How can I fix this Phono Stage problem

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?
