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

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 
I have the V70SE with Tyler Acoustics MM5's and it sounds really good to me.
I would also add Duevel to the speaker mix. My Venus work great with the V70SE integrated. The Bella Luna would be quite wonderful as well.

Probably quite a few possibilities, it is more up to your ears and experiences/preferences.
