VAC Signature 2a Preamp Question

Before you say, "Dude, there's already a thread posted about this question!" Well, forgive me, I could not find it. This is an inquiry for Signature 2a owners who have the built-in MC/MM phono stage: When the selector is on #6, which is the turntable, I get a background hum and some of what is probably tube rush, and it's especially audible with no music playing with the volume up. When I switch to the DAC setting, with the same volume setting, everything is dead quiet. Do I have a problem or is this normal?

Your feedback is welcome and appreciated,

Did you connect the ground wire from your interconnect running from the tonearm to the preamp chassis?

Adding to Dweller's comment, is the control section of the preamp sitting on top of or close to the power supply?

You're right, it really does look cool, that's one of the things I like about my Phi 200 as well. I know it's not as aesthetically pleasing, but could you move one of the amps down off the rack and put it on a lower platform in front of the rack, then put the power supply on the bottom shelf? Otherwise, maybe get a high output cartridge? :^)
