One thing is sure for me ...
Since i created my last small room with the less costlier of all the speakers i ever bought , i am amazed by the results of my modification on them and by a so good sound ( not high end for sure😊 i dont claim the impossible here ) from so small self powered speakers ... Timbre is not bad but even good , soundstage encompass me and include me and the imaging is good... So much i listen music amazed and happy ...
A minimal acoustical satisfying experience is possible passed some threshold of mechanical, electrical and acoustical optimization ..
I am proud of my S.Q. cost ratio and i am not jealous and desesperate by bad sound as it was in 2000 when i was owning no amplifier nor any dac anymore , and when i decided to go headphones... But no headphones ever satisfied me in spite of all my modifications , nor any speakers till i learned acoustics by experiments ..
Now i know enough , i was able to recreate a second system modifying the speakers porthole and tweeter and modifying my best headphone for the better ...
I am happy and proud ..
learning and creativity over big money ...
