@david_ten Thanks for posting!  Interesting that he comes to a different conclusion about preferring the 10" driver over the 8" (vs. Jon @ Refined Audio and some of the posters here).
I would be pairing the Nenuphar with a Class A Clayton Audio S40  SS amp with current upgrades. The Audiophile’s Wife approves the aesthetics of the Nenuphar.  Most important!

Although I think I'm the newest Nenuphar owner on the block--just at 2 weeks--I'll chime in with my answer to your question regarding the speakers resolution making "below average sounding recordings sound less enjoyable or possibly bad?"

My answer, yes and no.  Yes, their resolution reveals more about the recording space/method than any speaker I've owned.  But not in a tipped up, etchy way.  It's just a natural openness that brings me deeper into the recording.  But that resolution doesn't necessarily make below average recordings sound worse.  In most cases it made them more interesting, because at the same time the speakers are revealing the recordings quirks it's also revealing the strength (or weakness) of the music.  For instance, a lot of Billie Holiday's work is poorly recorded.  The speaker doesn't shy away from that but it also brings such tonality and nuance to her voice that you quickly forget the recording quality and are absorbed by what you've never heard before in her singing.  

On decently to well recorded material the Nenuphars bring you into the recording space like no other.  Listening to well recorded live albums can cause a virtual reality experience.  On the Marian McPartland album 85 Candles (Live in New York) you not only feel like you're in the audience at Birland but you can hear the patrons clapping on either side of your listening chair!  How's that for sound staging!

BTW, I just purchased your Acoustic BBQ Dueland 12ga IC for my system.  Looking forward to the audition.

And, yes, thanks David for pointing out Srajan's latest (which is now finished).  I now have the term for what I'm hearing from the Nenuphars driven by the SIT-3: Tuscan sunshine!

Hi Steve,

Your Billie Holiday example is an excellent one. As I improved my audio system over the years I became more aware of recording flaws yet this was overpowered by the increased naturalness of tone/timbre nuance just as you observed . This heightened awareness was particularly noticed when I began using my 300b SET amplifiers. The ’naturalness/realism’ factor went up a level without question. I can certainly see how the Nenuphars could have the same effect (if not even more so). Bottom line, you aren’t distracted by recording imperfections.

Bill what are your Clayton amp’s specs in regard to

Damping Factor

Output impedance

Utilization of NFB?

If you read the initial 6 Moons review of the Nenuphar you'll find considerable discussion on these parameters and their effect on the speaker’s performance.
