Low volume on headphone out.

[Matfarsan]

Is there a way to boost the output volume on the headphone out (Already max on the volume knob).
I feel like the volume is a bit too low playing with headphones.
Tried with both AT atm m50x and vic firth headphones.

I never had issue with volume, the module kicks out plenty. I have always used IEM buds though, I can comment on the ones you have. I know I didn't like the Bose Headphones I had as a birthday present once. But I found even Apple iPhone headphones decent enough. I guess it depends on what you and I consider loud enough. There could be an impedance issue.

As far as I know, professional headphone have a different inpedence to walkman type of phones, it's to do with audio quality is higher, but as a result, the max volume tends to be lower (I hope I have got this right!) That's why studios tend to have dedicated headphone amplifiers.
