If you doubt about buying more expensive cables, i'd have to tell that this is super worth it. This one is not that expensive and will hold for million years.
Your system is only as good as your worst part of it. I had some problems with the cheapest sssnake cables, so I found this the hard way. I would never stress myself with the reliability of this cable though. So if you got some more expensive PA, you might as well think about more expensive cables.
