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

I did ask Jon why he didn't use tube amps. He smiled and said he was good friends with Nelson Pass....

Jon also used Pass/FirstWatt amps and preamps back in his Lowther America days.

I just hooked up a pair of Sophia Electric 91-01 mono blocks to my Nenuphar minis. I really haven’t had time to listen much at all so too early to assess but in the brief time listening I am liking what I’m hearing. The reason I went for these amps is the owner was including an almost new pair of Takatsuki 300b’s. I started listening with a pair of included Shuguang black treasure series 300b’s. They were fine but a little lean sounding. I just put in the takatsuki’s and wow, huge difference. Tone is richer and soundstage wider and deeper. Everything just got bigger and more alive sounding. When I get more time with this combo I’ll report back. I’m also moving and will have a much better listening space but that won’t be until mid September. 
I’m also wondering if anyone is using a sub with their Nenuphars? I’m using a pair of REL T5i’s. I’ve been really impressed by these little subs. I don’t have them turned up much but they really blend well. 

@rwpollock  Robert, good point and on the money. Srajan Ebaen's initial review also shined a bright light on the SIT amps, and then Bakoon.

As Charles mentions, it is perhaps incongruous that few on this thread have followed the designer / builder's lead with 45 and 2A3 pairings. 

I received very strong pushback on going the 2A3 route, from many, since they were highly skeptical of the ability of 3.5 watts to properly drive a 92dB / 6 Ohm rated speaker. 

Charles was steadfast on the pairing and I'm so glad I followed his advice. Once again: Thank You Charles.

@abd1, 
My then new (2009) Frankenstein MK II came standard with  EH 300b tubes and they were solid performers.  I soon upgraded to the Shuguang black Treasure 300b which was an immediate and obvious improvement.  I later moved on to the Takatsuki and like you said, "WOW"!! Better in every conceivable way. 

David I know as high as your expectations were, the Found Music 2A3 SET and Nenuphar pairing has exceeded them. 3.5 watts of supreme quality and implementation. 

 Certainly specific situations dictate choices but too often more power (Watt quantity) is the default recommendation when in fact  watt quality is the answer.  David you were generously rewarded by sticking with your well reasoned convictions.

A strong recommendation for using headphones / earphones / IEMs for the video playback.

The comparisons between audio output via my laptop speakers vs. the 3.5mm laptop analog out vs. the Audioquest Dragonfly Red DAC/Pre/Headamp to Sony WH-1000XM4 headphones and Noble Audio 4C IEMs are (obviously) vastly different.

I'll try playback via USB Audio Pro / eXtream Software Development (The Netherlands) next.

Sony leash is stock. Custom Linum / Estron (Denmark) leash for the Noble 4C.

I'm not in my audio home base, for the time being, and cannot access my primary headphone systems.
