@stephendunn  Congratulations on the results you have achieved by adding the Playback Designs DAC to your system.

+1 regarding...

The Nenuphars soak up every iota of this upgrade, sounding like new and better speakers in every way.  They keep revealing themselves as true transducers of what goes before them.

I’ve been meaning to add system photos for a long time now. Here are two I just took via my phone.

Click on each photo to get an enlarged image. Second is a close-up of the components. Scott Sheaffer’s left / right signal chassis monos are in the foreground. His left / right power supply chassis monos are immediately behind them in the rack.

[Note: components in the foreground appear much larger than those behind them]

I like the placement of your Nenuphars well into the room. It provides them plenty of room to breathe and perform at their best. The amplifiers have an attractive understated elegance.

@charles1dad Thank you.

@david_ten  Thank you, as well, and what a clean and striking set up you've put together.  As Charles mentions, it looks like your Nens have room to throw an enveloping wall of sound with great depth.  I'm always amazed at the speakers' ability to do this, sound stage like dipole electrostatics, creating a boxless, free floating sound, further enhanced now by my new DAC which renders some recordings--Beck's Morning for instance--in virtual surround sound.  My speakers are closer to the front wall than yours, so I installed half round diffusers which help with image focus but not as much with depth as I was hoping.  Maybe quadratic diffusors help create depth better?  (Or jellyfish?)  Anyway, congrats to you on a great set up.

Speaking of electrostatics, a audiophile friend is bringing over the new Magnepan LRS+ (when he gets them) in a shoot out against the Nens.  He thinks they'll compete despite the 15X difference in price.  Vegas is working up the odds on that right now.  The speakers I would really like to hear against the Nenuphars are the Fleetwood Deville SQ Speakers made by OMA.  Love to hear if anyone has impressions of them vs the Nens.  From what I read they have a lot in common despite being very different designs.
