When I show up to set up my show on a stage, there’s normally monitors at the front of the stage. If I’m doing a solo show (not in a show with multiple performers), I will ask the sound tech to move the monitors. I think it’s important for the audience to see my whole body, but more than that, I do a couple of low things and with monitors, that stuff is invisible to the audience.
Recently on a travel day while I was looking for lunch in a town I stumbled up on a festival. One of the acts on their stage was an Irish Stepdance group.

Look at the picture above, you really can’t see their feet! I understand that’s unfortunate placement of the gray power box in the middle, but there’s no reason that the monitors couldn’t be moved to the sides of the stage and turned so they face the middle. That would not affect the dancer’s ability to hear the music.
In a magic show, we don’t normally need monitors like a band does, so don’t let the sound tech set up your show like a band! It’s OK to ask the sound tech to move monitors, they’re easy to move and it’s not a big deal.
Here’s a post I wrote almost a year ago with some good comparison pictures:

Now be assertive and visually clean up your stage!
