Interconnects, some have directional indicators, why?

"Geoff, above and in many discussions you have stated that the wire drawing process impacts the wire crystal structure making it inherently directional.

Assuming it does, I think the question is does this impacted crystal structure in some way make an audible sound difference when the wire is inserted into a system in one direction or the other?"

imo the answer is yes. whether the wire is the wire in a cable, in a transformer, wire in a fuse or capacitor or in the internal wiring in electronics or speaker. Thus when you reverse unshielded interconnects that are in all outward appearances symmetrical you should notice the sound change for the better or worse, depending on whetyer they were connected in the correct direction to begin with or not.

jetter also wrote,

"One might think that in order for it to make a difference, the signal, power, whatever, would need to flow differently depending on the direction of the crystal structure. This would imply that if the wire was inserted incorrectly from a directionality viewpoint, the crystals are impeding, or in my obviously non scientific terms ,snagging and impeding the signal or power compared to the correct direction and this somehow impacts the sound."

That’s right, imo. The wire is phyically asymmetrical, like the quills on the back of a porcupine. i would say this asymmetry causes distortion of the audio signal, even if the wire (fuse) is located where the power cord comes into the amplifier, even if the wire is located in an AC circuit. it is audible and measurable.

Jim, electromagnetic field would be contained in conduit or even braid.  Very often explanation of Poynting Field brings example of coaxial cable, showing that whole energy flows thru dielectric between the wire and the shield.  As for Boulder 3060 amp - I don't know.  Perhaps somebody else?  Al?

Kijanki, thanks for the good comments about the Poynting Vector etc.

Jim, wow, the Boulder 3060 is certainly quite a monster -- 441 pounds including its 86 pound granite base, a price well north of $100K, and 6000 watts max power draw. Given the latter, it is of course designed for use with 240VAC, not 120.

Regarding your question, I doubt that anyone could provide more than a wild guess. Partly because the effects on the AC waveform of the 8 foot run you described wouldn’t seem to have a great deal of predictability, partly because those effects would seem likely to be less significant than variations in AC waveform characteristics and voltages among different locations, and partly because we don’t have detailed knowledge of the internal design of the amp. And even if we did have detailed knowledge of the amp’s design it seems quite conceivable to me that extensive tests and measurements would have to be run to pin down the specific sonic character of whatever effects might result, if any.

Kijanki,

Thanks for the response.
I had already read about the Poynting vector  after you posted about it on another thread last week. I supplied the link for others reading your previous post.

Al, (almarg),

Thanks for your response. I missed the line voltage for the amp is 240V. I went back and reread the post and sure enough the OP said it was 240V for the new amp as well.

Here is the thread. scroll down to bflowers first post on the thread.

If you would please post your thoughts on the thread.
