Do CD Transports benefit much from upgraded power cords?

"Perhaps not permanently..."

The three huge radio towers have gone, and there are houses there now. I do know a street in Canberra where all the houses have been vacated by order because of high radiation risk. Did not stop us working the other side of the road, in clear sight of numerous defence satellite dishes.

I do have an absolute example where modifying a power cord causes a digital signal to become unintelligible. I have a KEF subwoofer in my motorhome which can be powered by mains, or via a battery and inverter. When switched on, with the standard power cord, the class D amplifier in the KEF generates so much RFI down the power cord, it stops my TV receiving digital signals over-the-air.

Modify the power cord by adding two ferrite chokes and the RFI becomes benign. This is entirely objective, and repeatable. No subjectivity required!

My take: stop worrying about the noise coming in from the mains, start worrying about the noise your components might generate

@luvtubes69 ​​​​@grunge1000 could you please list your systems and the power cables you have tried that made no difference on any of your components?
Please…you continue to argue so it’s a good idea to substantiate your statements. Let’s see this info. If you haven’t tried you can have an opinion but it’s baseless.
And if you argue that you would like to understand why power cords make a difference I explained it in my earlier post and so did @richardbrand

Read it. If you don’t understand it is one thing. But if you continue to ignore the information provided to you and you continue to pound this thread with your “I think” theories without any experience, may be it is time to get back to ASR where Amir does all the thinking for you. Easier that way…don’t strain or burden yourselves.

There is a great video by the founder of Sunyata that explains in detail why the water analogy is just wrong. Here are a couple brief comments. When I have time I'll see if I can find the video... it is very enlightening. 

For me, the jaw dropping difference with good power cords was enough to convince me they were worth it.

Misconception #1: AC Power is like water coming from a large power tank, flowing through several 10s of feet of power hose into a component. This implies that the component is at the end of this system.

Answer: “Actually, the component sits between two power conductors: the hot and the neutral. AC power oscillates (alternates) back and forth at a 50-60 Hz rate. So power does not pour into the component at all. The component's power supply is within a complex network of wires and connectors. ALL of the wire and connectors can and do affect the performance of the component's power supply.”

Misconception #2: AC power can be contaminated just like water in a hose. This implies that once the water is contaminated at some point up stream, that is must be cleansed before it arrives at the audio component.

Answer: “As stated in #1, the component is not at the end of the power hose. It is between two power hoses and the current is oscillating back and forth. Further, current is not like water at all. Electrons cannot be contaminated. There are two aspects to power transmission: the electromagnetic wave and the current flow. The current itself cannot be contaminated but the electromagnetic wave can be modulated with other frequencies. We usually call these other frequencies noise or Electromagnetic Interference (EMI). Within the various parts of a power circuit there may be EMI in certain parts that is not present in others. Electromagnetic energy can be transformed or redirected to lessen their effects.

"Some power cords use capacitors, inductors, or ferrites in an attempt to control the electromagnetic fields around the audio component. The success of such an approach is completely dependent upon the specific design and the reactance of the power supply of the component to which the power cable is attached.”

Misconception #3: There is up to a hundred feet of wire in the walls, so the last 6 feet of power cord can't possibly make any difference.

Answer: “The power cord is not the last 6 feet, it is the first 6 feet from the perspective of the component. As stated in #1 the local current and electromagnetic effects directly affect the sonic performance of the component.”

"Prove it, bro!"

Ummmm, I've proven it to myself for years now...It's easily demonstrable. 

I'm not here to prove anything to anyone. YOU prove me wrong.

@audphile1--Why? What's the point of listing my system and PC's that I have used. What information has been given that statistically proves that PC's have an impact on sound? I can tell you that my Personal Computer PC is special and it makes my computer runs faster than an 10 Ghz AMD processer--Is that proof??

You are all just grasping as straws here. I am glad you hear a difference but I have not and science dictates that I shouldn't. Again, I am not some ASR junkie, but I am a scientist, so I want some scientific rigor to substantiate your claims. 

@ghdprentice --Please. Talk about a biased opinion. They have some really neat tech that is applicable to Power Cords but statistical tests that prove that these cables make a sonic difference is lacking. Again, I would love to see a sonic uptick so I can further my journey--The proof is in the pudding so to speak. 

Kindest Regards,
