Oh god i didn't know this thread exist. I'm blessed i still got a chance to test this sublime headphones
Out of the Centrance M8 it sounds good already but still lacking some power even high gain is used. Then i changed to Marantz 5004 CDP - Bakoon 7511mk2 and the sound was mesmerizing. Very neutral, very linear, AMAZING timbre, yet sounds so natural and so musical to the point it made me lost in the music. I don't know how the Sennheiser Engineers able to made this headphones, it's a bit sad nowadays Sennheiser are moving toward a different sound.
HD540II, truly one of the most important headphones and yet so underrated, it may not displayed ultra detailed, showing ultra clean, ultra precise or ultra trebly sounds which failed to impress some of the people, only me and the owner ( there were 6 of us that time ) that can grasp the point of HD540II
This thread is awesome!
A little off topic : how do you know your HD580 was made in germany, by looking the "Made in .... " in headband? Does it sounds different than the Ireland made one? thanks
