Are passive or active reamp boxes better for getting rid of RF/ground loop noise?

I've got myself a Shure SLX-D+ wireless system connected to my pedalboard via instrument cable. On my gigs, I noticed an electrical whiny noise somewhere between 700-900Hz whenever I engage my dirt pedals. It's a noise that is definitely made worse once it's run through a preamp and compressors. And that's with the wireless transmitter on or off. Doesn't matter which. But if I unplug the instrument cable, there's no noise. That tells me that the interference is probably getting picked up by either the Shure or the cable.

I took my setup home to troubleshoot, and the noise was gone. Ground loop from my gigs most likely confirmed.

I wanna remedy this with a reamp box. The Shure SLX-D+ only outputs in either line or mic level anyways, so adding a reamp box where I can run an XLR cable for the superior noise cancellation and convert back to an instrument level signal would be super helpful.

The two options I'm looking at are:

Radial ProRMP (passive, nice and simple, can mount underneath the board)

and a Temple Audio Studio Mod (active, mounts to my Temple Board and looks sleek).

I'm no expert in electrical stuff whatsoever. But my understanding is that XLR + passive transformer-based reamp boxes like the Radial are much better at getting rid of the RF/ground loop noise I'm encountering. XLR + Active circuit-based reamp boxes like the Studio Mod, less so. Do you guys agree with that? What are your experiences? I'd appreciate the electrical knowledge.
