Headamp 6 Pro : Very good amp for headphones

I'm using this amp as a distribution for the headphones inside my home studio. Got no audible noise, handling is really easy and the amplification level is enough for any headphones I have in my studio (I've got several brands with different impedance).

The mixin bus for each channel is not so convenient in my case, because I can't use effect bus for both AUX and Main channels on my mixer (works only for Main in my case). Because of that, I can't really blend AUX with processed Main (which is processed in most cases), it creates additional sound effects, which sounds weird and creates discomfort for musicians. But that's the mixer problem.

Also looks solid and professional. I'm very satisfied so far.
