My system has all digital source components (stream Tidal on a Windows10 Pro machine, music server and CD/SACD transport) and external DACs. When I upgraded from a Furman power conditioner to a PS Audio P10 power regenerator (which removes most of the "distortion" in the AC power), I noticed an immediate improvement in the SQ from my DAC.
I can't speak to if improved power would improve a system with analog sources, but I suspect it would be a good upgrade for that as well.
