New Spatial Audio M4 Ultra

I have the Spatial Audio X5s and they are very dynamic, open sounding and have superb bass.  I've always been a box speaker owner but after purchasing the x5s a few years ago don't see myself ever going back to box speakers.  The sound is so much more open and live sounding.  This is of course just my opinion.

Yes the M4s are so new I'm sure no one has them yet.

Thanks for the responses. I ordered a pair, 4-6 weeks lead time so I’ll update this thread if anyone is interested in impressions (after break in) 

Definitely interested. 

Interested as well. 

Discussions about this on Audio Circle. It looks like the tweeter for the M3 is no longer available to the M4 Ultra has a different tweeter and is a smaller speaker in stature (about 1/2 foot). The X series (I also have the X5s) are still available with the X4 Ultra having a passive woofer whereas the X5 and X3 having the woofer driven by a class D amp. I also found a used LTA Z40+ integrated amp and they go together very nicely.
