Odyssey Kismet Reference or Ascend Acoustics Tower with RAAL Ribbon Tweeter

Ready to upgrade my speakers from Ascend Acoustics Sierra 2 with RAAL’s to either the Ascend Towers or Odyssey Audio Kismet References. I’ll be running them with Odyssey Khartago Extreme SE and Candela preamp. Has anyone listened to both speakers, and if so, what are your impressions. I also appreciate any critique you have if you've listened to either speaker.
I have the reference monitors. Of the three pairs of speakers I have now, these are the ones I am not selling. Smooth,nice bass and punch. Non fatguing all day long. I have never heard the Ascend. Hope this helps.
