Hi Shug,
I run RCA cables between my D2 and MCA50, but you might as well run balanced.
As with all audio cable choices, there is no silver bullet, it just comes down to using cables that you are comfortable with and that you like.
A lot of people seem to like Shunyata, Analysis plus, Audience and Cardas cables. For much cheaper, I like both signal cable and Blue Jeans cable, and use them throughout in my HT setup.
