best speaker cable under $300?


I'm using DH labs Q-10 biwire and happy with it. now I need a longer pair. before buying another pair of Q-10, i wonder if there are better cables in this price range. I need a 10ft biwire pair with banana termination, and cost no more than $300 used or new.

I have a Musical Fidelity A300 intergrated amp with Monitor Audio Gold Ref 20 speakers

thanks in advance
