Ghdprentice make a good point...
We all came to audio and go through it with different perspective...
In my experience, to have dynamic right, to have "pace and rythm" optimal, and to have "timbre" perception right, all that go together in a dedicated room ...For headphone it is not so straightforward... As i said i think it is not possible to have a beautiful natural timbre experience without good dynamic from the speakers" room...But for headphone it is different... For example the bass perception and dynamic of my SR-5 Stax gold gave a sublime timbre but was not on par in bass and dynamic with the Hifiman HE 400...Headphone are not speakers/ room...
ghdprentice awake me to something i did not thought of beginning my thread : we all come with our own history and musical taste even if acoustic concept did not change...And headphone are not speakers when we experience them...
And for sure someone coming from jazz or rock mainly or from classical music, will not optimize at first his audio system with the same set of ordered priorities and acoustic factors ...For example in my room i never prioritize bass depth... My speakers never go under 50 hertz...
But i realized what i missed with heaphone able to go 30 hertz with clarity... 😊
But at the end the question which emerge is how my audio system disapear
letting music be...It is an acoustic and psycho-acoustic precise question, and it is called immersiveness...
i will wait for others experiences and opinions..
I stumbled on an interesting video which is for headphone but can be applied for speakers it is about the way to assess basic qualities of headphones, but the same tree of concepts apply for speakers...
