I recently purchased canare 4S11 quad speaker wire to biwire my rear surrounds(b&w 805's) The length of the run is approximately 35 feet and 40 feet to the speakers. I was told at a high end audio store I shouldn't biwire this long of length, It would be much better to use the quad wire by combining two wires to each post. I believe they are each 14g each. Any one have any ideas as to the best way to connect them? Thanks
