Raspberry Pi 4 sound quality

[Edward]

I have Ropieee running Roon on a Raspberry Pi 4 (4GB RAM) with an Allo DigiOne Signature Edition hat into a Chord Mojo and Naim XS. The excellent sound has marginally more detail and improved dynamics than my Pi 3B with the same hat. 

I was hoping to achieve better sound quality using Moode Player. What is surprising and disappointing is the thin sound lacking in midrange and bass from the Pi 4/Allo combination when using the latest Moode Player 5.4 Beta2 instead of Roon. From memory this sounds noticeably worse than the Pi 3/DigiOne Sig. Ed. running Moode 4.

This doesn’t make sense to me unless the Pi 4 is capable of degrading the sound in some way, which is a major concern. Does anyone have comments on Pi 4 sound quality?

I'll be commenting soon, I have a DigiOne Sig too as well as Roon. I've used Ropieee, I like it as an end-point. It seems to me that Arch-Linux all by itself sounds better than Debian when other variables are kept the same....for example Ropieee vs Raspbian w/Roon end-point installed. Even MPD via Arch sounds better than MPD via Raspbian. At least to me.

Of course, everything sounds better with my OS tweaks installed, even Ropieee.
