Thought I'd post this before they sell out again, got em the last time, handy since I don't have an fm transmitter and helps with extensions, etc…
Note these do not have gold plated tips, but 89c with free P/H more handy than not… ;)

To my understanding one of the following (or both)
- the malleability of the gold allows it form form better connections
- its corrosion resistant so I guess better connections for longer?
I've been told its not electrical conductivity
http://en.wikipedia.org/wiki/Electrical_resistivity_and_cond…
shows that it loses out to even copper.
I believe this stuff is only relevant to analogue connections. For digital cables a signal is a signal. If the cable aint broke, and theres a signal, doesnt matter what its made of
Gold is mainly used for its corrosion resistance, but other factors come into play.
Electrical contacts, whether in a switch, a relay or a connector have to conduct an electrical signal without changing that signal. A layer of oxide on the contacts will cause resistance, which is a particular problem with low-voltage signals, as contact resistance is non-linear and can cause noticeable distortion of low-voltage signals like audio signals.
Gold doesn't oxidize, so it it a pretty good contact material for low-power (e.g. audio) contacts. Unfortunately it melts easily, so if you use it for high power, you run a high risk of contact arcing causing the contacts to weld together. Silver-nickel contacts are commonly used in relays for this reason, that material has a low chance of contact welding.
Mercury-wetted contacts are even better than gold, but as mercury vapour is toxic, you will only find mercury-wetted contacts in sealed devices, e.g relays. Even so, mercury-wetted contacts are rare, and only used for very demanding applications.
Wow, thanks Professor, nice answer!
Nope, sorry to say you're both wrong…the real reason for the gold?
Check my bling bling, yo'!
wow.. that'll teach me a lesson on venturing out of my depth.
Some serious knowledge bombs being dropped here.
Thanks for that, I know i learnt something.
Every time I jump on Ozbargain I think to myself that the community is getting dumber and dumber. Thank god we have people like you, Russ - to balance things out :)
The point is to get you to part with 150% more cash than the next cheapest offering from another competitor.

Thanks OP, these are always handy to have around
$1.99 now ?
"Apply coupon code MLCK416PNL1 at checkout to receive $1.10 off item."
Nice one. Just what I needed. Thanks OP
Fantastic, another useful cable to have lying around. GF won't be happy but I am! Thanks OP
just ordered a corset from the lingerie deal to keep her smiling… the things we do.
really?! to keep "her" happy???!! LOL
Just out of interest, what is it that people are using that much cable for?
htpc?
Cheers OP. Tried to buy the two pack one and applied the code to save even more, won't accept it. Haha, it's so slow it's been ozbargain-ed again. Lol..
Basically only useful for AUX input but still… it's 99c.
I've used it in line in/out splitters and extension as well, PLENTY of uses…. ;)
is the coupon expired?
Coupon has expired
checked out as 0.89 but my netbank shows 2 seperate transactions from paypal. One for 0.89 and one for 0.97
both from meritline
At current price its still cheap at $2, already have a 2metre spare one so didn't get one but these are always handy for HTPCs, plugging ipods into amps etc. Even have a small one at work I use to input music into my notebook from my ipod as my ipod internal speaker isn't that good.
Wish the stock didn't go so quickly!
Bought, Thanks!
Anyway what's the point of gold plated tips?
