Looking for speaker to match with pass lab aleph3

I presently own the pass lab aleph 3 bought them recently after reading Stereophile's review. Its a wonderful amp but it don't have enough power to drive my current speaker (Sonus Faber Concertino). I'm looking for a similar sound, listen to mostly vocal jazz. I'm now particularly interested In B&W Nautilus 805 (88dB/W/m) and Zingali Overture 1Bs (89dB/W/m) or perhaps any other models that are better match, that you would recommend. I would greatly appreciate responses from people especially from those who may have heard them first hand or someone with an experienced opinion.

Thanks in advance for responding,
