Congrats Stephen.  That's great to hear.  And I know it's not a diy-heavy crowd, but if people find a SIT-2 and want to convert it into a SIT-1, I believe there are only two core differences... separate power supplies for the monos, and the adjustable aspect of the 2nd harmonic on the SIT-1s.  In the end, a SIT2 with one channel broken out into its own chassis and with its own power supply will probably get you most of the way there.  Anyone who's built a DIY first watt amp could easily make the conversion.  I've found a huge impact of adding a separate power supply for each channel.  I'll never go back to a stereo amp again.

Please keep us updated on the journey Stephen.

Steve,

It has been fun following your  listening impressions and reporting as your system has evolved. After all isn't this the entire point ?  Discovering  ways to improve our music listening experiences. and engagement. It really makes me  happy  when someone  gets ever closer in connecting with their music be it streaming or a collection of recordings.

...the SIT-1 poked through the clouds to a performance peak I have not experienced with the Nenuphars--or any other speaker for that matter.

Stephen, first let me say how much I love your writing style and reading your prose. It flows so easily and expresses so much. 

Second, congratulations on acquiring the First Watt SIT-1 monos and their contribution to your system and the resulting peak connection to it via the Nenuphars.
Thanks, David.  The information that you and others have provided in your thread has gone a long way to helping me better understand and optimize these wonderful speakers.

Of late, I've been auditioning cables.  I've been comparing Synergistic Foundation cables against their higher-priced stable mates Atmosphere X and against the hodge podge of my existing cables (Teresonic, Dueland and Teo Audio GC).  I started with the Foundation replacing my Dueland speaker cables and was startled by how much better they were.  In fact, it prompted one of those classic moments where my wife came in and said, "You just changed something."  The Dueland cables sounded vintage, rolling off highs and smoothing transients, very pleasant, but the Nenuphars don't need that tonic.  The Foundation cables brought out their best, even to a higher degree I thought than the Atmosphere X Excite speaker cables at more than four times the price.  Interestingly the X Excite cables exhibited some of the Dueland characteristics, being smoother and mellower.  (An added plus to the Foundation speaker cables, for those with white Nenuphars like myself, is they come in white!)

The Foundation speaker cables made the most impactful difference, but the interconnects reinforced their benefits in audible ways.  I'm now auditioning the Atmosphere X USB cable against the Atmosphere X Reference USB. 

The homebound joys of landscaping and falling into the Nenuphar's musical spell are helping to keep me sane in these harrowing times.
