Right, but the impedance is fairly flat across the spectrum, so cable resistance problems aren't going to be so serious. When cables start influencing sound is when you have very long cabling (as in a lot of SR applications) or when you have bizarre speaker loads that aren't linear. They definitely sounded _different_ than conventional stranded cable... but after a little listening, it was clear that they were not better but actually worse. Don't those have capacitors in one end, & are intended to be aimed in the direction of signal flow? They have some kind of lumped sum stuff on each end of the cable, in metal boxes. I don't know what was inside them because he had the cables on evaluation and was reluctant to let me try and pry them open with my pocket knife. But whatever is in there, I don't think it is a good thing, on his system anyway. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

If you were going 1 mile, then the skin effect may be noticeable, but a mile of wire has other problems with DC resistance, capacitance, and inductance as well. Transmission line considerations need to be invoked at those lengths. David |

But what's also true is that while you can make good gear sound bad with really poor cabling, there isn't much difference between really good cable and pretty good cable as long as you understand what makes cable good for a particular application. This is something that's not apparent to some makers of voodoo cable. |

You are misquoting the ad. The folks at Monster claimed that low
frequencies were affected by the amount of copper in the cable cross-section, while high frequencies were affected by the surface area, thus their "thick but fine" cable, high mass combined with high surface area. I went from zip cord to monster cable at the time and could definitely hear a difference, especially in the bass. |

Stranded wire of a given cross-section behaves *exactly* like solid core of the same gauge from the perspective of 'skin effect'. There is only a difference if 'litz construction' is used where every single strand is insulated from its neighbours. thus their "thick but fine" cable, high mass combined with high surface area. I went from zip cord to monster cable at the time and could definitely hear a difference, especially in the bass. That'll be because the 'monster' cable was a larger gauge of course.

In any stranded wire, skin effect is only affected if the individual strands are insulated from each other - as in Litz construction. Non-individually-insulated ( i.e non-Litz ) stranded wire has the same skin effect as solid wire of the same gauge. Graham |

So, skin depth is possibly a factor @ 20 KHz ( do please Google to get the exact equation ). The big story is that ordinary stranded wire is no better than solid as regards skin effect. Every conductor has to be individually insulated ( litz wire ) for skin effect to be absent. Graham |

I went from zip cord to monster cable at the time and could definitely hear a difference, especially in the bass. It's regrettably *all* bad science. The whole post. If just surface area was the determining factor, then a bundle of finely-stranded wire would measure and sound just like a piece of thin-walled tubing. In fact the bundle of finely-stranded wire measures and sounds just about like a piece of solid wire with with the same amount of copper per foot. The piece of tubing with the same surface area will measure vastly different, but since skin effect isn't an issue for practical wires in home stereos, it doesn't effect the sound. For years, Monster proudly sold separately-insulated stranded wire as some kind of a solution for skin effect. They happily took the vast markups to the bank. Fact is, that cable measured not much different from regular speaker wire with the same sized conductors and spacing. Then Monster figured out that the real way to do something about skin effect was to make foam-core wires that were a lot more like hollow tubes. Even though skin effect is a non-issue in the real world, they still happily took the vast markups to the bank. Any perceptions you may have of an audible difference were no doubt due to the fact that your experiment was not level-matched, time-synched, and bias-controlled. |

Stranded wire of a given cross-section behaves *exactly* like solid core of the same gauge from the perspective of 'skin effect'. There is only a difference if 'litz construction' is used where every single strand is insulated from its neighbours. Hate to be pedantic again Graham, but that's not quite right. As I mentioned in another post, Monster made a stranded cable where every strand was insulated (fiber thread over enamel for each strand). I got a set of the old anti-skin-effect Monster cables from a friend and found that they measured almost exactly like solid or stranded. In the process I confirmed again what you posted above about solid and stranded not making much of an electrical difference. Later on I read up on the matter in the Scott's Guide http://www.st-andrews.ac.uk/~www_pa/...o/electron.htm To cut to the chase, skin effect is based on magnetic fields, which cut through thin layers of insulating materials with the alacrity of a scared fawn. No, in order to address skin effect you need to make some gross changes in eable geometry. Electrically hollow conductors are used by people who are serious about skin effect. The hollow conductors may be stealthy, such as the silver-coated aluminium and copper-plated steel cables that the cable guys use. Yeah, its solid metal wire, but there are big differences in the conductivity of the metals that are used. Monster now sells an anti-skin effect cable with a foam core, if memory serves. Silver-plated Aluminum foil wrapped around a foam core should be the ticket, if you're having bad dreams about skin effect. Trouble is, many of the approaches to reducing skin effect end up increasing inductance. Inductance can be the larger problem with speaker cables. |

