Speakers for First Watt SIT-1 amp

Id vote for a Voxativ ...perhaps supplemented with  a REL sub.  They have a FIT model now with a 5" driver ... perfect for mid size rooms.  $5700 with the AF2.6 driver. 
FYI, I owned a FirstWatt F7 and my Voxativ sounded lifeless with it.  I almost opted to try the SIT3 but the reviews were meh.

ggking7, I can comment on my own experience with single driver speakers vs multiple. I listened to Lowther in fideleo cabinets for about 17 years exclusively. They are wonderful speakers. Great imaging, very dynamic etc. I have to tell you I don't miss them after trying the Tekton open baffle speakers. Again, it's not that the Lowther's were by any means bad, but the Tekton's took the system up a couple notches in regard to just about everything. The place the Lowthers better them by a small margin, is width of the sound stage. The Tekton however give me more detail (without anything close to analytical), speed, stage depth, & instrument presence.      

charles1dad, thank you for the recap. I had missed that Cube Audio does single-driver speakers. Wow the 6moons review of the Nenuphar is exciting, especially since I already have the SIT-1. It looks like the Magus and Bliss C each go for around half of the Nenuphar’s price. I think I’m between Cube and Voxativ at this point. My impression is that Cube is a better value. Does anyone have a handle on how the speakers from these outfits differ as far as performance?

I should also mention that I'm using a Rythmik sub but it sounds like it wouldn't be needed with the Nenuphar.

Hello ggking7,
If you really decipher Srajan's glowing praise it would suggest that he's quite possibly more unimpressed by the Nenuphar than the voxativ models he is very familiar with. Send him an email for his thoughts  on this. He's actually pretty responsive to inquiries from readers of his site. .  In your case  particularly as he owns your amplifier (for several years) and holds it in the highest regard. He seems genuinely moved by the sound quality of the Cube Nenuphar and this would explain the very rare award he bestowed on it.

Ggking7, 
You mentioned the Cube Magus (8 inch driver) this speaker received the coveted Blue Moon award last year. So you know how impressed he was with its performance. It appears that the Nenuphar with the newly developed 10 inch driver and very powerful motor/magnet unit (and special cabinet) is clearly superior (to his ears) and explains the justifiably higher cost. This seems to be a very  upper echelon speaker.
