Has anyone compared Zu Omen with Spatial Hologram M4?


I just posted a couple days ago about upgrading my Zu Omens (that I am quite happy with). When researching here and other places I came across the Spatial Hologram M4s. They obviously take quite a different approach. Has anyone compared them or heard both of them?
I would love to hear your impression. 
I am trying to decide if I should upgrade my Omen speakers or try out something different>

Thank you.

I have no idea but I might get a pair next year as a second pair of speakers. I reached out to Clayton a couple of years ago and he was very responsive. The price is right and I love the open baffle design.
