I have run "shotgunned" biwire cable configurations before when the biwire was not of sufficient gauge but I eventually replaced them with a larger gauge biwire cable. By all means try it and go with whichever way sounds best.
Double run of speaker cables?
Just thought I would ask a question about a double run of cables from amps to speakers. I have two sets of cable from bluejean cables. I'm utilizing spades and banana plugs both sets are bi-wired. Have any of you tried this, if so what are your thoughts and experiences.
