My system is so satisfying that it is final...
Active speakers with 6 modifications i made and i place them in their acoustic corner : M-Audio AV40..

My main system :
AKG K340 modified and optimized , Hidizs AP 80 pro battery dac ...
Sansui Alpha 607i as amplifier for them ...
The last time i tried to upgrade appeared as an error...
One of the best dedicated headphone in the world never beat my Sansui headpone out ...
why ?
Because an electrical synergy is not an acoustical experienced synergy ...
You can have a measured well done electrical synergy and a bad acoustical synergy ...
A good acoustical synergy implicate an electrical synergy but an electrical synergy dont necessarily implicate an acoustical synergy ...
it is especially true with an hybrid headphone with inside an acoustic device and a dual acoustic chamber...
i will replace a defectuous component perhaps but i will not "upgrade"... the reason is simple , i am on the minimal threshold of acoustic satisfaction , to go on the optimal acoustic satisfaction threshold , i will go from 700 bucks system to over 10,000 bucks at least perhaps 15,000 replacing each part ... It is meaningless because the distance between these two acoustic tresholds is less than the distance from regular not well embedded system and really well synergetical and well embedded one generally ...
Those of you with costly system , dont think i am deaf .... i was able to mechanically tune my room... Try it ... 😁
