Hi everyone, I've been following this thread closely for a while now.  So much interesting information. My curiosity about the Nenuphars has been though to control after reading all experiences here.  I want to spend some quality time listening and experimenting with them.  I've been a fan of dynamic speakers for a long time and keep hearing about efficient full range and their optimal matching with tubes wich I consider essential for my taste also. My last speakers have been Dynaudio and for most of the time it's been a great experience and a joy to live with. They have been doing all the good things for the longest time now but the Cubes just keeps popping up in my dreams.  My system is pretty basic and straightforward, it  consists of a HD plex fanless computer withthe goodies, a lampizator big 7 dac and a LTA 40i integrated amp. Although the system isn't totaly focused on the powerful side it can handle a good size speaker no problem but I can only imagine going the eficient and simple path root.  Though decisions.  .
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.
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.
