Sure. again if you are going to get into a meaningfull discussion on that subject, either base your arguments on electronics and physics principles, equations and laws/theories. Or on relevant instrument based measurments.
The usual scientific procedure is to describe what you think is happening using laws of physics, then double check that with measurements.

If you say something like *you think* then you need to say why?
BUt I dont want to get into another cable conversation... Go to the website I have posted..Read..Learn..Be enlightened. It has the equations and the measurements.

 

"bamboozle all you poor bastards without university level electrical engineering or physics" that is just offensive and is elitist at best. Your point does not give you the mental imperative to say that, nor does your post make your point. A simple desire to learn electricity at a vocational level is adequate.

POST WARNING: OFF TOPIC
for most cable designs the cost driver is the copper, period. There are numerous cable designs (and I am WAY off topic as this isnt DC power cable topic) that do cost a lot to make and if you dont sell hundreds of thousands of feet the 'bulk pricing' doesn't happen (my dealings with custom cable manufacturers bears this out). the use of silicone or expandable tapes for water block, the level of shielding or freq band of the shield, the low smoke zero halogen cable jackets (and the always popular cross linked polymers) add to the price but the copper still drives the buss most of the time. For that reason I give specialty cable manufacturers (still not talking audio cables yet) a break (to a point) on pricing. Usually the problematic cables involve low amperage signals (and usually analog) that have to deal with RFI or EMI issues. The solutions for RFI are meaningless for EMI usually. So not ALL of the high priced stuff is gouging alone, but if you need an odd ball cable made be ready to pay the price ("I need 20 feet made", "were sorry sir our minimum order is 1000 feet, we will be glad to cut the 1000 foot cable we will make to length for you"). Believe me I am very happy when I can buy Beldin or Tyco cable off the shelf.

Yet when I look at the prices of specialty audio cables it can be mind boggling (look at the Nordost valhalla's) I would rather have a car for that money. Even if it made a profound difference I cant justify the price of some cables.

 

I seem to be coming off a lot more negative than I mean to, I apologize to those I have been 'pinging' on vrdblu and zoomer come to mind... I am trying to stimulate discussion not an argument

 

Oh yes, that is what happens all the time on internet forums.

Then why are you posting in this thread, or on this forum for that matter? I suppose we're all a bunch of mouth breathers who need your insulting enlightenment. I don't remember reading anyone's post supporting the use of this cable design, so who are the "poor bastards"?

 

This discussion has made me curious. Zoomer, what cables do you use in your system, and why? Please do use such terms as inductance, capacitance.. wire diameter, wire spacing etc...

 

hm dunno yog

 

There is a good article on speaker wire at audioholics that basically concludes that common zip cord speaker wire is very good. They do cover inductance and capacitance and how it is affected by the wire diameter and spacing... Read it.

I am not suggesting that there are not differences in the quality of cables, and the materials used for example cheap insulation and connectors that get brittle, but what I am saying is that no many of the cable companies use completely bogus claims in order to differentiate their product. These claims sound plausible to untrained buyers.

Next time I am in Ottawa we could talk about it.. Beer is on me.

 

lol, but I would have to fly from BC to Ottawa.

I'm not trying to bait you or anything. See, in addition to bein an installer for the last 20 years, I do have "university level electrical engineering [and] physics". I don't need to wade through the propaganda on that site to understand capacitance, inductance, etc. I have been around and read around long enough to have seen most of the topics like skin effect, cable spacing, green CD markers, etc rise and fall. Some warrant consideration, most don't. Much of what they say on that site is certainly true but they have thier biases and preconceptions as well.

Anyway, my stance has always been that usually the extra money you pay for decent cabling has little to do with sound but more with better physical attributes that may make it easier to install or survive better in a car. And as with many things, the laws of dimishing returns applies here and the slope is particularly steep with cable..

 

A little off topic here, but just heard of Monster Cable RCAs being sold at Dollarama. Going to check it out this weekend and will post up results in a separate thread.

 

I must have misread who posted what from where.

nods and shakes hands. I think we agree on this one. !
Sorry for my edgy post.

Care to discuss the value of capacitors? LOL btw I have setup a simulation in spice with models for an alternator, battery, cables, 1F cap and an amp that has a pulsed 100amo load. It is interesting and does show that the cap suppplies current for a non trivial time but not sure if it has any effect on performance of the amp being that an amp is a voltage gain device that should be imune to fluctuation in the PS rails. The weakpoint is the difficulty in getting proper models of alternators/regulators.

Happy to chat with you about technical matters!
