Speakers choice with Octave v80se


I am currently using Octave v80se which have KT150x4 with Super Black Box. (https://octave.de/en/htdocs/verstaerker/v80se.php) My listening area is 10ft x 18ft and  I would like to purchase new speaker. The below are my choices
1. Wilson Audio SabrinaX
2. Avalon PM1
3. Focal Sopra N2
4. Others
Any comments are appreciated

Might want to add Dynaudio to the list. From all accounts they are a very good pairing and Dynaudio distributes Octave in the US I believe. Heard the C60s with the Octave V110 SE I believe and it was very good. Dynaudio have a very different presentation than the Wilson or Focal so all depends on what you like.
Thanks for your comments and I had use Dynaudio C1s with Octave. It was superior sound. I like Jazz and pop with little classical music so I prefer speakers have those characters and  drive well with Ocatve v80se 🎶🎶
I have the same V80 se with a SBB.. it drives my Magico Q3s very well. They are 92db efficient and I have no trouble getting very nice room feeling volume output with the octave. 
Good luck, Jerry
