Where I've always seen the issues is not with the cable itself, but the crummy solder joints some mic cables come with. I used to swear by ProCo cables (it's a Michigan company and when I can I like to buy local - I'm a Michigan native), but we had a batch that had some less-than-pro solder joints that I had to re-solder to bring back to life.

If you can expose the solder connections before buying, do so. To me, that's where most of the quality issues come into play.
