Is the appeal to euphonic distortion learned?


Hi everyone,

I have been thinking a little bit about the idea of euphonic distortion. The idea that we can make an amplifier or preamplifier sound better by not being so absolutely true to the input. The common story is that by adding 2nd order harmonics the music sounds more pleasant to more people. Certainly Pass has written a great deal, and with more nuance and detail about this and makes no bones about his desire to make a good sounding, rather than well measuring product.

Lets keep this simple description of euphonic distortion for the sake of argument, or we’ll devolve into a definition game.

I’m wondering whether it is possible that this is in large part learned? For instance, if I grew up with non-euphonic amps and then was exposed to an amp with high amounts of 2nd order distortion would I like it? Is the appeal here one which you have to have learned to like? Like black coffee through a French press?

And this discussion is of course in line with my thoughts about the ear/brain learning process. That there are no absolute’s in music reproduction because we keep re-training our ears. We keep adjusting what we listen to and ultimately at some point have to decide whether the discrimination between gear makes us happier or not. (Go ahead writers, steal this topic and don't mention me again, I know who you are).

I was absolutely transfixed by the sound coming out of affordable KLH acoustic suspension speakers before I knew they were being driven  by McIntosh tubes, and I didn't  know what McIntosh was.  I always wondered whether it was the tubes/2nd order distortion or the sheer power and control the McIntosh was able to deliver. It was my first encounter with tubes. Never bought McIntosh but now own VAC and love to listen through it.  Seems more fleshy.
This is why I tried to define "euphonic" very narrowly.  It is super hard to talk about why we like colorful gear.

For instance, I love the Conrad Johnson Premiere 12.  They are the ne plus ultra of amplifiers in my mind.  Neutral?  Hardly! But I can't really explain why.  Those are just very colorful seductive amps.

I was wondering about distortion specifically.
We all had parents of a variety of cooking skills and tastes, but that's what we learn as homey, and no restaurant can match it.

If I went to a restaurant and it tasted like my mom's cooking, I'd run out as fast as I could.
@atmasphere if the increased ratio of second and/or third order harmonics in tube equipment masks the higher order harmonics, are you also saying that the frequency response of tube amps in the highest audible frequencies is NOT lower than that of SS amps, but we just don't "hear" those higher frequencies because they are masked by the 2d/3d orders?
