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.
Sennheiser 660s2 paired with an ifi Hip DAC2 Gold edition is my daily setup. Very happy with it. I also have mobile setups, buds 2 pro or a set of porta pro with yaxis fed off a btr5.
