@billwojo , The single most important factor is to keep the cable as short as possible. I would use a high bandwidth balanced cable like Canare Da206.
I use Sowter transformers which I mounted inside the phono stage with a switch to go back and forth between MM and MC. Doing this depends on how much real estate is available inside the phono stage. The transformers are very small.
