I don't believe in ultra-quality cables, and seeing some made with gold,
men ! that's a real joke !
To be clear : cable is cable, it's just a piece of metal.( Some people
claims they can hear the difference between a gold and a copper cable,
come on, let's be serious)
BUT cables are build in a certain way, it looks like people are messing
a lot, here around.
there are different cable types :
- coaxial cables are shielded which makes them noise protected
- twisted pairs are used when the signal is balanced (balancing signal
is a way to protect from noise) when not balanced, this cable type is
highly noise sensitive.
Cables also have impedance which is extremely important in high
frequency range.
- video cables are 75 ohms (coaxial type)
- phones (and network) cables are 100 ohms (mostly twisted pair types)
- audio cables have no impedance ( theorie : 0 ohms) because they carry
low frequencies signals (coaxial type)
Messing with cable impedance will result in signal loss.
Messing with cable type will result in noise gain.
When in audio range, the less impedance, the better. So theoretically
gold is better than any other metals.
But, actually the audio input impedance of every apparels is so high that :
- there's no real relevant signal loss.
- it must be well shielded (coaxial) because there's an "antenna effect"
when connected to a high impedance input.
Conclusion is to use the correct cable type and impedance, use quality
cables, but don't go buying gold when it works as good with normal ones.

however regardless of your rant, UTP carries a better signal. Thats why
we use it in networking instead of coax, in networks we grew out of coax

I wouldn't dream of disputing that. I also think it's entirely
irrelevant for the kind of signal that's sent over a typical home
theater cable.
