Case in point I tried to paired my hm901 LO with the Dynaudio xeo3 but unfortunately the LO level is too high and resulted in clippings. With DX50 I can adjust it.
The variable LO is due to the fact that volume is controlled digitally, straight on the DAC chip (like on the DX100). This gives you very precise control, no channel imbalance issues and the amp stage can be kept at a constant level, not having to worry about analog pots causing noise or crackling.

Yep, mine clicks as well.
Regarding hiss: I think we need to agree on a definition here. In a quiet room, with no music playing, I can tell the difference between the player being on or off - using iems, and I have to listen for it. The "sound" is constant, regardless of volume and gain setting. It's not a hiss or a hum, more like insanely low volume white noise. When I talk about "hiss", I'm talking about a constant "SSSSSS" noise like the Studio V (not 3rd ani and all that) with iems. I can produce "hiss" like that on the DX50 if I use sensitive iems and turn the volume past 240, while playing the "silence" track. If I played real music at those levels I would most definitely damage my hearing and probably my headphones as well.
