Directional speaker cables - switching direction


Some time ago I started a thread regarding speaker wire directionality and my inability to understand how it could have any affect on sound quality. The question was inspired by the fact that, after quite a few years using them with my Martin Logan Odysseys, I discovered that the cables (Straightwire Octave 2) had arrows printed on them. Not surprisingly the opinions expressed were pretty strong on both sides of the argument but those supporting directionality were the most vociferous and in greater numbers, one to the point of being downright insulting. In no case, though, was an explanation given by those supporting the importance of cable direction for how this phenomenon occurs except that it should be obvious that when a cable is broken in in one direction only someone with an uneducated ear would be unable to discern the difference.

Even though I still don't get it I'm not taking the position that there is no validity to the directional claim; if there truly is I just don't understand how. This leads me to my two part question. I haven't been using the Octaves for a few years but now, because of cable length issues, I want to put them back in my system partly to avoid the cost of new quality cables.

IF, then, the directionality theory IS valid and I don't recall which way the arrows originally pointed or which direction they were "broken in" do those in support of directionality think I should install them with the arrows pointing toward the speakers

well, well, just yesterday, after setting my system back up friday night, and re- breaking in my speaker cables and speaker cable jumpers that are state of the art, I could hear a small difference in my right speaker compaired to the left, now friday night I was drinking heavy, celebration of 2 years and 8 months of dealing with my amp came to a wonderful close, so hell yea, I am going to drink!, back to yesterday, I was sober, after hearing a difference in the sound, I walked up to both speakers and evaluated the connection's, whoa and behold, only one jumper on the right channel, the negative was turned the wrong direction, instead of the signal going from bottom post to top, it was backwards, shut down everything, flipped the Tara Labs Omega Jumper correctly, bam, the wife says, what did you do now, I said why, she said that the sound now had fuller vocals and way more detail!, that said, over a year ago, we tested all the jumpers at the same time going the other direction, when we did that, I remember the wife thought then that something blew up because the sound was hugely poor, a much more difference then just one jumper out of place., cheers.
Hi Geoffkait, my wife has proven many times that she does hear better than me, her ears are more sensative to high frequencys, during most auditions of any new equipment, doing a/b testing, just when I thought my decision was done, I would go back to what she said in the very beginning of the testing, as it turns out, the one she picked is the winner, and then I'm like Damn, she is always right!, last time I checked my hearing at the doctor's, there was nothing wrong, yes, I can go with women hear better than men, absolutely.
Your correct Wolf_Garcia, my ear is more trained than her's, you know how it is, I am impressed that she like's the high-end, also, you should know, she is a very good musician and top flight singer that would impress many, that would explain that she really has an ear that is more trained than most audiophile's to say the least.
wolf_Garcia, I thought the same as you, now, I have a different perspective, looking at the over load of product's in Stereophile, The Absolute sound, and here on Audiogon, I think the High-end audio industry compaired to the late 90's is hugely live and well.
I assure you that when I reverse my directional Tara labs Omega Top of the line Jumpers that go from my bottom post to top post of my bi-amp speakers, the difference is in NO WAY SUBTLE!, likly, it is the way the speakers are designed?, I do know for a fact the the conductor out lay in these jumpers are specific going to one direction, I can see that looking at the jumpers with my own eyes, if you have cables that sound the same that are directional, get rid of them please, they are inferrior cables!
can you imagine what would happen If tara labs claim's was false?, I do not believe they would base their entire company on the claim of 8-nines mono crystal, super annealing process and not be what they claim, ha, ha,he,he, Im sorry, I got a good laugh out of that.
Awsome Jea48, very well done indeed, that was one of the best post of revelance that I have seen in a long time, are you a electrical engineer?
It is possible, and it has been done!, a cable dielectric and conductor outlay can and will and does direct a signal a particular direction, if the cable is well made, not some cable that is directional but inferior, there is alot of those out there, the difference in sound as said before is not subtle, it is huge!, when I change the direction of my Tara Labs Omega 10 inch jumpers, you can stand out side my house and hear the differnce if I flip the jumpers, very drastic I must say, I am not an engineer, do not ask me to proof it other than come and listen for your self.
I have read all the recent post here, one explaination stands out to be the best of why some cables are truly directional, so here is why my Tara Labs Omega Jumper's are directional,,,Another industry first is TARA Labs' propriety annealing process, known as SA-OF8N 99.999999% copper (super-annealed, oxygen-free, eight nines pure copper). This creates a unique, long, unbroken crystal structure called “mono-crystal”.
Scvan, all Tara Labs cables are hand made in the u.s.a., years ago, Tara Labs did make some cables in china, they got into alot of trouble with saying that they were made in the u.s. and was not, now that was only the lower tier cables when all that happened, that said, I asure you, all Tara cables are hand made in the u.s., and the answer to your question, since I personally know and speak to Matthew Bond, The engineering department is in Australia where Matthew lives, there is a whole team that works with him engineering, Tara Labs also has the purest copper in the industry, 8-nines, occ copper is 6-nines, both are mono crystal copper, absolutley there is a sound difference between the two, I have owned them both, Tara Labs use to use occ copper before they started extruding their own copper, manufacturing is done in Ashland, OR.
Thankyou jea48 for the microscoptic images of mono crystal copper, and the proof of the differences that is analized that you provided by the link called-images.
Hi scvan, check out the inductance and capacitance of the Tara Labs Grand Master Evolution cables, should come as a shock to you, since you like specs.
Great Post Jea48, the more I read what you have to say, the more I respect you, I enjoy your post, cheers.
