... yes... just sayin'... there's more to power supply than the AC input.
"If the power supply output ain't pretty, neither is the sound generally."
Audio electronics operate off DC. The conversion process from AC to DC has its own sonic consequences. And converters not only have their own signatures, but react very differently to various mains distortions and anomalies. It's a convolved situation!
These situations remain uncovered in both textbooks and vestpocket engineering. But we DO have some measurables -- lol.
Batteries bypass both aspects. Hence their utility.

PS I wrote a longer, probably better version of this note but just as I hit "Post" the wireless connection went down, and apparently this site is not engineered to save. [Sigh]Rerurn to Romy the Cat's Site
