After „closing“ of Innerfidelity, it was a bit difficult for me (try and error) to find good headphones.

Doing IEM measurements is easier because you only need to create a pressure chamber between the IEM driver and the measurement mic and maintain the same distance between Mikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.comtag:blogger.com,1999:blog-4781727111866727703.post-20585592533625066702021-04-11T06:12:35.909-07:002021-04-11T06:12:35.909-07:00Nice review.

One thing that concerns me about EARS is the fact that it's a separate DAC with no world clock input. That means, there is a clock skew for sure between EARS and your RME used for output. You can check that by taking measurements in REW with different sweep lengths. And having a clock skew means you need to discard phase information Mikhailhttps://www.blogger.com/profile/03247181793198240403noreply@blogger.com
