Hi everyone, and thanks for your feedback regarding my ZMF Atrium and its hissing sound - to me, this is (almost) a perfect headphone, just the hissing sound I experience won't let me enjoy it and focus on the music I listen to
In terms of my testing methodology, I have tried the following sources:
1) DAP - Kann Max - no hissing on ZMF Aeolus and ZM Eikon, hissing on Atrium
2) DAP - Fiio M17 - no hissing on ZMF Aeolus and ZM Eikon, hissing on Atrium
3) Desktop Amp/DAC - Topping DX7 Pro - no hissing on ZMF Aeolus and ZM Eikon, hissing on Atrium
I have checked two different cables, one balanced and one unbalanced, both sound perfect with ZMF Aeolus and ZMF Eikon, however ZMF Atrium generates this annoying and distracting hissing sound - it leads me to the conclusion that this is either some technical difference between ZMF Eikon / ZMF Aeolus vs. ZMF Atrium that generates it, or maybe even a slight difference that unfortunately generates hissing in my own ears only (but still, not sure why it doesn't generate it, while I'm on ZMF Eikon or ZMF Aeolus).
