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.

^^^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.
The easy thing is that you can hear what is there and what is missing. That is Always clear and Obvious. Even if you do not know the equipment.

The first time I listend to clasical music in real I was stunned by the intimate sound of it. The voice of a female singer was very small and direct. With my eyes closed I used 2 fingers to make a proportion of her voice. That evening I changed the place were I sat. But the intimate sound of her voice stayed the same.

These days an intimate image and realistic proportion of instruments and voices are Always in every single set I sell or adapt. When voices and instruments become bigger the emotion is less involving. When I let people compare an intimate stage with a stage were instruments and voices are too big ( many f... idiots at shows do it. When I ask them how big you think an instrument or voice is in real? They say; we don't know) people prefer the intimate and reaistic image. Because the music pulls you into it. When the image is bigger the distance between you and the music gets bigger. And there is less emotion.

The other important part what influence our emotion in music is how deep the freq. response of an audio system goes. When it goes deeper there will be more emotion. I demo this by using a subwoofer and switching between on and off.

I am a big fan of the class A sound of Pass Labs. Why because it can let you hear the tmebre of a voice or even instrument much easier. This part is also very important for how much emotion people feel when you play there beloved music.

When there is a deeper and wider stage, voices and instruments become more loose from eachother. When I do a changement with cables and people hear it they often give a big smile. I Always say: smiles on people there faces and tapping with there feet during a show gives a good impression what they think about your demo.

The art of sound is what can make a system play emotion and give a sound to die for.

These days I can get a good endresult with Pro roomcorrection even in the worst rooms on this planet.

I Always try to find solutions for limitations in sound. I don't take no for an answer
