So, in precision voltage / current / resistance measurements we often use cleaned copper-copper junctions or copper-gold junctions to minimize thermal EMFs. That said, in audio applications, if the contributed thermal EMF was 100uV, if the full scale signal is 15 volts, that's only 6.6ppm (parts per million). That's nearly -120dB.

Because someone thinks it is a good idea. This may only be as a sales gimmick, because gold has long beena “mark of quality”. Or it may be thought to serve some useful function. Returning to optical connectors: gold plating makes no difference to the light in the fibre or to the interface, at least initially.

Gold isn’t as conductive as silver or copper, and due to its cost, it’s never used as a primary conductor. Instead, gold is often used as a coating on cable connector ends, which we will cover below. Aluminum has much lower conductivity and is typically found in the most inexpensive audio cables, which lack the same clarity and brightness of sound.
