Power Cords Snake Oil ??


Having been a long time audiophile living with countless high end compnents I have to wonder about the theory and practicality of high end power cords.

I have yet to hear the difference a power cord makes. Ive owned, synergistic, Shunyata, BMI and cardas. I in no way can detect any sonic signature or change. Give me a pair of interconnects and I imeadiately notice a difference somewhere in the sonic spectrum. Not the PC though. I have accomplished 4 blind tests with my friends. 3 out of the 4 they did not know their cord was replaced. All 4 were using a stock factory supplied cord. Each of the 4 tests were done on different components. Amp, CDP, Preamp & dac.

My electrical backround tells me that provided you supply the component with its required voltage bet 110vac or 220/240vac its happy. Now, change the incoming frequency from 60hz to say 53hz and watch how quickly your soundstage collapses.! This is often the case during the summer months when home air conditioners are in use and the utility company power output is taxed to the max. A really good power conditioner should however take care of the frequency fluctuations. But 110vac is still 110vac regardless of the conductor it passes through as long as its remains 110vac when it reaches the intended circuit. Does your 8k amp or preamp know the difference of the path the voltage took to reach it ? Many an audiophile will use a dedicated 20amp circut for their equipment.That is a good idea as voltage & frequency fluctuations will occur in the home circuit to to other loads on the main breaker panel but again, A power cord simply is the means of transporting the voltage from the wall to the component. IF there is a clean 110vac @ 60hz at the wall socket, no matter what the medium is to go from the socket to the component, it will still be 110vac @60hz.

Could somebody expand on this a bit more. I just dont understand it. ??

Why power cords, wall outlets, wall outlet covers, power cord plugs, contact enhancers on power cord plug contacts make a difference to the sound is one of many audio hobby mysteries that alter and illuminate our times. Obviously, having more stable and cleaner power delivered from the factory would help as would having perfect weather 24/7. And having all the wires in the correct direction. Unfortunately, for most of us, you get what you get. 
Nobody has considers what is behind AC wall receptacle and what kind of power is coming to that receptacle through the wires. Even if you pull completely new 20A line from breaker box to your HiFi (which is probably most efficient thing you can do) there is no guarantee what kind of power is coming through that receptacle. We are trying to fix the consequence of imperfect electrical grid by spending hundreds and thousands of dollars on 5 feet of cable. How can 5 feet rectify hundreds of feet of imperfection and cost cutting processes. I am all for making improvements, but within reason. Here there is simply lack of valid reasoning.
Romex has extremely good performance, so actually the real problem is at the outlet and beyond. Romex is not legal for power cords as it is too stiff. But in the wall it works great.

IOW the power cord doesn't 'rectify hundreds of feet of imperfection' because it doesn't have to. It is important for a power cord to be competent though. FWIW, that has little to do with price. The effects of a power cord are often measurable. I've seen them rob an amplifier of about 30% of its output power due to voltage drop across the cord!

What was the cord made of, paper mache? Why would one cord have a 30% drop but another 2%?

Oh, great, let’s go back to the Stone Age and use aluminum wire for everything. What is this, the Flintstones? Aluminum for transformers, internal wiring, tone arm wire, inductors, interconnects, cartridge wiring. Aluminum for electronics chasses. What’s next, oxygen free high purity aluminum? Six nines long crystal aluminum? Oh, my! 😬 Quick, somebody alert NASA, tell them to ditch those horrible gold fuses in satellites and spacecraft and switch to six nines aluminum ASAP. 🚀
