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

@cal3713   Yes and remarkably consistent findings.

@stephendunn  I looked as well. Unfortunately, not. His audio rack does offer clues. : )

I also noticed the absence of identifying associated amplifiers and found that odd given the unique matching considerations for the Nenuphars.  Still overall a good review as I believe the reviewer captured the essence of these exceptionally  special speakers. 

I feel that Srajan Ebaen's 6 Moons review of the Cube Audio Nenuphar is the most compehensive.
1 In depth technical description with ample commentary from the designer/builder. 
2 Effective use of metaphors and analogies (IMHO, I know some don't like his verbose writing style) in his very  detailed subjective listening impressions. 
3 Taking the the time to use multiple/different amplifiers paired with the Nenuphars and then clearly describing each separate pairing. 
4. Comparing the sonic character of the Nenuphars with other familiar speakers he holds  in  high regard in his listening room and review audio system.

@charles1dad  I have emailed Matej requesting information on the amplifier(s) used, etc. I'll post, should I hear from him.

Since we are all wondering about the amps, here is what was communicated in the review:

"Cube Audio Nenuphar was designed from the ground up to provide the best possible matching partner for a low power Class A (minimum 3 watts) tube-based and solid-state amplifiers. For tube amplifiers, Cube Audio recommends such designs based on 2A3, Px4, 45 tubes. I can see many of SET connoisseurs and afficionados' eyes illuminating."

@stephendunn  This review may be of interest to you as Srajan Ebaen mentions going forward with the Linlai 2A3 for his VR linestage.

David,
Thanks for the link posting. Srajan Ebaen really loves the Elrog 300b and as a former owner I understand why. It’s interesting that an upstart 2A3 impressed Srajan to such a degree. This Lanlai 2A3 is roughly 1/3 The price of the esteemed Elrog..
