The Truth About Power Cords and there "Real" Price to Performance

As I can only speak to my experience with several manufacturers/ brands over the years -  the best results I have had from Power Chords are 

Stage 3 Concepts, Kraken

For those that care...
In 2018 /2019  I made an investment into computer audio. I have been skeptical about the benefits vs limitations of the technology. I had a Mac Mini Modified with a separate power supply, and external clock. My overall impression was that it was O.K. it did not sound half as good as my CDP set up but it sounded respectable for the 4k I put into it.

Out of curiosity I decided to hook up a Stage 3 Concepts Kraken to the Mac Mini set up. There was a moment of disbelief as it sounded almost as good as the CDP. The difference was not subtle and was by far the best I have ever heard computer audio sound. It only took a Power Cable twice the total investment cost to get the Mac Mini to perform and exceed expectations.

Not sure what the difference is between it and the standard MC.

Vista1868 commented about system quality symmetry with interconnects should equate likewise with power cords.

A quality, clear stream of power coming into a component is not the same as a signal stream from that component. In fact, in simple terms, it only empowers the component’s ability to do what it can...nothing less and nothing more. It will not emphasize its flaws.
As for an excellent power cord regardless of price, check out Grover Huffman’s. I’ve tried several cords and his performs just as well as the high cost standards by Audience, Nordost, Audioquest, and the other usual suspects. It’s true.

Mike Morrow asked me to post this. He was one of the 27 cord companies Jay Revied.


Regarding power cords, we at Morrow Audio also do not fully understand howthe last few feet from the wall outlet to the equipment can make a difference. But, it is a real thing that can be heard. My personal noticeis that most power cords that come with equipment are made of poor quality copper, so replacing with a good qualitycord will make a difference. There is also a lowering of the impedance when using higher gauges, providing a betterpower transfer to the equipment. The connectors are likewise of much higher quality than the equipment manufacturerprovides, again providing better contact and power transfer. RFI can likewise influence, this lessened with propertwisting of the wires like in our power cords. All these things add up, providing the sonic changes and improvementsthat one hears. - Mike Morrow
