Headphones = less headache. I understand that you can doctor and Taylor the sound to your liking when you deal with a loudspeaker system with room acoustics and speaker placement and swapping cables, etc.You are wrong...
However, the money required to get it right is vastly greater than the money spent on a good headphone system.
Acoustic is a science and it is not NECESSARY to buy costly acoustical product AT ALL....My own acoustical treatment and devices for acoustical controls cost me long time experiments but no money...
You are right about one thing it is simpler to use headphone than upgrading toward costly gear each year hoping to replace acoustical control, mechanical control and electrical noise floor control with new gear and always ending inevitably in frustration because we dont know that no system can be good in a bad room in an uncontrolled vibrating location and in a noisy electrical grid...
But if you had read me my 500 bucks audio system beat my 7 various headphones... the reason is embeddings controls of my system at NO COST....
Then if people chase their tail it is because most people are conditioned by the marketing ploy to upgrade and not informed on acoustic nor on simple science...
I apologize if my post seems rude...
My best to you....
