I have been reading my @$$ off the past few weeks, and I want to thank ALL of you for the support. I am going to use Paradigm Studio 40's for the rear suppounds and eventually I will add a studio CC for the rear. I have already ordered some 4 comductor Acoustic Research in wall cable for the runs. Each run will be roughly 50ft. and I can biwire the speakers. Will I benefit any by using a single run of 12ga and not biwiring the speakers?
