Speaker match for Simaudio W8/P8

I know speakers are very dependent on personal taste, but I'm looking to upgrade my speakers and would appreciate some advice from fellow agoners. My amp/preamp is the Simaudio W8/P8 (250W ss stereo amp). Current speakers are Dali Mentor 8s. I'm open to buying new or used, 15K or so price range. Considering Dali euphonia MS4/5, Sonus Faber Elipsa, Von Schweikert VR5 anniversary, Wilson Sophia 3/Sasha (a bit of a reach), Dynaudio Confidence C4. (Dynaudio seems to be paired with Sim at audio shows) or Eggleston Andra3
Room is about 22x18 with listening area 2/3rd of space, source currently is esoteric DV60. Please let me know what you guys think, and any other speakers I should consider. Thanks
