I only use cables produced for the professional market such as those made by Belden and Canare. The consumer stuff made by Monster and others in this class is just too iff-y in quality and reliablility in my opinion - even the ones that cost a fortune. Most of these are made offshore by gawd-knows-who-in-who-knows-what-country.

I have never encountered a professional cable that exhibited any tendency to oxidize or otherwise change over time. Professional cables are also very inexpensive since, well, it just does not cost a lot to make wire of high quality - and they charge accordingly with no "hype markup".
