The Fosi Audio K7 is the gaming DAC/amp that took the crown for me because it’s clean, clinical, and powerful, so it stays out of the way and lets your headphones/IEMs do their thing. You get balanced output, a useful bass/treble EQ, and even Bluetooth—which is a nice bonus for an “audio hub” style desk setup.
Pros
+Clean, clinical sound that doesn’t heavily color headphones/IEMs
+Strong power output (up to about 2.1W balanced on high gain)
+Balanced 4.4mm output plus 3.5mm headphone out
+Bluetooth included for extra flexibility
+Useful bass and treble controls with EQ bypass
Cons
-Requires DC 12V power (can’t run only off USB-C)
-Bluetooth is older-gen (5.0) and not cutting-edge
-Screen angle can be hard to see on a desk
-Sensitive IEMs can reveal a noise floor, especially on balanced
