So you think Cord Mojo using headphone option ?
Thats what I use to drive my AJ.

I don’t know what a Cord Mojo has for a power supply. You will need a source that has about +/-15v rails and can drive a lower impedance load. Most “headphone amps” will handle the current needs but not all can swing +/12.5v.

I have some idea of what you are projecting, but i personally don't abide by it. I posit G.B. Shaw:
The reasonable man adapts himself to the world: the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
AFAIK Chord has been an advocate of switchers since they started (decades ago?)

They started using a supercapacitor array, as of late... with great result. I think this is the future for all digital HiFi sources... (not including a high power amplification).
The Meanwell SMPS's I used inside the ACA amps are absolutely phenomenal. I think once I loaded them with close to 2A (on a test bench), their voltage drop was only a few 10ths of a volt... insanely good. Also, dead quiet AND they very providing nice, low impedance over the entire audio range. I am thinking of using the SMPS's inside my Aleph J as an experiment.

Progress is so overrated.
Look where we are now.

Is there a "quality difference" between P and N channel VFETs like there seems to be if is was MOSFETs where N-channel seems to perform better than P-channel?
Well, I'd be happy to be called a Renaissance man.
Puts me in the same bracket as Leonardo Da Vinci, Nicolaus Copernicus, Johannes Kepler, Erasmus, Dante, Botticelli, Michelangelo and a plead of others.
What's to complain about?

Pa said two iterations being of same performances
not 100% sure about, I think sole difference could be phase of 2nd
so irrelevant, just flip the phase of speakers

with these exact names, I thing Rudjer Boskovic must be included, even in short list 🙂
Take this as evidence of nothing... but we DO prefer 6L6's Vfet (still here! ;-) with speaker jacks flipped! Seemed to open up the sound stage IMO... we all agreed it was not an insignificant change.
Agreed.
When it comes to how you attach speakers, try both ways, if you prefer one, that’s the best way to listen. Neither is ‘right’ or ‘wrong.’
Some amps the effect is more noticeable than others.

And it could change from recording to recording.
