I am not arguing that you don’t hear a difference. But why are you hearing that difference? Anyone have any insight to that? What does that audiophile quality switch do that makes it better?
@charliech What you’re completely missing here is noise, among other things, which is critical in an audio application and not as much in industrial applications. Add a better linear power supply to a switch, router, or streamer and you’ll almost certainly get notably better sound quality than using an onboard SMPS. Also, audiophile switches, streamers, etc. employ other components to keep noise, jitter, etc. to an absolute minimum because in streaming minimizing noise and using better clocks is huge. Full stop. I know on its face it seems a bit odd that these things should make such a significant difference in getting better sound, but they just do and there’s really no getting around it. Embrace it or deny it, that’s entirely up to you.
