how do I compute mine? I have multiple systems:
in HDMI cables alone, about 200-300 bucks
in speaker wire, i've bought 3.5 spools of 14 gauge wire and 2 spools of 12 gauge wire (100' per spool)
in coaxial wire, i've bought a 1000 foot spool of RG59 Belden cable.
and then in RCA tips, Banana Plugs, Spades, about 300-400
