I just ordered the UM3X yesterday, and the main thing I'm afraid of is the hiss you are describing. I had the UM2 and was often annoyed by this. Hopefully this won't be a deal breaker, but we'll see once they arrive. I have an iBasso D3, but I rarely want to lug it around with me. It stays connected to my computer most of the time. I'll report back on my experience with the UM3X and my iPod Classic both amped and unamped.
