CJ, which way do you think the current flows in your speaker cables?
You have dismissed things like alternating current as 'techno-babble' and pseudo-science so i'd be interested in how you think it works.

I am just sitting here listening after replacing my Chord Carnival speaker cables with Auduoquest flx - slip 14/4 cables and I am wondering if I wasted time and money.The difference is sounding quite good in favour of the Audioquest.but time will tell.I am listening to Vinyl and digital trying to convince myself that there is a difference

I felt there was a difference having changed from Carnival to FLX, but I think it's how I wired it up more than anything.

Chebby, you should no more than most, 'technical' is often simply the starting pont in hifi, a referance, when you sit down and listen it dont always come out the way the figures sugested? I am not going to fall into the trap, expanations are not always possible to satisfy the techno and ps-science minded. As I have said before, and you have told me! . . . sit down do some serious listening, weight up the pros and cons, decide what you like and enjoy . . . I dont have to know how it works. I know how it sounds before and after a change or adjustment . . . that all I need to know.
My Carnival was wired simple single wired.
The FLX I wired up with 4 banana plugs at the speaker end.
i have searched high and low on the net, and not a single piece of real research into the directional aspects of cable. Most posts refer back to Naim, or to crackpot cable manufacturers who clearly have an axe to grind.
As Naim have (apparently) conducted tests on this, I will send them a note to enquire about their research.
Anyone suggest an email address?
I received a reply from Naim, which I will ask their permission to post. In essence, there is no explanation of the effect or why this makes a cable carrying AC directional, just that it is due to the extrusion process.
I did stumble across some analysis that talked about the formation of micro diodes at grain boundaries, but I have lost the link, and I can't seem to find it again (and I didn't think much of the analysis either).
If there is an effect, it will be measurable. It is actually quite tricky to measure very low resistance, with a standard multi meter the resistance of the test leads and croc clips becomes a significant part of the measurement. There is a technique using 4 test leads that gets over this, but I dont have a '4T' meter. I am on the look out, and as soon as I get one, I will post the results (I do have some lengths of NAC A5 and A4 cable - but thats another story).
If this is of interest, I could have a go at measuing the LCR parameters of other speaker cables. I had planned to have a go at this some time ago and then posting the results, but work got in the way.
Well. I have gone back to my Chords I find that they do infact sound better strange really saying that speaker cables dont make any difference.The Audioquest played the music quite different to what I am used to the sound was different instruments sounded different the whole soundstage was different to the degree that it didn`t sound right to me.I am day off today so I have bags of time to swap and change.I only played one vinyl album to listen I found the Audioquest very boomy in the bass dept so I changed one cable back to the Chord and there was an immediate change I then changed the other and I am back to the sound I prefer its possibly just my equipment.I had a bad shopping weekend last week I use a QED u-play puck to stream my music from the pc to my stereo I went to Richersound and bought the new U-play plus which allows you to use your own interconnect and I thought there is going to be an improvement there I set it up and its back in the box to be returned because it didnt sound as good as the original.So I think the moral of the story is leave well alone what works !
I received a reply from Naim, which I will ask their permission to post.
You only have to search for 'directionality' on the Naim user forum to find Naim's response (from site admin and Naim employee Richard Dane)...
"...Fact is, on interconnect and Burndy cables in particular, we don't rely on the cable factory to tell us the "direction" - just because the printing goes in a certain direction doesn't mean that the insulation has been applied consistently in the same direction from one reel to the next. That is why the only true test is to listen. Roy gets some samples cut from each reel and listens to them before declaring the direction. He says it's usually quite easy to tell...Speaker cables can be problematic because if they are printed incorrectly then the cable must be scrapped - not cheap and very inconvenient! They are sampled by batch, and luckily mistakes are rare..."
"Anybody who has been to visit the factory and had a peek into his office will usually see a load of cables there - usually the last batch that were cut to length, made-up, and then listened to. What can I say, it's not about measurements, it's purely subjective, and mainly down to obtaining the maximum consistency throughout Naim product performance. It's a philosophy that extends right through everything that Naim does. I've listened to cables one way and then another, and the sound is different. Heaven knows why, but that's what I hear. Sometimes it's obvious, sometimes quite subtle. It's best done on a system and a piece of music that is very familiar. Personally, I happen to trust Roy and what he hears. Why would you trust Naim to listen to and select components for the way they sound and not trust that we also listen to cables? Now if the question is WHY do cables sound different one way to the other, then that's something quite different and I'm not sure anybody has a completely satisfactory answer to that."
1) They have a bloke called 'Roy' who samples all the cable batches by ear and then determines their directionality.
2) It's not a technical measurement but a matter of trust in Naim (well, Roy actually.)
3) They have no explanation and are not aware of anyone else having a satisfactory explanation for the phenomena.
The quotes I pasted were from 4 years ago so I would like to see Naim's reply to you.
Well if anything happens to Roy we're all doomed.

I don't think anyone's saying that in this thread. The 'dispute' is whether speaker cables sound different depending on which end you put to the speaker. Because if they do, then some characteristic about them must be measurably different depending on which way you turn them, and that property would already be known and acknowledged by scientific evidence.
It's a bizarre belief which conveniently ignores the fact that in any case the output from an amp is AC, despite the little arrows on some speaker cables commanding it not to be. So even if a speaker cable was even a teeny weeny bit directional because of 'micro-diodes', it still would make slightly less than sod-all difference.

Listen to any track on the same equipment and it will sound different on different days. Heck, listen to the same track twice in row amd you'll able to hear something different if you listen hard enough and actively listen for changes.
Another strang phenomenon . . . 'I believe the world is round' . . . They could not prove that either untill some sailed around, to demonstrate 'the fact'.
Day to day yes it happens, especialy the time of day, but the same track twice . . . nah . . . I would say you are pushing te boundaries of credibuility!
So, have you tried the link I posted, were your ears fooled?
