If using Disabled try lowering the maximum Alsa output volume in that setting...reduce by 6db to start and check.
Hardware, if available will be better than Software and if you have downstream volume control then Disabled may be an option. (Note the warnings if you use this.)
Symptoms do sound as though the input is being overdriven/clipped.
I tried to lower the ALSA maximum volume: at lower volume the saturation/distortion effect lowers, but in the same way it does by reducing the volume from the amplifier. Moreover the volume level is almost the same between the moode/raspberry and the JRiver/Windos laptop (in which volume level is also set to fixed value). So I dont't think this is the main issue. Morover there is not clipping.
I tried to supply the Raspberry with an other power supplier (a universal power supplier for notebooks, which also has a 5 V USB power output): maybe the sound is a little better, but it does not drastically improve.
So, I will now try to install on another SD card a different software, such as Volumio, and ear if there is any difference...
I'm not really interested in hosting Threads comparing Player softwares because there is no benefit to our project in terms of being able to find or fix bugs in moOde software, gain insights, etc as a result of such comparisons.
This Sound Quality thread is mainly for a lively but respectful discussion of SQ related to moOde software, Raspberry Pi hardware, audio boards, objective vs subjective, perceptions, etc. Sometimes we uncover bugs as a result of the discussion but mainly it's an interesting and enlightening flow of peoples experiences and opinions with this wonderful Linux audio space.
If you want to compare Player softwares do it in Forums like diyAudio or similar. There are already ginormous threads for moOde vs Rune vs Volumio vs PiCorePlayer vs Roon vs JRiver vs etc etc etc.
