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,

I have an Aleph 4 (100w/ch). I realize that its more power, but when I had Revel Gems, I didn't need anywhere near that much, making me think the Gems would be fine with the Apleh 3. The Gems are a very detailed neutral speaker.
I had the Aleph 3 with both Meadowlark Kestrels and Dunlavy SC4s. That is a great amp, I upgraded to the Aleph 2s, at 100 watts it is not much more power than the 3. I actually thought the 3 sounded better in most ways than the 2s, except in the bass. I could get pretty loud with the Dunlavys and the Meadowlarks. If you aren't looking to spend a lot of money the Meadowlarks are a great speaker to choose.
Quads (57 and 63 variants) work well with the Pass Aleph 3 and 5, in my experience.
I also have an Aleph 3 which I beleve to be a superb amp especially for Jazz. I am using them with ProAc 2.5s with excellent results. My room is about 12 x 15 and play them at reasonable levels. I also have a pair of 1sc and they also work extremely well with the Aleph 3. Remember this amp does need about 45 minutes to fully warm up and sound its best.
Check out Silverline speakers. I am using the Aleph 3 with a pair of Sonatina I's with great results. Make sure you invest in a good after market power cord, like NBS. Gjrad is correct, 45 min. to an hour warm up for the best results.
