Do CD Transports benefit much from upgraded power cords?

I could do me some Lagavulin.......just saying. And a little DSOTM on SACD upstairs on the Yamaha CDS-2100..

"Prove it, bro!"

Just not worth arguing about.

"Doesn't amperage play a part in this? I also don't see the correlation between changing the power source with changing the power cord"

Many of us have to make do with 240-Volt mains supply, so already need less than half the amperage of the 110-Volt crowd!

I am proposing an experiment where an AC mains power supply (which happens to be external to the transport and converts AC to 12-Volt DC) is replaced by a 12-Volt battery.  The AC power cord is not just changed, it is completely removed.  The mains AC, with all its alleged noise, is also completely removed.  If need be, the battery and the low voltage cable can be shielded by a Faraday cage.

12-Volt Amperage consumed by the transport would be unchanged, and quite small.

Personally, I would expect the output from the transport, as delivered via HDMI, to be indistinguishable at the bit level.  But there may be an impact on other components from the removal of the wall wart (switched mode power supply).  Not bought from Walmart!

Ah, now I get it. Thank you.

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!
