the magic of power cords


We need a bit of magic in our lives. It might be the reason why audiophilia has such traction among people from all walks of life.

The neophyte's skepticism is likely proportional to the level of technical training - the more you think you know, the stronger the conviction that, for example, the power cable business is a sham: "electrons are electrons" and "if the house cabling is bad, why would the last 3 feet matter?". The stronger the conviction, the more humbling the experience of hearing the power cord magic in action.

A few years back a Sophia Electric amp came into my hands with what looked like a generic power cord. The few non-generic cords I tried (Audioquest AC15, Audio Magic XSteam, Shunyata Research Diamondback) made a significant difference for the worse. The thin, black, generic-looking original cable allowed for a clarity and definition of voice and instruments that got totally washed out with the aftermarket cables. A night-and-day difference. No doubt - the power cord made a huge difference - but not in the expected direction. The Audioquest AC15 was particularly bad.

For awhile, I kept trying them around on all incoming equipment (be it DACs, preamps or amps). The AC15 sounded so bad every time that after awhile I wasn't even trying it out.

Many years and few amps later - something seemed not quite right with the presentation of my KAV-300i: slightly dull upper bass. Power cord: Zu Birth. Finally (after multiple interconnects and few speaker cable swaps) I pull out the power cord stash (same as above). This time around the AC15 was the great surprise: it allowed for clarity and macro dynamics well above the others.

What do I learn? Nothing, really. When is shielding important? When is gauge? How about the conductor or the insulation? How come there isn't one "best" design?

The magic continues.

I started testing many powercables in 2002. I had and still have a lot of fun testing them. That time I worked in a speciality shop in sound and vision. I wanted people to understand how big the influence was of a powercable. So I started blind tests. I Always used a very expensive powercable and our most sold one of about 100 dollar. Most of the time I used sources, but also I did it with amps. For example a source of 2000 euro with a powercable of 2500 euro. I compared it with a source of 5000 euro with a powercable of 100 euro. It was a lot easier to get a better end result with the use of an expensive powercable. People Always were very surprised. This is how you can people make aware how big the influence is. That is why you need to keep things as simple as possible!
When the Valhalla powercord came out I could live for about one year only by selling these powercables. It was so much fun to sell them. These days there are more exeptional stunning powercables.
for all: Nay and Yes sayers. It still doesn't make sense to play with these differences for extra money. It would partially make sense if aftermarket PC is in $50 range or bellow.
Expensive powercable make sence when you get a better endresult with a 2000 dollar costing poweramp or source with a 3000 dollar costing powercable. Compared to a source or amp of 5000 dollar with a 100 dollar costing powercable.

When you do this in blind tests people will understand the value of a powercable. I do this for about 12 years now.
