Head-Fier
I had no hiss with the Galaxy S9/Dragonfly Red and FH7s, but the Solaris is nothing but hiss. I love the convenience of a DAC/amp dongle, but as a Spotify user, dongles won't work for me until Android gets its USB driver to work right. The Intruder has 3 gain settings and a physical volume control, so it gives me complete control over the noise floor.
