Do CD Transports benefit much from upgraded power cords?

I power my CD transport with clean AC energy from its own nuclear reactor.  I use a small nuclear reactor for each component to keep the AC current cleaner.  😏

Interestingly I have access to a couple of Sony universal disc transports, which handle CD, SACD, DVD, BluRay and Ultra BluRay.  Each transport has two HDMI outputs, one purely for audio.  

Each is powered by a 12-Volt wall wart, so it would be very easy to substitute a 12-Volt car battery for the mains supply and do some A / B comparisons.

What objections are likely to be raised by the community, a) if there is no clear audible difference or b) if a clear audible difference is reported?

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.

@richardbrand ,

You’re likely NOT to hear a difference would be my guess. The Power Supply in those types of units are made with the cheapest parts that can be sourced. But, acknowledging your point, I never tried what you’re suggesting, so I can’t say for sure.

As I said a year ago, (when this thread was started), you’re going to need a higher-end unit with much higher end, heavier duty (usually separate for analog and digital) power supplies to hear a difference with a power cord change. I’ve tried power cord swaps on $699 MSRP players and didn’t really hear much of a change at all. I’ve also tried swaps on $3k+ players, and the change was immediate, and very noticeable.

I still stand by that. The change is real, but you have to start with something quality, not a $39 WalMart DVD player. Give it a shot, though if you’re feeling froggy. You can always re-hook the Wall Wart power wires back up with wire-nuts, lol.
