ZYX Airy 3 Best SUT

I want to run an Airy 3 via a SUT into my Audible Illusions 3A MM input. The gain on the phone stage is 28db & the line stage is 30db. I am looking at upgrading my preamp further down the track so this is only a temporary set up, I don't want to spend big money only around $1,000. According to the specs the output on the Airy is 2.4mv & the Recommended Load Impedance is >100 ohms.
Could I please have some recommendations?
Thanks in advance.
