Always amuses the hell out of me when people refer to it as oxidisation
Well whatever, you know what I mean.
Current Lash Up:
TEAC VRDS 701T > Sony TAE1000ESD > Krell KSA50S > JM Labs Focal Electra 926.
Why?
Taken from Wikipedia (my emphasis):
Copper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brown-black copper oxide which, unlike the rust that forms on iron in moist air, protects the underlying metal from further corrosion (passivation). A green layer of verdigris (copper carbonate) can often be seen on old copper structures, such as the roofing of many older buildings and the Statue of Liberty. Copper tarnishes when exposed to some sulfur compounds, with which it reacts to form various copper sulfides.

I have seen stereo systems set up for decades that just get dusted once and a while using AC zip cord with no ill effects , Cars are a different story , they are exposed to massive amounts of moisture and extreme temperature changes. I have seen cheap clear speaker wire turn green inside and in boats actually corrode away till it fails.
If you are having this problem in your home a dehumidifier is clearly needed.
This is the best stuff I have ever seen for resisting moisture and it really resists micro phonics on hard surfaces or in noisy RF environments. It is directional so look for the small arrows. Audison Connexion cable.

My understanding is that metal corrosion is driven by electrochemical processes and are greatest with a greater difference between the metals. Could it be that the end of the cables that corroded quickly had different metal types (copper cable, gold connector for example) where as the ends that didn't corrode had metals that were not so dissimilar (copper cable, copper alloy connector ?)

That is actually called disimaler metals corosion.
There is also such a thing as inerrgranular corosion .
The oxidisatation he is experiencing is most likely caused by humidity.I am not saying electrochemistry is not playing a roll here , but it is not the largest factor. At the rate he is experiencing moisture would be my first suspect. For copper to oxidize in just a few days his house must be like Vietnam in summer.
Even under electalisys it takes months for disimaler metals to interact to the point he is talking about.
Spray your connections with deoxit if the problem continues and move on with your life.
