My main gear currently are an Ifi Zen DAC and some nice Hifiman 4xx plugged into them.
No matter what, I keep coming back to these two. I have other gear, not this is the one that pleases me the most. It is not my endgoal, but it’s superb to my ears.
I’ve had the pleasure of trying the HD800S and I loved them for certain types of music. But I couldn’t see myself using them daily. Maybe for gaming. But I fear they’d end up hanging on the wall as an art piece. Which they sort of are.
