There is a clear and accurate technical reason. Musically pleasing to
our ears is the difference between an audio signal containing 2nd or
even order harmonics vs. a signal containing 3rd or odd order harmonics.
Even harmonics (i.e., second order harmonics) are considered to sound
fat and warm, although they can be muddy and soft sounding as well. Odd
harmonics (i.e., third order harmonics) are considered harsher and
edgier sounding. A pure square wave gives only odd harmonics. A pure
sawtooth wave gives both even and odd harmonics. A pure sine wave has
no harmonics other than the fundamental.
And now you know the rest of the story.

I recently sold my S-Line that had a 75S3C receiver in it and I’ve owned two
K3’s and now a KX3 and KX2.
I gotta admit that the tube audio was much more pleasant to listen to as
compared to the solid state rigs.
Can’t exactly say what the differences are but the tube audio sounded much
“fuller and rounder” that the solid state gear.
Don’t know if that poor description helps, but there it is.
