Audio nowadays is no more electronic enginering first but acoustical engineering first....
I think that is an accurate statement. It’s not hard to acquire really good gear that works well together these days at all. Streaming in particular makes it a breeze. Audiophiles tend to live in the past and make it all seem much more complicated than it need be these days.
However, getting things to sound best or even good in one’s room is almost always a challenge still and very much worth becoming educated about. Nothing new or different there. That should be about 90% of the battle I would say. Maybe more if you are really on your game. The rest is largely subjective and largely based on always widely-varying personal preferences
Maybe that’s why headphones are so popular? Portable and no room to deal with to boot. You will get some consensus there about which ones are good or not but still little consensus about which are truly the best.
