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

Signal Cable Shotgun. Under $200 and probably better that anything under a grand.

MIT T-2 biwire..I auditioned 8TC,Harmonic tech.Pro-11's and the MIT's
Both the MIT and H.T. creamed the 8TC.
The MIT and H.T. were very close,almost identicle sounding,but the bass w/the MIT's was a tad deeper.
You can get a 10' biwire run of T-2's w/bananas for < $300..used of course.
The majority of cables have a rather "homogenous" sound in my estimation...and few vary greatly over generic copper "lamp cord" wire...harst but true...the one that really stands out IMHO...NORDOST...their SOLAR WIND and SUPER FLATLINE cables in your range really do bring a level of clarity and transparency few can rival...
