Very interesting to hear the the Nenuphars have managed to do what most us are skeptical of, the full frequency range reproduction by one driver. It has to bee a special presentation to say the least. Over the years listening and owning many different speakers and drivers I’ve come to realize am silk dome tweeter guy. I can never stand longer periods of listening of other tweeter technology’s. The other day I was able to listen to the new dynaudio confidence 20 and the esotar 3. Frankly I didn’t like the setup at dealer. They had some tube monos based on kt88s and it just couldn’t make it with the bass. Dynaudio have optimized their new models to be a easier load but they still do require some power. I loved the midrange and highs but that was it. I couldn’t detect superiority on much else being away from my critical room. I also heard the new sonus Faber Olympics. They had a warmer and a bit forward sound out of my taste. I much preferred the balanced , neutral and still natural dynaudio. So the Nenuphars seems to me like a great option to an all tube system. Being someone who doesn’t like complex systems and much prefer simplicity and short path to signal, no subwoofer its a must for me. The questions I have would be, how good are the high frequency? Describe if possible. How good is bass on a medium room say 14 x 18 ? Is it deep and able to energize it ? At what volumes? Do they play fast and accurately when demanded? Do they present a neutral and balanced sound or lean towards other spectrums? I appreciate if owners report in with valuable insight of these marvels of modern sound reproduction.
Ricardo,  Your room may be too small for the "10" Nenuphar BECAUSE of the Bass. My room is similar size as yours and I was told to get the Nenuphar Mini's which have the "8".
Good to know and thanks for the report as I value good bass highly in my book. Dynaudios are known for good bass and that is one of my fears in changing speakers.  Other speakers that I heard lately were the Devores O96 and the Magicos A3. Both very good speakers but never made me want to change. I was suspecting the Nenuphars mini would be an excellent choice. Although bass is very important for me I'd be happy with mid 30hz in room response. 
I've been following this thread for some time and think it's interesting and folks are quite helpful and informative. Hope you don't mind a couple of questions:
1) if the Cube driver was designed specifically for amps with low damping factor, why would they work well on the Bakoon 13r and selected other solid-state amps. They must have a significantly higher damping factor than most tube & First Watt, etc. offerings.
2) as anybody heard the Camerton Binom-1 speaker with its unique single driver? Six moons gave it quite the review. Doesn't seem to be any distribution in the US. I also noticed that the driver was recently revised, not sure if it's showing up yet and any products. 
Ricardo,
Given your experience with the Dynaudio, Devore and Magico speakers you have a very solid reference point of high quality competitors.  The Nenuphar Mini is so different philosophically and design I'm very interested in your take on it once you've had the opportunity to hear it.
