Hey,
I got an iHA-6 (Loaner) here actually. I've been experiencing some crazy things over the past few weeks.
I also think I read something about it here. however, can't find it anymore!? Among others from
@Andykong, if i remember right.
It doesn`t matter, which headphone, cable or hp output i use. I rule out the connected dac and interconnects as well.
Starting with the iHA-6 at Low Gain/ High Current. Sounds the best to me using HFM Arya f.e.. I get a clearly perceptible hum, when i switch to high gain, low gain is silent.
But sometimes it is the other way around. Hum on Low Gain, nothing on high gain. Current mode the same. Depending on the song, bass or whatever it triggers, i get a sound like bass distortion and/ or a hissing noise. Changing gain and/or current back and forth usually fixes it.
If i use dynamic driver hp`s f.e., i get a hissing noise/ a bit like pink noise (no hum), which sounds really weird. Switching modes usually fixes this too. But high current for dynamic drivers?
Also here, the other way around from time to time. So, no clear procedure overall.
Any suggestions as to what it is or how to fix or even prevent it. A defect?
Thank you.
Cheers

I'm going to put this together from the forum below to get to the bottom of it all.
