Quick theoretical question here

I was wondering about this. The question is will it lower conductivity to the point that copper would be just as good since they are so close and golds conductivity is relatively higher by comparison?
Just asking as I dont know...

I had to break out the Physics book for this... //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Estimated:

3 Meters of Silver Cable, Pure:

4.7717*10^-8

3 Meters of Silver Cable w/ Gold .001 meter plated ends:

4.7817*10^-8

3 Meters of Copper Cable, Pure:

4.9923*10^-8

I am not physicist, but the difference between silver and copper seem minimal, at best. Could Joe Sixpack actually hear the difference?

Most likely not...

At that price level in cables it is a bit insane. I believe a good cable will get you where you want to be, but it is not sensible to go that far into the cable insanity.

Actually, the resistance isn't really all that important when it comes to this point.

Maybe over a 1,000,000 meters Silver would work better than copper, but whatever. Gold is just good to use because you know it will almost never disintegrate like copper and silver does.

I've got gold plated connectors on a lot of my connections and I still put dioxit, preservit, and Contact Plus on them periodically...

I was wondering how beneficial it would be to opt for the silver tinner HDMI cables. Looks like not worth the trouble.

Hey thanks. So there will be a measurable difference but chances are most likely not audible. That is what I was looking for.

As long as they are certified for the HDMI speed you are planning on running you should be good with out the silver ones.

Good luck finding a meter to measure that. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

There would certainly be more weaker links in the chain than 0.001m gold plated cable ends. Recording equipment probably couldn't even detect a difference. Check the inside of your speaker or your amp!

Indeed... Makes very little difference...

Why? //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif//content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif//content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Hypothetical simplified.

The output of you source is here -> Then it usually connects to a low

resistance resistor, lets say 50 ohms - 200 ohms.

The input of your amplifier may be 10,000 ohms - 50,000 ohms typical.

Put a cable in there to interface the source with amplifier

Source [50 - 500 ohm output impedance] -> your cable -> Amplifier [10,000 - 50,000 ohms input impedance]

Lets assume;

Source [50 - 500 ohm output impedance] -> cheap cable is 10 ohms -> Amplifier [10,000 - 50,000 ohms input impedance]

vs.

Source [50 - 500 ohm output impedance] -> superman cable is 0 ohms > Amplifier [10,000 - 50,000 ohms input impedance]

Compare the two scenarios. Follow the signal path.

The signal comes out and get 50 ohms - 200 of resistance, then flows thru

either zero ohms or 10 ohms of resistance, then enters the amp with 10,000 - 50,000 ohms of resistance.

Do you think that cable with zero or 10 ohms makes a difference? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

When you analyze cables in signal path, you analyze it from a 'low pass' filter

effect and since cheap cable already has low resistance, that isn't a variable

unless you run thousands of feet or more.

Read this, it's basic AC/DC electronic theory. Perhaps the first two classes

you take if you if you seek to understand electronics.
