Hello fellow Audeze fans, its coming down to the number for me. Im about to buy the LCD-X this month, but ive wondered something and id like to get your input. Do you think the lcdx would benefit more from being closed or open? I dont mind if dynamic drivers are open or closed. But i feel like planars should only ever be open.. unless im wrong in that way of thinking? any shared wisdom would be appreciated. Also has anyone done an A+B with the open and closed version?
