Just got my first portible dedicated headphone amp to get a little volume boost out of my dt770 80 ohm headphones.
I am playing music from my iphone 5 > cmoy > dt770 80 ohm, and I get horrible distortion with volume above anything louder than without the amp (straight from the iphone).
Is this normal?
The same thing happens on all my other headphones (krk kns8400, ath-m50, dt990 32ohm, beats pro), but they're all low impedance, so I'm not sure if that has anything to do with it.
I will email JDS after this, but I first wanted to see if I am expecting too much from a portable amp?
