Do power supplies actually affect sound quality of standalone CD players? 2019-04-11 14:08:53 I'm a fan of CDs. I like the format and I like owning physical media.Recently I bought a used Magnavox CDB 482 CD Player, because I got it at a decent price. But you can't have an online conversation about a piece of hardware without some placebophile showing up and telling you about how you need to spend more money to make things sound even better.Do placebophiles ever sit and back and enjoy the music they own?Yesterday's placebophile was a long detailed discussion about how the power supply in this CD player affects the sound quality and recommended all sorts of upgrades to the power supply to "optimize the sound."Another placebophile recommended that I rip all my CDs and stick them on a Raspberry Pi and power it off a battery pack to take the power supply completely out of the equation.How much can a power supply really affect sound quality of a CD players (or any other audio component?)I'm sure a really bad power supply can add interference. But there has to be a point where you're replacing expensive components to get things to measure better on some instrument, but the difference is inaudible.
