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.

Hi Bo, you're just telling stories about a fantastic character named "Bo" in Holland, aren't you?

He certainly can spin a story, can't he? He's obviously a dealer....and maybe a future politician???

If there is one thing I'm sure about in audio its that that hunk of wire that sounded terrible on one piece of gear will sing on another.

Well said Schubert, it seems as if we have reached similar viewpoints. I have played with enough cables and cords to realize that it really is all about synergy, the *magic*. I have heard cables/cords that I previously thought were dreadful, sound amazing with certain gear. I have also heard my favorites sound terrible, worse than stock even, when placed on certain equipment. There is just no understanding or predicting the rhyme or reason in this equation. The only true test is in the listening.

How much better will a $250K 2 channel audio system sound than a $50K system? Five times better? How about twice as good? Or maybe only 5% or 10% better?

My vote would be for the latter choice, 5-10% improvement. Of course I have not compared a $50K system to a $250K system, my answer comes from comparing a $20K system to a $120K system.
IMHO, to even be twice as good, the less expensive system must be defective or set up improperly. The law of diminishing returns hits very hard and very early in most things in life, including audio.

How do you tell which aspect of the system falls short at one given moment (without going through the straight A/B)? Does a shortcoming in PC (blur, boomy bass, etc..) sound different to you than a shortcoming in IC, SC, room etc...?

I would say that a shortcoming can be difficult to address if you are unfamiliar with the system. That is why it is critical to be familiar with your own system, and only make one change at a time. Change a power cord, and then listen for a few days, are things better, the same, or worse?

The biggest mistake you can make is changing too many things at one time, though most of us have done that. Buy a new amp, some cables and some cords, then insert them all into the system and the sound gets worse....then you have no idea what is doing what and who's making the sound worse. One change at a time helps to alleviate the guessing game.

Jmcgrogan2, if I understand correctly, basically you feel that "no, prior to engaging in swaps, etc.. one cannot tell which component, cable, etc.. is mostly responsible for what shortcoming of the overall sound".

I would agree with that. If I walk into a strange room and the sound is good or bad, how would I know which components, cable or cord to credit or blame for the sound?

The logical path is to proceed changing one component at a time and note what we think of the change. However, we do not always proceed in a logical manner in this hobby. ;^)
I see... the I's have it. I was going to post more, but I have to go eat lunch. Then I have to stop by the Post office, I have some packages. I want to get some stamps too. I will listen some more when I get home. I love listening to the music I enjoy. I know others who love music as much as I do. I love freedom too, I also love myself. ;^)
One person's "0.2%" increase in performance is another person's "night and day". I never understood how people could quantify differences anyway.

I either think it sounds better or worse. Then there are varying degrees of better or worse. How can anyone say this power cord offers a 3.14159265359% better performance over that power cord???

That is the reason I only sell the best in every single price tag.

Wow, how rare is that? A dealer who sells only the best at every single price point.....hmmmmmm. ;^)
^^^To make your long reply shorter Bobby, no, you would have no idea what was wrong either, just as I replied to this question on 4/7/14. Remember, Cbozdog wants to know if you walk into a unfamiliar room with an unfamiliar system if you can immediately determine what component needs to be upgraded. Yes, I'm sure you have heard a lot of gear and cables, as have I, but I'm also sure that there is much out there that you haven't heard. The key word here is "unfamiliar", which means that you have no history with the equipment or cables, or room for that matter.

Now let's simplify it for you. You walk into a strange room full of gear and cables that you've never heard before, could you guess the component that could be upgraded to give the best benefit? It's really a yes or no answer we're looking for here. I'll cheat and answer once again that no, in an unfamiliar room, with unfamiliar gear and cables, I couldn't identify the culprit.

I've been in this situation before several times, when going to audition a piece of gear that I'm interested in buying. I may have never heard the gear before, but I'll admit, if I don't like the sound of the system, I won't buy the piece of equipment/cable, even if that is not the culprit. On the other hand, I have been blown away by the sound of a system, bought the piece of gear, only to find that it didn't sound as good in my room. Synergy is critical, and that includes the room as well.
