Cube Audio Nenuphar Single Driver Speaker (10 inch) TQWT Enclosure

Thanks, yup I realized non of my amps maybe the "best" match, but will report back on if I’m lucky :)

The suck thing is I sold my SIT3, preferring the BHK250 over it for my Klipsch Cornwall III.  So hoping my preferences will win at the end of the day

David both reviewers basically just confirm what the Cube Audio owner/designer so openly shares with everyone willing to listen to him. That extraordinary driver he painstakingly developed simply doesn’t need a NFB amplifier with gratuitous DF levels (low output impedance) to control it as many other speakers do benefit from. Frankly I am surprised that the PS Audio BHK amplifier has such a high DF (>350) that’s a lot of NFB being utilized in that circuit design.

Nevertheless wouldn’t it be something if both of khragon’s amplifiers sound terrific driving the Nenuphar? This speaker fascinates me. David I can easily understand why it sounds superb with your 2A3 mono blocks or the LTA Ultralinear amplifier mentioned earlier above.

The BHK 250 has >150 DF, where as the mono block BHK 300 is >350.

@david_ten 

did you move away from the Tekton and T+A system?

The Klipsch is a high sensitivity speaker yet may possibly  benefit from more power due to crossover design and big woofer control. The crossoverless,   very easy to drive load Nenuphar is a different animal. S.I.T. 3 amplifier and Nenuphar is considered to be a splendid pairing. As they say, "horses for coures".
