I can assure you the Akg K340 are now optimized and so good i will never go back to the difficult task to tune a room... I dont need because the three dimensional "out of the head" soundfield of my headphone beat my past speakers or rival them ...
The K340 is unique headphone the most different designed headphone ever compared to any other... Read about it...
My best to you and your family...
thanks @mahgister I hope you are enjoying the music whichever ways, maybe nearfield listening with speakers is an option too!
