Here is how I address your question. Every power cord is the same: Audio Sensibility Statement. The one to my PS Audio P20 and the ones to every component that plugs into it are all the same. I order lengths as needed. I do not vary or try others since settling on this cord several years ago. Incidently, I use that same cabling for everything else too, speakers, interconnects, everything. It makes life simpler. Plus I do not believe that anyone offers superior wire products.
A not sarcastic question for the power conditioner/upgraded power cord folks
And I realize that there are those that don’t believe in either
Assuming you use a power conditioner and after market power cords, do you feel that the power cord from the power conditioner to the wall might be a limiting or even a negating factor to the performance of the after market power cords that run from the power conditioner to the gear?
The reason I ask is that I was about to embark upon some more experimentation with different power cords and where I plugged them into when I discovered that the aftermarket cords I had purchased before and some recent arrivals are actually a meter shorter than the ones that came with the gear. This doesn’t matter for the amp due to its location, but when I did my last power cord upgrade I ran my CDP and pre into a conditioner so the length for those didn’t matter either, but as I was doing the musical chairs with power cords thing today, I also was intending to run the CDP and pre straight into the wall on separate dedicated circuits, but I found out that I am a tad short on those two.
Which doesn’t preclude me from moving my dedicated circuit outlets up a couple of feet, and I suppose I probably will, but I was curious as to the opinions about the limitations of a power conditioners power cord.
