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).
Some distortion does make for a more relaxing, involving sound. An LP through a nice tube amp puts me to sleep with the nice tone and sound. If I’m off track, sorry.
I remember listening to records on tube amps long time ago, then in the solid state sound, it went away, the sound seemed not as relaxing, and it was harder to get that relaxed fall asleep feeling. I use the tube (1 ohm resistor) tap on my Sunfire a lot, to get that tone, it’s close, but not the same as a nice tube amp/preamp, LP playing. I do miss that tone, the Sunfire tap brings me close, but it’s not the same. I do miss it.
