I'm shocked an inconclusive listening test... Throw out the outlier (who picked one) and move on.
Amplifiers operated in their linear range (i.e. properly sized and rated for the application) should sound indistinguishable from each other. QED
Not to mention the elephant in the room, loudspeakers (even Danley's) are not as linear as modern power amplifiers.

Yeah there is no way I would choose one over the other based on the listening test we did.
I "think" the only reason some chose B-was because when the went to B-we heard a "change" but when we went back to A- we did not hear a change. I can't explain that-except maybe the way the switch was acting.
Agreed that loudspeakers are without a doubt the worst piece of gear in the whole signal chain-BY FAR.
But we did use the same loudspeaker for the tests-so the only variable was the amp and yes the gains were matched by measurement.
We just did it as a test to see IF we could tell a difference.
No we did not run the amps full tilt-as that would get into non linear operation-and then all sorts of things change.
