Currently running a 5.1 set up via Onkyo 806 receiver with the 2 fronts in a 'bi amp' configuration ( separate runs from high/low terminations from speakers to receiver). I'm now looking at moving up to 7.1 which means the biamp configuration will have to go as the extra speaker inputs on the amp will be used. Should I just go back to using the gold plated bars supplied with the speakers , invest in some jumper cables( or cut to length the existing cables which i won't be using for jumper cables) or sell the Chord cables I've been using and buy bespoke ( reasonably priced) 2/4 biwire cables???
