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

Charles  However Srajan did have a positive experience using the two Advantages Audio super tweeters with the Nenuphars: https://6moons.com/audioreview_articles/avantages2/
These are omni directional super tweeters for what that's worth.

Hi Steven , I have zero doubt that some listeners will find super tweeters and subwoofer augmentation beneficial with the Nenuphars.  I was just expressing the point that many will find them just fine "au naturel" 😊.

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.
