Phonitor ONE D
The best amplifier for headphone!
Incredible dac converter,you can mix your tracks directly on headphone thanks to the crossfeed parameter that allow you to improve the mono perception and to reduce the big stereo effect that every headphone have.
Amazing.
Too loud and detailed
I paired it with my HD600. It was a huge jump from iD14. I hear much more detailed now. The transient response is incredible. I'm afraid to lose my hearing because this thing can be super loud. I also like the crossfeed feature.
