I want to make clear that the Nenuphar driver and enclosure design has limitations, specific to it. As does any speaker design. For illustration purposes, a large scale multi-driver speaker will deliver aspects related to large scale orchestral music that will fall short with the Nenuphars. On the other hand, the Nenuphars will deliver in areas those speakers fall short in.
I used sophia electric 91-01 monoblock 300b SETs with my Nenuphar Mini’s. Sounded fantastic. Plenty of output. Great detail, texture and very controlled, nuanced bass. I’m actually selling the amps however not because they were lacking in any way. Just that we moved and have some house projects to take care of and I need to sell some gear. I also have some hardly used Takatsuki 300b’s that take everything up a few notches. 
Thanks david & abd for the quick and elaborate replies. I feel now comfortable ordering my 300B amp.
I can see no logical reason why a high quality 300b SET would not be an excellent choice to drive the Nenuphars. @ mga71 congratulations! Are you acquiring a name brand manufacturer or is this a custom built for you amplifier?
