HypnoCatMusic,
Thanks for submitting your profiles request for your Hifiman He400’s. I will add it to our acquisition list, although they do seem to be out of production. We create every profile by hand/ear which means we must have that particular piece of hardware on our bench to tune. When this device is made available to us we will create a custom profile for it.
Also, I’ll pass along your feature request for a few more EQ adjustment points.
Thanks,
Dan Rice
