Wasatch interconnect direction

I have a pair of wasatch interconnects that I haven't used in a while. Does anyone know if the little arrow on the wooden block should point to the amp or to the source? Probably a dumb question, but I think I remember being told that it mattered
to the amp
Should point to the amp.
Away from the source.
In general the arrow should always point in the direction of signal flow, source>preamp>amp.
