Headphoneus Supremus
To follow up on my own post in regards to requesting a replacement, I would like to say that I'm very happy I actually replaced it.
I didn't realize there wasn't supposed to be any hiss with my Shure SE535's; with my new unit, even on high gain, there is no hiss whatsoever and I can now turn it on and off without pressing the power button hundreds of times (literally)!
Lastly, I thought I had messed up my music files or something due to the distortion/muddiness I was hearing, turns out it was just a defective player (I used the exact same sd card with all the same files).
Very glad you're enjoying it now.