But, the skin is very deep. (And in fact, the notion of the 'skin' being an abrupt transition is false because the current basically drops off steadily and lograrithmically as you go down the depth of the conductor). It's true that skin effect isn't a big deal at audio frequencies, but I could figure some places here and there where it might be. It's certainly measureable at 20 KHz with an 8 ga conductor even if it's not a big deal. I did all the math in an article in Positive Feedback back in 1996 some time that may be worth looking up. Or you can get it from the ITT Radio Engineer's Handbook where I got it and so the plugging and chugging yourself. -s-cott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

A thin film of silver deposited on glass is an excellent conductor at microwave frequencies." http://en.wikipedia.org/wiki/Skin_effect At low frequencies, any concern about conductor resistance can be resolved by simply using a larger conductor. Concerns about "skin-effect" at high audio frequencies are pure snake oil when used by botique cable vendors. I suspect that the requirements of most of us for our sound reproduction/reinforcement systems are significantly more modest than those of the nearest power plant. |

I have to agree that for long runs bigger is almost always better. But
I have to admit that like Scott I too have noticed a slight difference between stranded and solid wire. I have no idea why and I long suspected it's purely psychological. As Pooh says, the main advantage of stranded is the flexibility. In a permanent installation anything goes. On a lark I once used copper WATER PIPE for such an installation. Worked positively great! Yeah, I've heard all that low oxygen BS but I don't think it matters. Just going up a gauge does way more than than any stranded-solid difference. If you need flexible, as someone said jumper cables work very nicely. Also I once made a bunch of speaker wires out of heavy braid shoved down tygon tube. (Got a huge roll of braid free!) Those sounded great and looked cool too. 12 Gauge power tool extension cords work great and can be scored cheap (look for two wire rather than 3 wire type). For in-wall I'd go with any kind of standard solid house wire. Lowes or Home Depot has a nice selection at reasonable cost. If you want on floor wire, I'd go with the heaviest gauge you can buy at the local pro audio supply shop. They usually have really nice rubber covered speaker wire that looks nice, wears well, is nice and flexible and doesn't cost too much. Often you can find it in the range of 16 - 10 gauge. But I wouldn't spend the extra cash for flexibility for an in-wall job. Basically it's all about Ohms. Low ohms means the amplifier can keep a tighter damping factor on the speakers. So don't scrimp on connectors either. No sense using 3 inch water pipe for wire and then using some connector that develops 5 Ohms after a year of service. Benj |

I think your heart is in the right place, but your terminology seems to be out-of date. Low series ohm speaker cable means that a good amplifier/speaker cable combination can provide the speaker with a low impedance source, which is what the speaker was no doubt designed for. However there is a point of diminishing returns. The speaker itself contains a relatively large resistor in the form of the resistance of the voice coil. So beyond a certain point, adding copper to the speaker cable is yet another waste of time and money. |

It's not even a bet, you just prove your point and collect the prize! **FIVE GRAND!!! Where can I get me some of that? I reckon I can hear the difference between two speaker cables (of my choosing) with the following equipment: Cable 1: Goertz MI-1 Cable 2: Naim speaker cable Cable length to be 20 Metres These are the speakers I choose to use: www.rageaudio.com.au/accu.jpg Can I put you down for a few Squid? -- Trevor Wilson www.rageaudio.com.au |

"Arny Krueger" wrote in message ... wrote in message ups.com... Basically it's all about Ohms. To a point. Low ohms means the amplifier can keep a tighter damping factor on the speakers. I think your heart is in the right place, but your terminology seems to be out-of date. Low series ohm speaker cable means that a good amplifier/speaker cable combination can provide the speaker with a low impedance source, which is what the speaker was no doubt designed for. However there is a point of diminishing returns. The speaker itself contains a relatively large resistor in the form of the resistance of the voice coil. So beyond a certain point, adding copper to the speaker cable is yet another waste of time and money. Right. The concept of damping factor means that the impedance of the source should be considerably lower than the resistance of the speaker. If it has validity (and it probably does), that explains why people notice cables with a resistance of maybe 0.5 ohm, even though the actual attenuation into an 8-ohm speaker is very small. But there are still diminishing returns. I doubt anyone could tell the difference between 0.1 ohm and 0.01 ohm of cable resistance. |

Unless they had a speaker like the Apogee Scintilla which drops below 1 ohm at some frequencies. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
