And taken further, it means either two of the three never resulted in completed sales via this AVS forum, or, he sold all three via AVS, but two of the three just didn't bother to leave any feedback. Which isn't uncommon, if you've ever sold items before, whether it be on Ebay, Amazon, Audiogon or some other forum.

If our resident forum genius couldn't piece that together on his own, that must make me a SUPER genius!

That settles it. I'm going shopping for velvet-lined pocket protectors this afternoon. My diamond-encrusted protractor deserves the best.

Never bought or sold on any of those..never even looked before. If I needed to do that, I'd get one of my kids to show me how.

Waaaahh. I miss mine..

Been using a 12 inch digital angle rule I picked up from Klingspor's bout a year ago. The silly thing measures to .05 degrees.. Man, that's nuts.

Next will be an INCRA miter 1000HD.

This has the implication that two devices can measure exactly the same on the bench, but sound differently at the user's location.

So despite the fact that both devices have can have the same measured specifications far below what is considered to be human thresholds, actual useage could possibly present differences..

Hmmmm.

Back to the OP...

Does "directionality" matter with speaker wire?
The concise answer would be a new milestone.

No, speaker wires are not directional.

Why arrows?

The same reason we have arrows on the road for idiots to know which direction to go.

And you thought all electrons were created equally smart !

I do a lot of lamp repair and was searching cyberspace for references to corrosion in lamp cord when I came across these posts on this website. I frequently replace lamp cords that are corroded under the insulation along their entire length. This is almost always found on inexpenvive Chinese? "throw away" (cheaper to buy a new one than have it repaired) lamps. This corrosion is a HUGE problem since as the copper corrodes and is replaced by corrosion product there is less copper to conduct the current and overheating of the wire can occur resulting in failure or fire. I am thinking it must be due to sulfur in the insultion. Big, big problem!eek.gif

You see enough corrosion to cause wire heating to fire/failure? That's a lot of corrision... Not disagreeing, just surprised. Most of the time I have seen problems it's at the connections even if the wire is green up and down its entire length.

don, as usual, you are being kind... smile.gif

we live in the internet age... i am relatively confident that if "cheaply wired chinese lamps" (i.e. only 99.999999% of the lamps sold today rolleyes.gif ) were causing house fires, it wouldn't exactly be a well kept secret...

not to mention all those chinese made extension cords that would also be an issue...

I have seen surface coating on copper wire but never enough to reduce the gauge enough to matter. I don't think copper can do this, unlike steel or iron will.

Normally the corrosion stops once an initial layer has formed as it blocks O2 from reacting with the layer underneath. I think. Been decades since my inorganic chemistry classes.

Back in early 2000 I wired my prior home family room for 5.1 sound, running the 12/2 wired under the room via basement and then coming up at each speaker location.
All open space in the basement, no in-wall, just basic 12/2 wire.
I ran out of wire, went to local Lowes and they had a different supplier for the wire, it was 12/2 but thicker outer jacket, anyway I bought a 250ft spool of it.
IMG_4933.jpg ...IMG_4934.jpg

Fast forward, I used that in my new home family room home theater, and it did oxidize over the years. frown.gif
(I took these pictures back in Feb-2010)
IMG_4927.JPG...IMG_4937.JPG

IMG_4939.JPG

Guess what, the speaker still work fine, sound fine, and what not.

I've since used most - not all - of the remaining 12/2 wire on that spool for my outdoor HT set-up.
You can clearly see the "green" 12/2 vs the normal 12/2 - both bought circa 2000, hey gotta use it since I own it.
IMG_3823.JPG... Pre%2520show%2520set-up.jpg

I've since used the remaining 12/2 length of that "bad batch" to extend speaker wires as I relocated some in ceiling 2' x 2' tile speakers in my basement when I got a pool table just a few weeks back.
Just cleaned up the oxidization, soldered them to the existing 14/4 wire there (more leftover wire from the HT project), and it works fine.

I've had similar situations where the wire got ugly and green. I've seen it happen to cheap wire and expensive wire. The first time I saw it , this was a roll of upscale Monster Cable.

Clean the strands up with fine sandpaper and it gets bright as new, and solders and hooks up well. A good electrical connection is gas-tight and this tends to keep the problem from recurring where it counts.
