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.
I'm running my Nenuphar with the Apherion dual AMT Supertweeter.  I found the addition of the supertweeter to enhance the listening experience,  especially with sound staging and the subtle but imo important treble decays.  I went back and reread some of the reviews and this was mentioned.  I had mine crossover at 12khz and -2dB.

I also run the Nenuphar with a pair of Rel S510 subs.  I like them but could easily live without. I had crossover set at 20hz and volume up at 4 clicks.

The Nenuphar provides a strong foundation for owner to customize the sonic spices to their liking, a sprinkle of bass here and treble there provides different experience and I enjoy the journey and customization depends on my mood.  At times I do turn off all effects to enjoy the Nenuphar sans crossover, and love that I have that option.
khragon Thanks for posting about your use of the Apherion supertweeter. I’m curious about how you have them installed. If they sit on top of the speaker, the rake would make them point far over the listener’s head at the front. My understanding is supertweeters are highly directional. Or do you have them propped so they fire straight ahead? Maybe the Apherion drivers provide more dispersion. Insights into installation would be appreciated.
Here are some photos of the setup:https://goo.gl/photos/rinLZWzHoBvCizNLA
I have the supertweeter on the same plane as the speaker, both slightly toed in into the listening position.
khragon Impressive set up!  Thanks for sending photos.  Rare to see the Nens with the grills.  Don't think mine even came with.  More importantly I see how you've installed the Apherions (and subs) and I'm thinking I will try the supertweeters given they have an in-home audition period.  I have had speakers in the past that benefited from forward only firing super tweeters, but think the dual design is the way to go, adding depth and probably air to soundstage.  I am in a relatively small room and although width of ss does not seemed cramped, depth does. With the SIT-2s in place, along with the help at either end of the spectrum, I bet your Nens sing.
