But there may be an impact on other components from the removal of the wall wart (switched mode power supply).
yes. You got it! Nothing exists in isolation - it’s an ecosystem. I talked about it in my earlier reply to this post and I think we’re on the same page.
I’ve been using aftermarket power cords on CD players, CD Transports and network streamers for years. I have not heard my system sound exactly identical with different power cables on digital front end. As a matter of fact I had just tried 3 power cables on my Aurender N200 streamer and they all resulted in different sonic presentation. And Aurender N200 has a really nice and solid linear power supply and is plugged into a dedicated circuit. I don’t do quick a/b. I run cables for at least a day before I evaluate. But…to each his own.
For those who like stock powrr cords and SMPS, cool by me. Your thoughts and beliefs do not affect the sound of my system in any way. Enjoy the music!
