Moode 6 sound quality

[energyi]

Had time to do some testing of several configs of my setup - NOS AD1865 DAC (hat) on RPI3A+ without special PSU.
Could use the amp Marantz PM6006 with speaker B&W CM6, what is better than my setup at home.
I will share my personal experience.

I tried to compare different settings of tweaks with moode version 6.7/6.7.1 also comparing to version 6.4.2 with tweaks made. In 6.4.2 I used
underclocking of PI, 64bit kernel, phils version of edwards tweaks and also some cmdline-adds.

Like other users described sound was more balanced in version 6.7 without tweaks than in 6.4.2 with tweaks on, what has over exaggerated highs.

Only playing with configs of moode 6.7 I avoid to use the script of edward. I used slightly underclocking and isolated cores for mpd and changes on mpd.service (schedule/priority/nice)

kernel:                32bit vs 64bit
CPUschedule:       other vs fifo
MPD-version:       21.24 vs 22.0
changes of NICE and CPUprio

My results are: most differences in sound are quite small. can't say if really better or just in my head ;-)
32bit>64bit
64bit sounds better with mpd-version 22.0.
21.24 <-> 22.0 sounds slightly different, but couldn't say that one is better
CPUschedule other>fifo, fifo sounds better with 64bit, but also 'other' is better than 'fifo'
with fifo - i prefered CPUpriority=60
with other - i prefered  nice=-13

also I realized that RTPRIO of MPD is fixed to 40 when using version 22.0.
with version 21.24 it is set to 50.

Would like if you can share your experiences. And thanks to Tim and everybody supporting the moode-project!!!!

Thanks so much for the thoughtful, time consuming review of settings. Really helpful.

Best,
