I heard the Nenuphar Basis with First Watt amps and really liked what I heard, much more so than the Nenuphar without the woofers.  I do wish to hear them with a warmer tube amp, like a 6L6 or KT 66 amp.  The are efficient enough for a single ended triode to at least be in the contest.

@david_ten  drives his Nenuphars to magnificent results paired with 2A3 SET mono blocks. Granted they're uber quality SET.

Just saw some photos of the show. It looks the Cube’s were paired with Nelson’s one off 2000 JFETS 20 watts amp. Scroll down to see some pictures of the amp...pretty unique looking.
