I also own MIT cables, and the arrows point in the direction that the current flows to. (I.e from preamp to amp, or from source to preamp, etc...)
As to whether it makes a difference, who knows? I never bothered to try installing the cable in both directions and critically listen. I just followed their advice and installed it their way, assuming they knew what they were talking about. (Of course, we know the definition of "assume" though, so who knows!)
