I'm not entirely sure what the difference between the two are but I am curious if they'd be at all good for connecting my source (sansa clip+ (rockboxed)) to my amp (PA2V2). Thoughts?

Convenience is the only special quality these cables might have. If that suits your needs, then they're OK.

Yeah, they are convenient. But I mean, do they suck? Or are they of decent quality?
