I am wondering if anyone know this. So I am using Ember to drive my Beyerdynamic T1, which has 600 ohm impedance but to be considered fairly easy to drive compare to other hard to drive cans. The thing is no matter how I change the output impedance of the Ember, the gain or the sound signature of T1 will be the same. The sound won't change with the different output impedance settings like other cans. I also tried different tubes like 6sn7, 12au7, 12ax7, 6dj8 and the result is same. I mean, the sound does change with different tubes but not with different impedance settings.
