Best option for SACD and Wadia 151?

I am sort of new to this pure digital stuff. I just built this setup:
B&W 685's
Wadia 151
Peachtree X-1 bridge
iMac running Audirvana.

So what is the best way to listen to an SACD player on my Wadia 151?
Would a analog to digital converter be my best bet since digital out doesn't work on a SACD player unless its HDMI or 7.1? Any models in particular?
Any comments would be appreciated!
