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.
