New Spatial Audio M4 Ultra

It looks like the M4 Ultra replaced the M4 Sapphire and the M3 Sapphire seems to be on hold pending tweeter availability or retooling with a different tweeter. The new M4 ultra is so new I doubt any have been shipped yet. 

Clayton has said the silk dome tweeter will cross at 800 hz on the Ultra vs the 576 hz cross on the Sapphire. 

Just heard Spatial speakers at NYC show with Linear Tube Audio electronics and I thought were one of the best sounds I heard by far.  Extremely dynamic and, uh, spatial sounding.  Big time on my radar as I already have an MZ2 preamp. 

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.
