The (original) MIT 330's are still great cables, just like the Straightwire Maestro and Maestro II. The boxes came later, and are an unnecessary electronic affectation IMO (unless of course your running lengths over 15 ft.)
I have a whole bunch of the stuff, but it all needs re-terminating. BTW, the arrowhead should point to the end of the cable where the shield is joined with the RCA ground 'ring', while the other end of the shield is left unconnected (floating).
The arrowhead end of all interconnects should attach to the preamp (including the pair between the preamp and amp.) The directional arrows have nothing to do with "current flow", since in AC (like a music signal) the current flows back and forth equally.
