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.
Bluesound Node to Topping E30 to L30ll on main setup. PC to Schiit Modi 2 to Magni 3 on secondary. HD 650 and HD 6XX, depending on what’s closest. Fiio KA5 on iOS devices with either of the above headphones or Momentum 2.0, depending on mood. I have a pair of HD 660S2 coming tomorrow. It never ends.
I must ask why do you have 650’s and 6xx’s
I got the MassDrop 6XX for Christmas a couple of years ago and heard they were basically a 650. When a great used deal came up on the real thing, I grabbed it to do some A/B comparisons. Yep. LOL. Pretty much the same.
