I would say that audio hobby is a journey beginning with the wished basic gear synergy ending at an acoustic specific destination... it has ended for me... Lessons learned and applied... Music is my hobby as decades ago it was but this time with no frustration at all about sound because i learn minimal basic acoustics and few other things ...
it is called the minimal acoustic threshold of satisfaction or M.A.T.S. when each acoustic factors defining timbre, spatial qualities and immersiveness are there in a MINIMAL synergy state, this M.A.T. S. make us able to create the irresistible desire to never end any album we listen to....M.A.T.S. is the end of a journey...Not perfection which is anyway a result of acoustic knowledge more than the result of an illimited wallet... ...
If it is not for such experience,we became like a dog calling for a solution to some problem and mistaking another problem for the next solution, which upgrading is very often ; or worst, not recognizing the problem at all then staying frustrated and calling that the normal state of THE journey...
My two cents... 😊
Music is the wave and the sound and the gear are only the navigating surfer plank... Learn how to Control your body on the plank and dont mistake the plank for the journey...
