This has been my experience too. I use some quality contact spray (on both the plug and receptacle) routinely and it generally keeps the problems at bay for quite a while. I believe I also bought some Planet Waves cables (which seem well made) and have even replaced the contacts in the GK units with gold-plated versions. Good contact spray, and frequent cleaning, is essential from my experience.

giving the connections a good cleaning has taken care of that on my cables.
