Nagra VPS MM configuration

Has anyone configured their MM input on the VPS? I have a Kondo IO-m and the Kondo SUT and am having a hard time setting it up right. There's a "haze" around the music (vocal in particular) that sounds like distortion. Not sure if I'm configuring it right and I'm certain I don't have the right load. The cartridge directly into the MC (no SUT in path) sounds great.

Thanks in advance.
