If you’re ever able to hear both the Magico A3 and Nenuphar (Each respectively driven by an appropriately matched amplifier) I would be quite interested in your listening impressions. Those two speakers are so different and at near opposite ends of the spectrum in regard to their design. I imagine that they sound very different from one another.

I am also eager to hear about this comparison. Apart from different design, their amplification requirement is also very different.
I find my 94db/1w/1m, 8ohm speakers somewhat limiting in terms of amplification.  Plenty of people do, but I don't think I'll ever move beyond the 25W/channel I currently use.  Watts may be cheap, but if I'm dumping funds into amplification, I'd still rather dump them into fewer watts than more of them. 

The amps also tend to get so complicated the more power they're managing... just look at Nelson Pass' First Watt line to see how alluring the low power designs can be.  He has the capacity to build some of the best reviewed high wattage amps available and still spends a huge amount of time (perhaps the majority?) playing with low power designs.  
Cal,
Yes, Nelson Pass has thoroughly demonstrated his acumen of designing and building excellent amplifiers across a very wide power spectrum. 
He's enjoyed remarkable success with his Pass Labs amplifiers.  Yet I find his explorations via the First Watt line of amplifiers so intriguing.  He obviously has a deep passion for these special amplifiers given the multiple models/versions He has developed (And continues to do so) over the years. Every one of them is uniquely different from their siblings.

Thanks guys! I already had a casual listen to the A3 driven by Hegel 390 streaming Tidal off internal dac. Playing Norah Jones Come Away with Me album. What stood out was how wonderfully coherent the sound was. Slightly warmish with lots of air. Great focus. Norah's head was in between the speakers. The American distributor says there is a owner near me so when his Reno's on his home are done he will try to arrange a demo for me of the Cube Audio. Magico at first listen lacks tonal richness on say a piano. But have to listen more.
@charles1dad  What's crazy is that Nelson not only makes the commercial First Watt amps, but also releases (for free) additional FW-like designs for the diy community.  I was just reading about a single-ended 8W SIT amp that he's going to release kits for soon:  https://www.diyaudio.com/forums/pass-labs/357517-simple-se-sit-amp.html

I like this quote from him regarding the design:  "I tried to make it more complicated and obscure, but it's just not in me."  

Just more evidence in favor of the combination of sensitive speakers and low wattage amplifiers in my book.
