I'm just wondering, has anyone ever made any measurements of cable performance? I mean, if there is difference between two cables, then this should eventually result in a change of the electricity going through the speakers. Although I am not at all experienced in hifi-measurements, isn't it possible to connect some kind of measuring equipment in parallel to a speaker and construct a plot of voltage vs time. This graph of the same musical passage should look noteably different for two different cables if there is any difference between them. Correct me if I'm wrong in anything here.
By the way, I am a semi-believer. I have a roughly 1500$ system all in all, including speakers, and bought an RCA-cable for approx 100$ and did a comparison between that one and RCA-cables that are practically free, and my main noted difference, objective or not, was the balance between overtones in e.g. piano music, with the more expensive cable the piano did sound more warm and lively.

Really for the most part I think there is a ton of misinformation out there. BUT imho it can not be overemphasized enough that in a multichannel system the channels should be as electrically matched as possible. The speakers for all intents and purposes MUST be identical twins. Ideally the loudspeakers (with the aid of a phase linear offsett of the crossover) should be able to cancel an inverted square wave from the other opposing speaker.
If good is good enough, don't mind.
There are more to it than power loss but even ignoring that, put an active load on the other end of the cable and do the calculations again.
Thanks, but some days I do misread things. "I" of course is not what amplifiers provide it is V with an I limit. It is the power loss in the cable but not the total since the amplifier is modeled as a constant voltage device so the total load impedance goes up thus a greater loss of power than normally assumed and often wrong in many available tables.
Im wondering why you even questioned him considering you might lose the sale.
There is a difference in selling products to people that want them and telling a customer that walks in that those expensive cables will improve their system to a point where they will have orgasims instantly....subjectively speaking
Im all for people buying what they want, spending money is a great thing for any ecomony. Subjective exaggerations is what need to checked at the door since most people can be convinced of almost anything.
Yes, I posted measurements and simulations earlier in the thread for a common 18 gauge recommended maximum length.
The manufactures must be handing out some really crappy cable with the surround sound systems for it to be such a huge concern. I thought we were talking about sufficient cable as compared to $1200.00 a pair cable.
I can see your point with surround sound with all that's going on.

Speaker cable and coaxial signal cable are too different animals. Coaxial cable has different properties.
Only to point out that there are sales men and sales men.Generalizing sales men as I think Markus did,might imply that all sales men are a disease,or perhaps I would be a better sales man(even person)and meet Markus's standards,if I let that sale lost.Am I in peace with myself?You bet I am.

Some of the larger co-ax cables can make very nice speaker cables!
Although they tend to be rather stiff.
Back to reality -
Yes, cables for HD video and multi-channel audio are an entirely different thing. The cable can make a huge difference. Take Ethernet for example. The cable can be the limiting aspect of performance. But audio signals are ssslllooooowww. Thats why you can digitize 7 of them into a single wire without too much trouble at all.

I'd love to see you prove me wrong
'Cmon, how can you live with yourself buying from diseased (shady?) folk everyday. The sales person may be many layers away from you amytime you buy bread, apples, icecream, interconnects.
How do these shoes feel sir? That's good, they match your belt too. What's diseased about that?
Anyway the idea that well a constructed cable of adequate gauge in plain clothes is somehow inferior to fancily dressed (or re-dressed) cable of the same guage is just dumb. A bit like the same guy (or girl) dressed for the weekend or dressed for work, still the same guy (or girl).
Here folks is my cable. I buy it in 100 meter rolls from an autoshop. It's black and thick and strong. It also sounds just fine.

Well I dunno what it is that makes me so sensitive to it but if something is even a little off on the left side of a good system and not the right side or vice versa it is really obvious to me. Really I don't think my actual hearing is even that good or should be able to detect something so small. But I've done it to myself a bunch of times with very small deviations that just drove me nuts. People will tell you it's the room, it's your ears etc.. Nope it's electrical.
It's not so much the degradation or anything audiophile like keeping the signal pure. You can distort the crap out of the signal as long as you distort it the same on both sides.
