That’s true. We all have different sensitivities and needs from our systems in order to be able to get a visceral feel from the music. We’re all unique in that regard....my wife and girls are just as happy with a crappy stock car radio, but I rarely listen to it,,,,it sounds like noise to me.
Many of us are fascinated by all the sciences involved with what makes the gear tick, and/or what’s required of the gear to allow us to get past the physics of the gear and lost in the music. It is indeed a "sub-hobby" within the audiophilia world, and it can be a very diverse journey by itself.
I suspect sub-hobbies are a part of many hobbies.
