SQ difference - Raspberry Pi vs x86_64?

[Snoopy8]

@hkphantomgtr interestingly, Google AI gave me this reply

Batteries typically exhibit a slower dynamic response than linear power supplies in audio applications, leading to a perceived slower, less dynamic, and less articulate sound. This difference arises from the inherent characteristics of both power sources and how they interact with audio circuits

@uglymusic, previously, I was concentrating on improving the end point more so than the server.  But once the end point has reached a certain level, then changes to the server become more apparent.  And my reported comparisons between the Pi5 and NUC have all been as the server (running LMS).

Any comparison between my Pi5 and NUC as the end point will be unfair.  My end point NUC has a JCAT USB XE card, with its own linear supply, CamillaDSP running Audiolense convolution room correction.
