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?
Hi Mapman, perhaps "free will" can be reason for trying? After all, a commonly accepted practice is the worship a supreme being not (yet) confirmed by science. Swapping power cords seems benign in comparison. For me, perhaps its magic compensates for my inability to adhere to more prevalent non-scientific practices and beliefs.
Hi Bobby (Bo), I enjoy your posts very much. You seem to have a good skill for listening.

Can you maybe explain - how do you listen to a new, unknown system to guess what is the component that can be upgraded to give best benefit? Without swapping components and comparing? I still feel that this might be possible for the best trained ear like yours.
"night and day"... on my end, it means simply "pleasure vs. lack thereof" when listening to the same tune.

To Onhwy61: "magic is applied technology that I don't understand". Thank you for your condescending remark my friend.

I'm proposing that magic is good. If there was a formula that actually worked, then the mystery would vanish and audiophilia would... (shock)... die off? No more cable-filled closets, mix and match gear etc...
I guess I have another question - it was on my mind for awhile and I don't seem to find a good threat already addressing it... maybe now it is more clear in my mind.

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 feel that they should sound differently to the trained, young ear (mine are probably not at their peak anymore in either respect) - and would be happy to learn how to make the right judgement call (or at least a better one).
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".

Swap one item at the time, live with it for awhile - this is the only way.

Is this the consensus?
Oh - just a note regarding "night and day"...

People who use these words to describe changes in the sound of their system might have experienced it on both ends: a system that delivers "transistor radio" music vs one that is conveying the nuanced differences between instruments, sound decays, atmosphere, etc..

Perhaps people who cannot relate did not experience both: either their system is always perfect (perfect AC, top gear, perfect room isolation) or they never got to the next step?

I'm just saying.
It is a personal experience. However, if we call "zero" the level where there is some loud music coming out of the speakers and "hundred" the live, unamplified symphony orchestra or chamber group then we have a lot of dynamic range to assign percentages.

However, I'm not that subtle myself. I can only distinguish binary (e.g "night and day") between listening for the umpteenth time to a program that I already know by heart (night), and hearing it again in a better way (well... "day"). Yes, after many enjoyable additional listens post-upgrade, the previous "day" might slowly turn into dusk... and that's when the itch needs scratching again.
A bit further on the dynamic ranges... for some of us perhaps "zero" is the current level of the system - whatever that is - and "hundred" would be the live unamplified performance etc..

In one previous post (Brownsfan), going from 98.3% to 99.2% might seem like a petty sub-1% improvement, but if his 98.3% is his "zero" then the improvement is a whooping 52% on the way to perfection.
... and conversely, if my system is at 60% (my "zero"), Brownsfan improvement of 0.9% (a petty 2.3% in my frame of reference) would make no financial sense to me whatsoever. I'd have to take my system to 80% to perceive the same audible benefit he's getting from his upgrade.

(taking Brownsfan's example as an example, of course).
I rather suspect habitual use of recreational drugs (legal for public consumption in the streets of Amsterdam). Seems more consistent with the story of a successful, inherently good character who always wins against the big bad world. Just because he's different. An 007 of the audio.
Hi Bo,

I must admit: I now enjoy your answers much less. You're actually only a braggart, aren't you?

Thanks anyway.
