with the same problem? Do you have any idea how to fix this problem?
Is not the Dynavector 20XH a moving coil design? I think it is. Leave it on the MC (moving coil) setting, not the (MM moving magnet). I am not sure there is a problem.
The 20XH is a high output moving coil designed for use with a moving magnet phono stage and loaded at 47K ohms. Do not use on the moving coil setting as Dill suggests.

Are you running the Canary into a line input (correct) or phono input (incorrect) of the Mac C2200?

Thank for your reply.
I think the CA-430 is causing a ground-loop. I took off the connection from the TT to the CA-430 and the buzzzz stop. Then then I tried a cheater plug on the CA-430 but that still did not stop the buzzzzz. I have an old Mcintosh C39 preamp in another system and when I plug in the TT and the CA-430 into that system everything worked fine, including the MM setting on the CA-430. But when I return to my primary system with the C2200 I am getting the buzzzzz once more. How can I get rid of the groung-loop. I know that some people don't recommend using cheeter plug, but so far that has not work to get rid of the buzzzzzzzz from the system.

I am running the Canary CA-430 into the C2200 phono/Aux input. I have used that input with several phonostages including Modwright, Graham Slee and SAP. But I did not get any ground loop problem like now. And I have always use the Dynavector 20XH high output MC cartridge with the phonostage set in the MM setting for this cartridge. Are you suggesting that I use one of the other line input (tape, CD, DVD,etc.) instead of the Phono/Aux on the C2200 preamp?
Yes, input the Canary into another line input other than the phono/aux and see if that ends the buzz.

I think I found the solution to the problem.
I took off the interconnect from the TT to the Canary and tried several of my other cables and the buzzzzz was still there. So for some reason I dig into my archive and pulled out a 20 year old Radio Shack interconnect. I was shocked!!!
The buzzzzzzing stopped. I tried another Radio Shack interconnect and it also worked. I went back to my expensive interconnects to verify, and the buzzzzzing was there again. I have interconnects costing up to $450/pair, and to see a $5.00 twenty year old cable solve the problem was unbelievable. I measured the resistance of the Radio Shack cable and it was 2 ohms. I measured the other cables and each was about 10 ohms on average. It seems like the Canary does not like the high impedance cables. I tried six pairs of my premium cables, and two cheap cables did the trick. I think the problem lies within the Canary because I used several other phonostages and I did not get any buzzzzzzz. Now I to figure out which premium cables have the lowest impedance that will match up with the Canary. Do you have any ideas? or did I miss out anything? or have you come across low/high impedance cables?
Some high end cables have some weird grounding setups. It could be that you have run afoul of one of these, wherein the way that the Canary is grounded is different enough that the cable is not compatible.

A 10 ohm resistance is rather high though. Is that in the shield connection??

FWIW, there are a good number of LOMC cartridges that are less than 10 ohms. A resistance like that could knock the output of such a cartridge down by half or more! This may not be the best cable for phono use...
There could be a number of issues with the particular cable, apart from the difference in resistance that you measured. As others have noted, cables are grounded differently. You could try flipping the expensive cables around (many have directional arrows because the shield is grounded on one side only).

It may also be the case that the cable is not shielded. I once had a problem with buzzing with Kimber cables that was cured by getting another Kimber cable that was supposedly identical, but for the fact that the one that cured the problem was shielded. When the two cables were tried in a setup where noise was not a problem, the unshield cable actually sounded better, so there may be a tradeoff using shielded cable, but one that is certainly worth making if noise is an issue.
