Tubes or stick with S/S

I’m Single-Ended Triode. I also like mechanical watches. I have a SS amp down below for the family system. Like a mechanical watch - it wins before turning it on. I am enjoying my wife coming up to my cave to hear the music she can’t hear on the SS. To be fair, I spent 10X as much on it. Just like my watches.

Edit - add:
@15W/channel - I am near field, but never go above 30% dial.  I have run Martin Logan 35XT and not Watkins gen four (wow).  No issues with power.  Pushing ribbon, I understand I need more power.  So not pushing ribbon.  

     As a lifelong user of class AB and recently class D  ss amplification mainly out of necessity with my multiple succession of inefficient Magnepan speakers, I'd recommend going for the Primaluna and tubes or even a SET, especially with your highly efficient Klipsch Cornwall IIIs. You'd still have the option of switching back to your ss McIntosh during the summer or whenever you desired.
     I owned a pair of the original very efficient Klipsch Heresy speakers in college 40 yrs ago and still regret not even contemplating driving them with tube amplification.  
     I didn't even realize until years later how spectacularly beautiful music can sound with good tube amps driving well matched speakers.  
       Ever since listening to my 1st high quality system about 35 yrs ago, I've considered tubes as having a certain mystique and, please excuse the oxymoron, a certain coolness.  I've since experienced several friend's tubed systems, always impressed with the sound performance but also with the tubes glowing in the darkness that, imho, just adds to the enjoyment of listening to good music well reproduced.

The Cornwall III’s are 102db, you don’t need much in the way of watts, I would go the new 25w "Class-A" Schiit Aegir solid state $799

You can trial it for 15 days!!

Note that Dennis Had's amps are almost unobtainium and I found mine, a late 2016 sep ("p" for pentode), simply from a lucky Ebay score. You can buy the mono blocks from Moon Audio but they're pricey although likely worth it. My little Firebottle version is 12wpc or something (depending on the tubes you stick in it) and drives Klipsch Herersy IIIs with gusto. A Steampunk tone monster that has astonished me from day one. I'm also a mechanical watch freak...latest faves are an Oris Divers '65 with the distorted deco-ish numbers, and a Ball Trainmaster Power Reserve (tritium glow tubes...who doesn't like those?)...another hobby that exactly zero of my friends care about.

See the link posted above. Brand new 300B FireBottle SET for $2K, plus shipping. Looks like a nice piece. Audio Nirvana also has a 300B SET for $1595. Haven't heard either.
